Sleep Better with Talalay Latex Mattress

More and more people are talking about preferring to buy latex mattresses. More and more people are finding out the comfort of spring-less core mattresses.

Latex are softer and yet firm; and longer lasting. Many latex mattresses have lasted 20 years. With the right type, you can enjoy it even as long as 30 years.

Benefits of Latex Mattresses
1. hypo allergenic
2. mildew resistant
3. anti-microbial
4. dust mite resistant
5. optimal orthopedic support because latex conforms to body contours
6. cool to the body unlike urethane products because of its superior breathability
7. soft and firm – naturally springing back to its original form
8. no disturbing motion disturbance when your partner moves on his side of the bed
9. heat and moisture resistant
10. relieves the muscles and capillaries from pressure that suppresses proper blood flow and proper delivery of oxygen and vital nutrients throughout the body

The question is “which one” among the different choices should you use?

Do you choose the natural latex mattress over the synthetic latex mattress? Which one provides more comfort? Which one is more durable? What is the difference between Talalay latex mattress and Dunlop latex mattress? Are they designer brands for quality mattresses?

Is Talalay Latex Mattress the best choice for you?

You have to be sure before you part with your hard-earned dollars. After all, it’s not only the money that we’re talking about here. It’s your health!

That is something more important than any property that you can have or own. Your body deserves the best.

To start off, we should first understand what latex is. Latex is foam that is basically divided into 3 types based on the material used:
1. Natural
2. Blended
3. Synthetic

Natural Latex

The natural latex comes from the sap of rubber tree. The milky white sap is collected and combined with water then whipped with air in. When molded, the air bubbles are trapped inside and thus, rubber foam is produced.

Blended Latex

Blended latex is simply a combination of the natural rubber sap and some chemicals to achieve the same cellular structure and product at a cost that is less than 100% natural latex. This is what’s predominantly sold in the market today to give the consumers the comfort and rest that they want while keeping the prices more affordable.

Because blended latex indeed has natural rubber as part of the raw material used, it is sometimes categorized under natural latex.

Synthetic Latex

Synthetic Latex or man-made latex is styrene butadiene rubber (SBR). This type of latex is made from chemicals and petroleum and exhibits the same cell structure as natural rubber latex.

Whether natural or synthetic, latex are further divided into 2 sub-types characterized by the process used for each:

1. Dunlop latex mattresses
2. Talalay latex mattresses

The Dunlop Process

This is also usually called the standard process. Dunlop is a manufacturing process which was originally used to blend natural rubber sap and synthetic chemicals together. Air bubbles are whipped into the blended liquid before the liquid is poured into the mold then gelling agent is added.

Because the liquid sets slowly, gravity affects it and settling of material occurs. This makes the finished product acquire an uneven consistency.

The same Dunlop process has eventually been used in making not only blended latex but 100% natural Dunlop latex as well; although this type of all natural latex has a limited quantity which is a very small portion of all the Dunlop latex that are sold in the market.

The Talalay Process

Talalay Latex follows the same basic standard process but added a few more steps. After the blended liquid is poured inside the mold, air is vacuumed out before adding more of the liquid material into the mold. After that, the material is blast frozen to prevent the material from settling, thus avoiding the consequence of having uneven consistency of the finished product.

Talalay latex is softer than Dunlop latex from top to bottom and has shown to be more resilient; bouncing back to its original form even after years of consistent compression.

What’s Available for you out in the Market?

Both Dunlop and Talalay latex mattresses are mostly blended latex. This is so in order to get the best characteristics out from both the natural rubber and synthetic chemicals. This also makes your mattresses more affordable on the pocket.

A small portion of what’s available in the market today sells all natural Dunlop latex.

And an even smaller but fast growing quantity are the all natural Talalay latex that are sold in the shops. This is so because around the world, only 2 companies manufacture all natural Talalay latex — Dunlopillo in England and Latex International in USA.

