Everyone looking for a new bed wants to get the best mattress they can. But, with so many brands and types, how do you know which mattress is best? The Best Mattress website’s simple guides, reviews, brand overviews, and shopping tips will help provide you with information to make a more informed decision. It really helps. One sample guide of the site is below:
Choosing the best latex mattress can seem a little difficult, as latex is one of the most difficult bed types to research. This is because latex is less common the innerspring or memory foam mattresses, and because the material has numerous quality aspects to consider. Before you buy a latex bed, it can be a good idea to learn the basics of this mattress type so you know what to compare and how to choose the best latex mattress for your preferences.
The basics of latex mattress shopping
As with any product, latex mattresses have specific features and facets that describe their qualities and properties. This guide will go over the basic terminology used for latex beds, including the basic types, methods of manufacturing, descriptions of firmness, mattress construction, and other important features.
Types of latex mattresses
The type of latex refers to what the material is made out of. There are three variations available:
Synthetic latex mattresses – manmade material, aka styrene-butadiene rubber. This product is made of petroleum-based ingredients, and may also be blended with polyurethane. Synthetic latex is cheaper to produce and more consistent in quality, but tends to be less resilient and less durable than natural latex. Natural latex mattresses – natural material derived from the hevea brasiliensis, or latex tree. It is tapped from living trees, producing a sustainable, eco-friendly product. Natural latex is highly durable, and produces resilient and uniquely supportive foam, but can be expensive to produce. Blended latex mattresses – A blend of both natural and synthetic latex, often with 30% natural and 70% synthetic. Blended latex is the most common material, and can be referred to as “natural”, but not all-natural or 100% natural. It yields some properties of both types, and tends to be priced in the middle range.
Latex manufacturing
Latex mattress manufacturing methods are also used to describe and categorize mattresses. The two primary methods used to make latex foam are Dunlop and Talalay. Both methods can utilize either natural, synthetic or blended latex.
The Dunlop method is the original process for producing latex foam. It involves mixing and frothing the latex, pouring the mixture into open molds, and heat-curing the foam. The material is then washed and dried.
The Talalay method was developed later, and involves a few more steps. After the mixture is frothed, it is poured into vacuum-sealed mold where the air is sucked out to create a uniform cell structure. The foam is then flash frozen to preserve the structure, then heat-cured. The finished foam is washed, usually multiple times, and then dried.
Dunlop foam is cheaper to produce, and thus costs less. However, when comparing Dunlop to Talalay, Dunlop latex is less consistent in feel, the irregular cell structure wears quicker, and it is more difficult to get softer, finer foams in the Dunlop method. Talalay latex is considered superior because it is more uniform and consistent, more resistant to compression, and can be made in a wider range of firmness.
Mattress construction
After considering the type of latex used in the bed, the next thing to examine is the construction of the mattress. This involves both the layers in the mattress and how the bed is put together.
A true latex mattress should consist of only latex foam, with no springs or other foams. Support comes from the latex core, which is a firmer base layer usually between 6 and 8 inches thick. Some mattresses are composed of the core only, th0ugh many also contain additional thinner layers of latex above the core that could range from 1 to 6 or more inches in thickness. The top layer of the mattress or the cover may have additional padding material such as wool or cotton, however this should be no more than 1 inch thick to preserve the benefits of the latex and prevent the impressions from developing.
These layers of latex can be assembled with or without adhesives. Bon- ded mattresses have the layers glued together (like most other mattress types). However, some brands do not glue the layers together, rather they layers a set atop each other within the mattress cover. This allows the owner to adjust or swap out layers, and also reduce household chemicals, as adhesives can include a number of potentially harmful volatile organic compounds (VOCs). Shoppers buying latex mattresses online may be especially interested in unglued mattresses, as the firmness or feel can be changed by swapping individual layers rather than shipping back an entire mattress. The ability to swap out compressed layers can also reduce long-term costs.
Firmness
Latex mattresses tend to have more specific descriptions of firmness than other types. This measure is described as the “ILD” or indentation load deflection. The number refers to the pounds required to compress a sample of the foam 25%. Thus, lower numbers refer to softer foams and higher numbers indicate firmer foams. Most mattress cores fall in the firm to super firm range, while upper layers can range from very soft to firm for different overall feels. It is important to take the ILDs of all layers into consideration when determining firmness. The ILD scale offered by Latex International, one of the major US manufacturers, suggests the following ILD ranges for classification:
Super Plush – 14, Plush – 19, Soft – 24, Medium – 28, Firm – 32, Extra Firm – 36, and Super Firm – 40-44.
Flame-retardants
All mattresses must now meet the federal guidelines for flammability; a measure designed to prevent house fires and improve safety preventer. Natural latex is less flammable than polyurethane foam and other materials, but manufacturers must still resistant materials or chemicals to meet user either the open flame tests. If they use a retailers says nothing, they may be uninformed. One of the more popular Methods of flame resistance barriers for natural latex mattresses is that either wool or foam surround the area built into the cover. Natural wool can provide in the flame resistance when used in specific treatments of tight weaves or with boron or other additives. Silica- treated rayon can also be used, as can other types of additives like arsenic or chemical retardants with potential side effects, so it is important to research how a mattress meets the guidelines if you are concerned about chemical exposure.
Mattress Covers
The final component to compare when shopping for a latex mattress is the cover material. The primary things to consider are the material’s breathability, durability and flexibility. Natural Fibers like cotton and wool are better at wicking moisture and do not inhibit airflow like synthetic materials. The fabric should also be able to stretch so the latex foam contour to your body can fully. Because latex beds can last upwards of 10 to 15 years, it is important that the cover material be durable as well. Cotton and wool are two ideal Candidates for latex mattress covers which are widely available. If you are concerned with chemicals or mattress you prefer to be as natural as possible, opt for certified organic cotton which is free of chemical pesticides and dyes.
Overview
Here is a quick summary of what to look for and compare when shopping for a latex mattress:
* Determine what the latex material is made of.
* If the natural latex is as described as natural, is 100% natural or a natural blend?
* Determine if the latex is made in the Dunlop or Talalay process for each layer.
* Determine whether the mattress is all-latex or whether it contains other materials.
* Identify the ILD of each layer and contrast this with your firmness preferences.
* Sea whether the mattress layers be customized or if they are bonded together.
* Ask how the mattress meets flammability requirements.
* Determine what the mattress cover is made of.
* See if the mattress has any thirdparty certifications, like organic materials or safety / quality certifications like Oeko-Tex.53
