What is a latex mattress?
Latex mattresses are made from natural or synthetically manufactured latex.
They comprise a latex foam layer that provides support for the body in a similar way to memory foam.
Many people have never heard of foam latex mattresses, but they were invented as far back as the 1920s (50 years earlier than memory foam). 🤯
Where does latex come from?
Natural latex is harvested from rubber trees and has been around since the 4th century BC.
As latex is harvested without damaging the tree, it’s considered a fantastic natural and eco-friendly alternative to man-made mattress materials.

In stark contrast, synthetic latex only dates back to the beginning of the 1900s.
The demand for synthetic materials like rubber is linked directly to the growth of the automobile, where it is used to make car tires, clutches, conveyer belts etc.
The Bayer lab successfully polymerised isoprene in 1909, and synthetic rubber was born.
Synthetic vs natural latex
Latex mattresses can be made from natural latex, synthetic (man-made) latex, or a combination of the two.
Natural latex mattresses
Natural latex is tapped from rubber trees (Hevea brasiliensis) and has been used in the bed industry for over a hundred years. 😮
There are two different processes used in the manufacturing of latex: Dunlop latex and Talalay latex.
Dunlop latex tends to be firmer, while Talalay latex is softer.
We go into more detail about this in our FAQs.

Not only is latex completely biodegradable, adding to its eco-friendliness, but its natural composition also ensures breathability for utmost comfort.
It's worth noting that, even with sustainable components, there is still an environmental footprint from the factory production of organic latex mattresses.
Synthetic latex mattresses
Synthetic latex is a man-made material produced to recreate the same feeling as natural latex at a much lower cost.
Synthetic latex mattresses potentially outlast all-natural latex mattresses in terms of durability, but they come with a few trade-offs.
For starters, synthetic latex doesn't conform to the body as well as natural latex, making it less ideal for pressure relief.
Originating from plastic in petroleum plants, its manufacturing process is also bad for the environment and contains chemicals and VOCs. ☠️
Blended & hybrid latex mattresses
Many people choose blended latex mattresses, which mix synthetic and natural latex, to achieve some of the benefits of natural latex at a more affordable price.
Alternatively, a latex hybrid mattress is a good alternative, combining a latex layer with other mattress materials such as memory foam and pocket springs.
The Rest Assured Knowlton 2000 Pocket Latex mattress is an excellent hybrid option:
What are the benefits of a latex mattress?
There are many benefits to buying a latex mattress. 💡
But we think they're particularly suitable for:
- Back and side sleepers
- Light to average weight sleepers
- Restless sleepers who don’t like feeling “stuck” in a mattress
- Environmentally-conscious people
- Warmer sleepers
- Couples
- Allergy sufferers
- Those looking for a similar alternative to memory foam
We'll examine the main advantages of latex mattresses and why they might be suitable below.
They provide exceptional pressure relief
Like memory foam, the best latex mattresses are flexible and easily contour to the body.

This encourages neutral spinal alignment and provides relief on pressure points.
However, while memory foam "hugs" around the body, the contouring effect of latex is much less intense.
This means latex is a great option for those looking for pressure relief without feeling hugged in by a mattress.
The contouring effects of latex make them a particularly good choice for side and back sleepers.
They have more bounce-back
Latex mattresses react quickly to pressure and spring back to their original shape almost instantly.
This gives it a slightly more elastic spring-like feel, making moving around on the mattress much easier.
This responsive and bouncy feel is ideal for those looking for the best mattress for sex.
They're also excellent at absorbing motion, so you shouldn't feel any disturbance from your partner during the night.
Natural latex mattresses are eco-friendly
Natural latex mattresses are derived from the sap of rubber trees, which can be produced for up to three decades.

The process of harvesting latex does not damage the trees or negatively impact the environment.
Moreover, all-natural latex mattresses are fully biodegradable, meaning there is a reduced burden on landfills. ♻️
They are more hygienic
Latex mattresses have the advantage of being hypoallergenic and resistant to dust mites and bed bugs.

As latex is very dense, dust mites cannot penetrate the material like they can with traditional mattresses.
Additionally, they have antimicrobial properties that deter bacteria accumulation, ensuring a cleaner sleep environment. 🧼
However, you should still use a mattress protector with a latex mattress.
Latex mattresses are naturally cool
Unlike many memory foam mattresses known to trap heat, latex mattresses are manufactured to have air pockets.

These pockets release any stored excess heat, making latex a cooler sleep alternative to memory foam.
They are highly durable
A standout feature of latex mattresses is their impressive durability.
They tend to outlast other mattress types, resisting common issues like dipping or indentations.
Latex mattresses typically last anywhere between 10 - 25 years.
So, while the initial investment in a latex mattress might be on the higher side, its durability ensures that it offers value over time.
The Hypnia Supreme Hybrid comes with a 15-year guarantee:
What are the drawbacks of latex mattresses?
While latex mattresses have many benefits, they're not for everyone.
Latex mattresses are less suitable for:
- Excessively hot sleepers
- Those who like to feel “hugged” by a mattress
- Elderly or disabled people who may have trouble moving the mattress (they're very heavy)
- People who are allergic to natural latex
- Budget-buyers
Some drawbacks might make a latex mattress a less suitable option for you.
We'll discuss them all below. 👇
Natural latex mattresses are expensive
100% latex mattresses, in particular, can be on the pricey side. 💰
If you're on a tight budget, then an organic latex mattress might not be the best choice.
Alternatively, consider a hybrid latex mattress, such as the Relyon Bridgwater Dunlopillo Latex mattress.
Some latex mattresses have an unpleasant smell
Some latex mattresses may emit an odour after they are unpacked.