Choosing The Right Mattress

In buying the right mattress, you are not limited to choosing Talalay or Dunlop; or synthetic, all natural or blended. There’s more than meets the eye.

A mattress can be made using pure talalay, pure Dunlop, or mixed of both. Mattresses can have fillers too. And what about memory foam mattresses? Are they made of latex too? Just to give you a heads up, memory foam mattresses are NOT made of latex and lack the breathability of latex.

Is it possible to buy all natural Talalay latex mattresses? The answer is YES. Can you afford it? If rest and health are important to you, the answer should be yes.

If budget is a constraint, can you buy blended Talalay latex mattress? Or if you want the softness and consistency of a Talalay latex mattress but cannot afford to buy the size of a whole mattress, here is a more budget-conscious tip:

Buy a blended Dunlop latex mattress for its firmer quality and a Talalay latex mattress topper of 2 or 3 inches. This way, you have a stronger base and still enjoy the softness and less resistant Talalay latex mattress.

Ask the mattress seller to sell you one that has no filler and perimeter support called racetracking. This perimeter support usually uses cheap polyurethane material which gives firmer edges, taking up 20% of the sleeping surface, which means that you will have less sleeping area unless you will be comfortable sleeping in the more resistant edge.

Now that you know better, you will be able to ask the right questions; buy the best mattress that suits your back pain and get the value for your money and body.

Solution: WordPress WPImageEditorImagick instruction injection vulnerability

Vulnerability Name: wordpress WP_Image_Editor_Imagick instruction injection vulnerability
In the /wp-includes/media.php _wp_image_editor_choose function internally found (probably at 2898 lines):

  1. $implementations = apply_filters( ‘wp_image_editors’, array( ‘WP_Image_Editor_Imagick’ ,  ‘WP_Image_Editor_GD’ ) );

change to:

wordpress removes the wp-json link and the wp-embed.min.js file

Recently updated the latest version of the wordpress 4.4, update what function I do not know, I know I do not have access to, but found that there are several functions inside the link function, I do not have access. So we removed him, mainly more REST API (through the REST API can easily access the site’s data), wp-json link, embeds function (embeds function can allow more convenient reference to third-party resources) wp-embed.min.js file.
We do not have to load it to do what, but also affect the site to read the speed, then we talk about how to prohibit out.
First talk about the disabled REST API, remove the wp-json link method, add the following code to the theme functions.php file to disable the REST API and remove the head inside the output of the link information:

  1. add_filter(‘rest_enabled’, ‘_return_false’);
  2. add_filter(‘rest_jsonp_enabled’, ‘_return_false’);
  3. remove_action( ‘wp_head’, ‘rest_output_link_wp_head’, 10 );
  4. remove_action( ‘wp_head’, ‘wp_oembed_add_discovery_links’, 10 );

Disable embeds is actually more complex (code more), the official and even developed a plug-in for this, we can use the plug-in to disable: Disable Embeds, if you do not want to use plug-ins, then plug the code inside the copy to the theme functions.php File can be.

