ABOUT LATEX MATTRESSES

The process of making a latex core is like baking bread.  The outcome is a product that is all-natural; feels and smells natural.  And every piece is unique. 

 

On the other hand, spring mattresses are like a platform of PU foams, set on top of an assembly of metal coils.  Therefore, it is easy to describe a mattress with reference to firmness rating from 1-10.   

Buying a latex bed can be a little confusing at first.  So, we hope to cover some basic facts about Latex Mattresses to help you in your decision making.  Let's look at 4 areas:

  • The different types of latex mattress

  • How they are manufactured

  • Construction of a latex mattress

  • Firmness vs Density

1. SYNTHETIC LATEX

Also known as styrene-butadiene rubber (SBR), this is a man-made material. Synthetic Latex is made of petroleum-based components and is sometimes blended with polyurethane. Synthetic latex cores are cheaper and more stable in quality.

 

The downside is they are less resilient and less durable than natural latex.

Latex is harvested from the hevea brasiliensis, or rubber tree. It is tapped in liquid form from living rubber trees. It is a sustainable and eco-friendly product.

 

Natural latex is the most durable and is free of chemicals. It is naturally resilient to bacteria and fungi, and firm by nature. However, it is more expensive and harder to produce as it is more susceptible to the environment. 

3. BLENDED

A Blended Core is made from a mixture of both natural and synthetic latex, normally with 30% of natural latex or less and the rest is synthetic. This is the most common latex core in the market today. However, they are still marketed or even certified as  “100% natural” even though they are not all-natural. It yields some properties of both types but is not as durable and resilient as All Natural Latex Cores.

3 TYPES OF LATEX CORE

2 MANUFACTURING PROCESSES

1. DUNLOP

The Dunlop method was originally developed in the 1920’s and is the oldest method used in making Latex Cores. It involves the following steps:

  • Mixing: filling liquid latex into mould 

  • Vulcanisation: mould is put into oven to cure

  • Washing: remove core from the mould and washed

  • Drying: the final latex core is air dried

Dunlop cores cost less to produce as there as fewer steps and resource required. However, the material cost will be higher when a higher ratio of natural latex is used.   

2. TALALAY

The Talalay method is a newer method and involves more steps. The following are the steps:

  • Mixing: filling liquid latex into sealed mould 

  • Vacuum: removing air to disperse latex evenly in the mould 

  • Freezing: the latex is then flash frozen

  • Heated: the latex is the flash-heated

  • Washing: remove core from the mould and washed

  • Drying: the final latex core is air dried

Talalay latex is touted as superior by some brands and manufacturers, who say that the foam is more consistent and available in a wider range of firmness ratings.

DUNLOP V TALALAY

There are claims that Talalay latex is superior by some brands and manufacturers, who say that the core is more consistent and can produce a wider range of firmness ratings. This is due to the fact that it uses more synthetic latex to make the core.

 

Quick Facts for Dunlop 

  • More supportive mattress

  • Less bouncy

  • latex produced in a single piece and seamless

 

Quick Facts for Talalay

  • Softer and more conforming 

  • More bouncy

  • latex produced in sections and glued together, creating seams

MATTRESS CONSTRUCTION

A Latex Mattress truly should only consist of latex core; no springs attached or layered with PU foam. A 15 cm thick Latex core can provide support equivalent to a spring mattress 1.5 times thicker. 

For maximizing the benefit of sleeping on Latex:

  • the mattress should not contain thick covers: this will create a rigid sleeping surface and increases the chance of unevenness developing due to wear and tear of these non-latex materials.  

  • The outer cover should not be tightly sewn - it will restrict the natural elasticity of the latex core

  • A full Latex Mattress can be created with a single layer (single core) or multiple layers (multi-core).  

A single-layered mattress is made in the mould during the manufacturing process. However, when the thickness required exceeds the maximum thickness produced by the mould, the additional layers are then bonded to the base layer using latex glue. The outcome is a single-layer mattress of the desired thickness. The downside is that it can become too heavy for moving when required. 

A multi-layer mattress is a combination of a base layer and additional layers placed on top of it. Usually, these layers have their own inner lining that protects each layer and then the combined layers are placed inside a full overall cover. 
The advantages of a multi-layer system are the ability to mix and match different core densities to fine-tune its firmness and feel to the preference of the sleeper. Another benefit is the option for children to start with thinner cores and add layers as they grow heavier (Pay as you grow). 

FIRMNESS VS DENSITY

While spring mattresses use the terminologies like firm, orthopaedic firm, medium firm, plush firm or soft and some even uses numbers like 7/10, 8/10 and so forth, it is difficult for Latex Mattress to describe its support levels in those terms.

 

A Latex Mattress by nature provides an all-encompassing support to the sleeper. Therefore, it is safe to describe a latex mattress as always firm, support wise, and will always maintain a stable and conforming spinal support for the sleeper, regardless of his/her body shape. 

 

DENSITY of a Latex Mattress

A better way to choose the right latex core is perhaps based on how much conformity one is looking for. This normally relates to the density of the mattress core that makes up the single or multi-layer mattress. Through experience, most side sleeper would prefer a latex core with lower density as it is less compact.  This means less stress on his/her shoulder and hips, thus giving the sleeper a "softer" feel.  On the other hand, back sleepers usually prefer latex cores with higher density, which gives the sleeper a "firmer" more compact feel.

 

Therefore, for sleepers who have not slept on a full latex mattress, it would be easier to decide by sleep testing on one. 

In SUMMARY

Here is a quick summary of what to look for and compare when shopping for a latex mattress:

 

  • Check what type of latex is used to make the Mattress Core

  • If the latex is described as natural, determine if it is 100% All Natural or Blended?

  • Check if the latex is made in the Dunlop or Talalay process for each layer.

  • Check whether the mattress is fully latex or whether it contains other materials or fillers.