The smell of natural latex mattresses should be very mild and smell of natural latex, which many people actually quite like.
Synthetic latex mattresses tend to have a stronger odour that has a more unnatural rubber or chemical aroma, which can be unpleasant.
Some latex mattresses arrive compressed and vacuum-sealed, which can also make them slightly odorous.
Unpacking your mattress and airing it out in a well-ventilated room for a few days should help the smell disappear.
Their composition is mysterious
Some latex brands market their mattresses as natural latex, but this often contains synthetic latex.
In some cases, the composition is 70% synthetic latex and only 30% natural latex.
This can make it confusing when shopping for a natural latex mattress, as it may be unclear if you're getting pure natural latex.

If you're unsure, we recommend opting for a trustworthy latex brand, such as Dunlopillo.
The Dunlopillo Royal Sovereign mattress is our favourite 100% natural latex mattress UK.

Difficult to move around
Moving around on a latex mattress is easy, but moving it can be more difficult than moving a regular mattress.

The high foam density in latex can make them heavy, which makes them difficult to move around.
Latex foam is also very flexible, making latex mattresses feel quite "floppy" despite the high density.
Synthetic latex mattresses are made from harmful materials
Mattresses made of synthetic materials are usually made of plastic fibres produced from petroleum.
Many chemicals are then added to improve the aesthetic appearance and technical properties of these mattresses.
These can include solvents, glues, chlorine for bleaching, anti-dust-mite sprays, phthalates to modify the flexibility of the foam and flame retardants to prevent your mattress from catching fire.
Most of these chemicals are a source of emissions of Volatile Organic Compounds (VOCs), which can have harmful effects.
We recommend choosing a pure natural latex mattress over synthetic options to avoid any health issues and reap the benefits of natural latex.

How to choose a latex mattress
Unfortunately, getting a great night's sleep isn't as simple as looking for the top latex mattress.
You should ask yourself some key questions before deciding if a latex mattress is right for you. 🔍
Consider the following criteria before choosing your latex mattress:
- Can I afford a latex mattress - if so, what’s my budget?
- Does the latex mattress come with a sleep trial and guarantee?
- Do I prefer a soft or firm mattress?
- Do I share the bed with a partner? (If so, what are their preferences?)
- What is my sleeping position?
Our guide on how to shop for mattresses online will give you even more bed-buying advice.
We also have some criteria to look out for when purchasing a natural latex mattress below.
Density & firmness
The density of a latex mattress can determine its firmness.
- A latex mattress with a density of 65 kg/m³ to 75 kg/m³ offers medium-firm support.
- A density of 75 kg/m³ to 80 kg/m³ will offer firm support.
- And finally, a density of 80 kg/m³ to 83 kg/m³ will offer very firm support.
Alternatively, most mattresses will have a firmness rating, so you know exactly what you're getting.

Read our firmness guide to determine what firmness you need for your sleeping position.
Number of comfort zones
Comfort zones provide additional support for areas such as the head, shoulders, and feet.

The more comfort zones a mattress has, the more the mattress will be able to keep your body in optimal alignment.
An entry-level mattress offers at least three comfort zones.
Thickness
Most models on the market are generally between 15 and 30 cm (5.9 and 11.8") thick.
In order to maximise comfort, we advise choosing the thickest mattress possible.
However, keep in mind that this will make the mattress heavier and more difficult to move.
Hybrid mattresses also tend to be thicker as they contain multiple layers of springs, foam, and latex.
How much do latex mattresses cost?
Latex mattress prices vary depending on the type of latex mattress and whether the latex is real or synthetic. 🤔
Pure natural latex mattresses can be more expensive than some alternatives, such as memory foam or innerspring mattresses.
Synthetic or hybrid latex mattresses can cost anywhere from £250.
Pure natural latex mattresses are likely going to cost £1000 or more!

But you don't have to buy the most luxurious latex mattress on the market.
Whilst we believe a good mattress should be essential for life quality, you should only buy within your budget.
If money is tight, consider a hybrid mattress with support foam or springs with a layer of latex on top.

Should you buy a latex mattress?
Latex mattresses can be excellent alternatives to traditional mattresses.
But natural latex mattresses are more expensive, so they may not be suitable for budget buyers.
However, they're also more durable, environmentally friendly, and very comfortable.
We'd suggest steering clear of synthetic latex mattresses if you're looking for a healthy and sustainable choice.
If you can afford it, a natural latex mattress is a no-brainer.
