Hybrid foams explained & boxed mattresses

Hybrid foams and boxed mattresses are the latest mattress trend. This new mattress material is causing confusion in the world of memory and latex foam mattresses. How do they differ and what exactly are hybrid foams? Here is our quick fix to give you the details on these hybrid Foams, often wrongly described as memory foam mattresses or equivalent. So let's take a closer look at hybrid foam mattresses.

Whilst memory foam and latex mattresses are the main foam bed contenders if you look around you also, will have seen other hybrid mattress materials adding yet more materials to read up on. They have different properties to both memory foam and latex so it is worthwhile finding out exactly how they differ. With a plethora of new hybrid mattresses entering the marketplace at any one time it can be really confusing.

What is a hybrid foam?

Both memory foam and latex have been around for over 20 years commercially and in the meantime, a number of other hybrid foams have been created. Many bed retailers will only refer to these with their brand names or will incorrectly classify them as a memory foam again confusing the area. We class any foam that is not technically memory foam (viscoelastic) or latex as a hybrid foam. Referring to any of these foams as memory foam or equivalent to natural latex is itself misleading. So if it doesn’t rely entirely on heat to soften and mould then its more than likely a hybrid mattress foam.

What is viscoelastic foam?

Memory foam is a viscoelastic foam that reacts to heat. If it doesn’t react to heat and have an open cell structure the scientists will argue it is not memory foam. That is why memory foam and Tempurpedic mattresses can get really warm. When it gets warm the open cell structure softens allowing it to mould to the shape of the pressure exerted on it, usually a sleeper. As you may have guessed there are again a number of different hybrid foams that offer similar properties and benefits to memory foam and latex. In addition, to being similar, a number of them have managed to remove the disadvantages of memory foam such as heat retention and rebound characteristics.

Hybrid foams are usually not viscoelastic.

What hybrid mattress foams are there?

There are literally hundreds of different branded foams out there. Whether its the Emma mattress, Caspers ‘Latex equivalent’, Eve’s next-gen foam, igel from Bensons for Beds etc you’re going to be bombarded with options. The problem is they all keep the detail of these foams secret. They don’t want you to know what properties they have. They argue its a trade secret but the issue is if you don’t know the exact depth of these hybrid foams then you have no idea how suitable their mattresses are going to be for you in the long term.

We have uncovered plenty of detail about two-hybrid foams that perform really well. Here are the details of the two of them with their data sheets so you know exactly how to compare hybrid foams.

What is Coolblue?

Coolblue consists of an advanced PU-based foam. It is one of the latest developments in foam.

Coolblue is cooler than memory foam and less heat retentive

It is less heat retentive when compared to memory foam making it a cooler foam however it will still be far warmer than a natural fibre mattress. It has a density of 70kg and is a firmer feel foam. Datasheets are really important when looking at a new hybrid mattress. This is the only way you can accurately compare them. Always make sure you ask any mattress retailer what the datasheet of the foams are.

This data must include:

  • Density in KG of the foam
  • Depth of each layer
  • ILD / Hardness Rating

Density and hardness are quoted according to in-house test methods based on BS EN ISO 845 and BS EN ISO 2439 respectively.

What is Laygel?

Laygel is a Synthetic Latex equivalent. It has a similar feel to latex but without the price tag given the fact its synthetic. It has an almost zero-viscoelastic threshold. This means it doesn’t rely on heat to mould like memory foam.Laygel Hybrid Mattress TopperLaygel moulds to the body but unlike memory foam, it does not rely as heavily on heat to fully mould, meaning it does not get as hot as memory foam. Due to this, it also returns to its original shape much quicker, meaning you’re not left with an indentation on your mattress as it returns to form. Memory foam is often criticised for people who roll over during the night as they often get stuck in one position as its slow to react.

Laygel removes this issue as it returns to its original form very quickly.