  1. function disable_emojis() {
  2. remove_action( ‘wp_head’, ‘print_emoji_detection_script’, 7 );
  3. remove_action( ‘admin_print_scripts’, ‘print_emoji_detection_script’ );
  4. remove_action( ‘wp_print_styles’, ‘print_emoji_styles’ );
  5. remove_action( ‘admin_print_styles’, ‘print_emoji_styles’ );
  6. remove_filter( ‘the_content_feed’, ‘wp_staticize_emoji’ );
  7. remove_filter( ‘comment_text_rss’, ‘wp_staticize_emoji’ );
  8. remove_filter( ‘wp_mail’, ‘wp_staticize_emoji_for_email’ );
  9. add_filter( ‘tiny_mce_plugins’, ‘disable_emojis_tinymce’ );
  10. }
  11. add_action( ‘init’, ‘disable_emojis’ );
  12. /** 
  13. * Filter function used to remove the tinymce emoji plugin. 
  14. */
  15. function disable_emojis_tinymce( $plugins ) {
  16. if ( is_array$plugins ) ) {
  17. return array_diff$pluginsarray( ‘wpemoji’ ) );
  18. else {
  19. return array();
  20. }
  21. }
  22. function disable_embeds_init() {
  23. global $wp;
  24. $wp->public_query_vars = array_diff$wp->public_query_vars, array( ’embed’, ) );
  25. remove_action( ‘rest_api_init’, ‘wp_oembed_register_route’ );
  26. add_filter( ’embed_oembed_discover’, ‘__return_false’ );
  27. remove_filter( ‘oembed_dataparse’, ‘wp_filter_oembed_result’, 10 );
  28. remove_action( ‘wp_head’, ‘wp_oembed_add_discovery_links’ );
  29. remove_action( ‘wp_head’, ‘wp_oembed_add_host_js’ );
  30. add_filter( ‘tiny_mce_plugins’, ‘disable_embeds_tiny_mce_plugin’ );
  31. add_filter( ‘rewrite_rules_array’, ‘disable_embeds_rewrites’ ); }
  32. add_action( ‘init’, ‘disable_embeds_init’, 9999 );
  33. function disable_embeds_tiny_mce_plugin( $plugins ) { return array_diff$pluginsarray( ‘wpembed’ ) ); }
  34. function disable_embeds_rewrites( $rules ) { foreach ( $rules as $rule => $rewrite ) { if ( false !== strpos$rewrite, ’embed=true’ ) ) { unset( $rules$rule ] ); } }
  35. return $rules; }
  36. function disable_embeds_remove_rewrite_rules() { add_filter( ‘rewrite_rules_array’, ‘disable_embeds_rewrites’ ); flush_rewrite_rules(); }
  37. register_activation_hook( __FILE__, ‘disable_embeds_remove_rewrite_rules’ );
  38. function disable_embeds_flush_rewrite_rules() { remove_filter( ‘rewrite_rules_array’, ‘disable_embeds_rewrites’ ); flush_rewrite_rules(); }
  39. register_deactivation_hook( __FILE__, ‘disable_embeds_flush_rewrite_rules’ );

Every time you update the wordpress version will be more things, such as the previous emoji, and are input on the page content, more or less will affect the speed, our blog is basically updated under the article, engage in too much responsibility for the excessive, Not to get rid of REST API and embeds, for the user experience, so that the website faster display of our code on the OK.

WordPress front end user center often used data and access methods

In the development of ordinary WordPress theme, we have ready-made theme can refer to, but the development of WordPress front-end user center, we are not easy to find a reference, probably because WordPress front-end user center needs no common theme The This article will introduce some of the development of WordPress front-end user center users often to some data acquisition method.

Global variables:

  1. $authordata
  2. $post
  3. $wp_query

Get the author archive page link

  1. echo get_author_posts_url( $authordata->ID );

Get the author’s nickname

  1. echo esc_attr( $authordata ->display_name )

Get the number of comments, use in loop:

  1. echo $post->comment_count

Get comment link, loop use:

  1. comments_link()

Get the current login user information

  1. $current_user = wp_get_current_user();

Gets the user information that needs to be operated

  1. global $wp_query;
  2. $author = $wp_query->get_queried_object();

Above is the development of front-end user center wordpress time often used in some of the data acquisition method, of course, this is only part of which I will be in the development of front-end user center when the accumulation gradually added for your reference.

Prohibit wordpress4.4 + version automatically generates a 768 pixel thumbnail

4.4 version later, wordpress added a responsive picture function, the purpose is to allow the picture to adapt to the phone, tablet and other different screens, you upload the picture will automatically generate a 768 pixel thumbnail, but I do not want this feature, the Thumbnail size is fully adjusted to 0, prohibit wordpress automatically generate thumbnails, upload pictures or will generate a 768 pixel thumbnails.

This problem I find a long time did not find a solution to study the day, finally resolved.
In the document wp-admin \ includes \ schema.php Lane in the following code, you can see is 4.4 new features.

  1. // 4.4.0
  2.     ‘medium_large_size_w’ => 768,
  3.     ‘medium_large_size_h’ => 0,

This is the default option to install wordpress, but there is no place to change in the background, there is no change code, because it has been deposited into the database, so go into the database.
Enter the command to change the value of medium_large_size_w to 0 on the line
SQL commands are as follows:

  1. SELECT * FROM `wp_options` where option_name=’medium_large_size_w’

Prohibit wordpress generation 768 pixel thumbnails can effectively save the site space, especially those pictures of many sites (such as the theme of the cat wordpres theme download station) need to prohibit this thumbnail.

WordPress links are automatically added Noopener Noreferrer

I do not know if there is no need to put the chain in the article, taking into account the problem of SEO will generally give the site an article outside the chain automatically nofollow function, nofollow is an HTML tag attribute value. The meaning of this tag is to tell the search engine “Do not follow the links on this page or do not track this particular link.
Beard recently in the editorial website when the article found outside the chain can not automatically add nofollow attribute, after some research is the new version of the wordpress problem.
WordPress automatically adds the new Noopener Noreferrer attribute (resulting in the nofollow property failure) for all links that require a new window in the most recent version update.
Noopener Noreferrer property is not a new release standard, but v4.7.4 version of the WordPress editor will add the default by default.
This property is mainly used to prevent new windows from opening links when there may be phishing attacks, so as a security content WordPress gives added.
But after the addition of the new tab page will not be able to follow the conventional method to track the source page, which in the attribute field has been able to see: No Refer.
After the upgrade to WordPress v4.7.4 version of the original release of the contents of the new window link does not automatically add Noopener Noreferrer.
But if it is a new article or you modify the contents of the previous release, then the new window link will add Noopener Noreferrer.

Please add this code to the bottom of your wordpress theme at function.php and save and upload it

  1. //WordPress links auto add Noopener Noreferrer
  2. add_filter(‘tiny_mce_before_init’,’tinymce_allow_unsafe_link_target’);
  3. function tinymce_allow_unsafe_link_target( $mceInit ) {
  4. $mceInit[‘allow_unsafe_link_target’]=true;
  5. return $mceInit;
  6. }

Precautions:
Add the newly released content after the link if set to a new window open then the Noopener Noreferrer property will no longer be added automatically.
If the previously published article has been attached to the property even after the addition will not automatically remove, you need to manually edit and then delete the new attribute.
That is, manually edit the article and switch the editor to text mode and then rel = “noopener noreferrer” deleted and then save the update on the line.

WordPress website on the line before you have to complete these five things

In the site of the user exchange group which chat, found that many people always ask a question: the site before the line, what needs to be done? I think this question makes sense. According to past experience to sum up, share the theme of the cat’s friends.
Each site may have its own differences, but there are a lot in common. For the WordPress site, before you go online, you should complete the following five things:

1. prohibit search engine index.
This is because when you just started building the site, it is not suitable for search engine content included. At this time, the site content has not yet been built, some text is only some of the presentation. If the search engine contains the content, it is terrible, because the user to see such a content will have a bad impression on your site. You can in the WordPress management background [settings] -> [read] page settings: shielding search engine index site content. Of course, after everything is ready for the site, do not forget to modify the settings here, allowing the search engine to index the site content.

2. Check the website link.
Make sure that all links within the site are working properly. If the site has a failed link, it will affect the site’s SEO ranking. We have a few days ago to recommend you Broken Link Checker free plug-in, can help you complete this work. (To the bottom of this article)

3. Modify the thumbnail size.
When you change the WordPress theme to the site, it’s important to modify the thumbnail size because the thumbnails of many topics are not the same size.

 

4. Check the contents of the website twice.
Including the sidebar of the site, footer area, and navigation bar. We often leave some text errors, especially when you stare at the same site content text for a week, so please check it carefully.

5. View the website with your phone.
If conditions permit, try to check the appearance of your website with a variety of different mobile phones and Internet devices. Otherwise, if you only have a large screen PC, you can also try to continuously reduce the width of the browser to see the appearance of the site in different sizes.
If you have any special experience, welcome to communicate with us through the message.

How to modify the name of the WordPress default role

WordPress provides five default roles, different roles have different permissions, decide what they can and can not do; for example: whether the right to write or review other people’s articles; whether the right to replace the site theme. However, WordPress does not allow you to directly modify the default role name. However, it is not difficult to do it, the theme cat today will tell you how to modify these default roles.
WordPress default 5 roles are: Admin, Editor, Author, Contributor, Contributor, Subscriber.

Why do I need to customize the role name?
For users who use WordPress to build a personal blog, there is no need to modify these role names, because he generally does not use these. But for the corporate website is necessary.
WordPress after the acquisition of WooCommerce, the use of WordPress to build foreign trade sites and online mall users will be further increased. If you use WordPress to help customers to do an e-commerce site, site visitors (that is, potential customers) will be very strange, why their identity is Subscriber (subscribers)? Therefore, this time must deal with this problem.
To modify the default role of WordPress, you only need to write down the code to copy the functions.php file or the site-specific plugin for the theme you are using:

  1. function wps_change_role_name() {
  2.   global $wp_roles;
  3.   if ( ! isset( $wp_roles ) )
  4.    $wp_roles = new WP_Roles();
  5.   $wp_roles->roles[‘contributor’][‘name’] = ‘Owner’;
  6.   $wp_roles->role_names[‘contributor’] = ‘Owner’;
  7. }
  8. add_action(‘init’, ‘wps_change_role_name’);

The name of the Contributor role is changed to Owner (owner, owner). Here you can also use the Chinese, but must remember to save the file as utf8 no bom format, otherwise the Chinese may be displayed as garbled.
This code comes from Kevin Chard’s website. And then look back at the role of the site, turned into this:

However, it should be noted that this code is only the name of the Contributor role modified, and will not modify the corresponding permissions, nor add a new role, and even the role of slug (abbreviation, alias) will not modify.

WordPress Code Tuning: Administrator and Manage Background (Console, Dashboard)
1. Modify the Logo (logo) in the WordPress website login interface
First introduce a technique related to website branding: If you plan to modify your website (or your client’s website) login interface in the WordPress Logo, the following code is just right for you. Use it very simply, just copy the following code into the funcitons.php file on your site’s theme, or in a plugin dedicated to your site:

  1. function my_custom_login_logo() {
  2.     echo ‘&lt;style type=&quot;text/css&quot;&gt;
  3.         h1 a { background-image:url(‘.get_bloginfo(‘template_directory’).’/images/custom-login-logo.png) !important; }
  4.     &lt;/style&gt;’;
  5. }
  6. add_action(‘login_head’, ‘my_custom_login_logo’);

And then do their own Logo, named custom-login-logo.png, upload to the use of the theme directory within the images folder. This code we introduced, but also introduced how to modify the default Logo corresponding to the URL.

2. Modify the Logo of the WordPress management background (dashboard)
Want a WordPress site to stay closer to your business, feel more cordial? Replace WordPress management background (console, dashboard) in the upper left corner of the default WordPress Logo it. Many plugins can do this, but the following code can also directly achieve this function. Similarly, copy the following code into the theme’s funcitons.php file, or in the theme-specific plugin:

  1. function custom_admin_logo() {
  2.   echo ‘&lt;style type=&quot;text/css&quot;&gt;
  3.           #header-logo { background-image: url(‘.get_bloginfo(‘template_directory’).’/images/admin_logo.png) !important; }
  4.         &lt;/style&gt;’;
  5. }
  6. add_action(‘admin_head’, ‘custom_admin_logo’);

Then, you want to use the WP management background in the logo named admin_logo.png, uploaded to the use of the theme directory within the images folder.

3. Close the WordPress login box prompt function
To ensure the security of the WordPress site, it is important that we have written many articles on how to enhance the security of the site. We introduced this technique, but it is a very simple step, but also very useful. The default emptied, when you want to enter the account information log WordPress background, if you enter the information is wrong, WordPress will tell you the error message: the user name does not exist, or password error. This trick is to turn off such tips to enhance the security of the WordPress site.
To disable WordPress login error message, you need to copy the following code into the theme of the funcitons.php file, or within the site-specific plugin:

  1. function no_wordpress_errors(){
  2.   return ‘GET OFF MY LAWN !! RIGHT NOW !!’;
  3. }
  4. add_filter( ‘login_errors’, ‘no_wordpress_errors’ );

In this way, WordPress no longer outputs valid hints that can reduce the likelihood that the site will be compromised.

4. Keep the WordPress login status longer
If you are using WiFi or other wireless network, or use the public computer when the Internet, log on any one site, we must remember to withdraw in time. However, if you at home or company, use their own computer, after a while will be kicked out by WordPress, need to re-login, then it is also very annoying. At this time, you can try this technique to extend the retention time of WordPress login status. Likewise, copy the code into the funcitons.php file or in a site-specific plugin:

  1. add_filter( ‘auth_cookie_expiration’, ‘stay_logged_in_for_1_year’ );
  2. function stay_logged_in_for_1_year( $expire ) {
  3.   return 31556926; // 1 year in seconds
  4. }

By default, if you select the “Remember Me” option when you log in to WordPress, WordPress will remain logged in for 2 weeks. In the above code, we set it to 1 year.

5. Replace “Hello” with “Login as …” in the WordPress toolbar
If you think WordPress at the top of the menu toolbar, the default “Hello” is not suitable for formal occasions, or you want to change a welcome message, please copy the following code to functions.php file, or on the website dedicated plug-in:

  1. function replace_howdy( $wp_admin_bar ) {
  2.     $my_account=$wp_admin_bar-&gt;get_node(‘my-account’);
  3.     $newtitle = str_replace( ‘Howdy,’, ‘Logged in as‘, $my_account-&gt;title );
  4.     $wp_admin_bar-&gt;add_node( array(
  5.         ‘id’ =&gt; ‘my-account’,
  6.         ‘title’ =&gt; $newtitle,
  7.     ) );
  8. }
  9. add_filter( ‘admin_bar_menu’, ‘replace_howdy’,25 );

In the third line of the above code, the $ newtitle parameter can set the desired greeting. If you want to use Chinese here, please remember to save the file as UTF8 no BOM format.

6. Modify WordPress to manage the background footer text
Brand promotion is to convey information and consistent. So if you create a website for your customers, what you want to do for yourself makes your customers happy and very important to them. Therefore, in addition to changing the login page and management background of the upper left corner of the Logo, you can also manage the background part of the background to add the customer’s slogan (corporate values, vision, etc.) or other interesting text.
Cool! Place the following code in the funcitons.php file, or within the site-specific plugin:

  1. function remove_footer_admin () {
  2.   echo &quot;Your own text&quot;;
  3. }
  4. add_filter(‘admin_footer_text’, ‘remove_footer_admin’);

Now, you can add some here to give people a deep impression on the text, or quote some inspirational, connotation of the text, on the echo that line in the double quotation marks on it

 

7. Add short code to the gadget (pendant)
Short code (shorcode, also translated as “short code”, “short code”, etc.) super useful, because they only need a pair of square brackets, you can replace the original very long code snippet. By default, WordPress Widget (pendant, gadget) does not support short code, can only speak short code as ordinary word processing. However, you can simply use the following code in the functions.php file for the theme you are using, or within the site-specific plugin, you can use the short code in the gadget:

  1. define(‘widget_text’, ‘do_shortcode’);

In this way, you can use short code in Widgets (gadgets).