Laygel comes in a 60kg density meaning its medium in firmness on its own. When coupled with other foams and reflex foam this can be tailored to a softer/firmer mattress.

Brands of Hybrid Foam Mattress

The market place is currently flooded with hundreds of hybrid foam mattresses. You may be wondering where they have all come from. The issue with hybrid foams is that they are relatively cheap to produce and can be boxed for next day delivery. This means that a number of venture capitalists and investors have pumped money into new startups to get these fast products off the shelves in record time. This also means that the mattress expertise is often missing from these brands which is why they are only selling one size fits all one-sided mattresses. It’s a numbers game.

No turn mattresses
Hybrid mattresses can be spotted usually due to their fancy brightly coloured covers. But you really need to know whats exactly inside them!

The following are all brands of hybrid mattress you may be familiar with:

  • Casper Mattress
  • Eve Mattress
  • Simba Mattress
  • Leesa mattress
  • Emma Mattress
  • MADE Mattress
  • Otty Mattress
  • Nectar Mattress

They are all one sided, boxed and rolled hybrid mattresses using their own proprietary mattress foam. All claiming to be the perfect fit for all sleepers. Given that you may have very specific sleeping needs these models are likely to be a perfect match for everyone.

Drawbacks of Hybrid Foam Mattresses

Hybrid foam mattresses are fine up to a certain price point. They are cheap to produce, easy to roll and are a good entry-level option. However, if you’re spending £500 or more you can easily get a higher quality 2-sided mattress model for the same price. A 2-sided mattress will far outlast a one-sided hybrid mattress. It also means you can start to expect tailored spring tensions and more customisable fillings to match your sleep requirements more discerningly.

  • Hybrid mattresses are always one-sided
  • Hybrid mattresses don’t disclose the depth, density or types of foams they use
  • Hybrid mattresses are far warmer than a pocket spring fibre mattress
  • Rolling hybrid mattress models can end up damaging them
  • Hybrid foam mattresses have zero edge support
  • Hybrid mattress foams can’t be customised for your bodyweight
  • They offer a one size fits all comfort
  • Hybrid foams compress far faster than other fibres leading to sagging and dipping

How much should I spend on a hybrid mattress?

Given the fact that hybrid foams are relatively cheap when compared to a natural fibre upholstery the most, you should be looking to spend on one is £500. If you’re spending more than this then you can get far more from a customisable 2-sided pocket sprung mattress. If you’re spending more than this you’re paying for the brands marketing and snazzy packaging but not necessarily increasing the mattresses quality!

How much to spend on a double mattress?What can I expect for my money?
Under £500Will not get you much at best a 13.5 gauge open coil/cage sprung with a thin polyester layer or a solid foam mattress.
£500Entry level spunbond springs with some form of synthetic upholstery. Usually one sided mattresses.
£750The beginnings of a basic pocket springs unit with 800 – 1000 count. No substantial amount of filling other than foams and synthetic materials. Two sided models.
£1000Should get you away from most low ranges and into the mid-range pocket spring models.
£1250Should get you a decent pocket sprung mattress with some Natural Fibre content.
£1500Should get you many manufacturers mid-range models with Natural Fibres
£1500-£2000Should get you a Hand Made primarily Natural Fibre Quality Mattress
£2000+You should expect 100% Natural Fibres and Traditional Hand Made Construction Method.

Hybrid Foam Top 5 Tips

1- Hybrid foams are the next generation of foam beds. Many remove some of the drawbacks of memory foam. hybrid foams are often wrongly classed as memory foam but are really a foam in their own right. Only memory foam is viscoelastic, i.e. reacts to heat, whereas many hybrid foams are not viscoelastic.

2- Hybrid foams, such as Laygel and Coolblue remove some of the memory foam heat retention issues. They are therefore cooler to sleep on than traditional memory foam as they don’t retain heat as much.

3 – They have better rebound rates than memory foam, ie return to their original shape quicker. This is a benefit for those that don’t like the mould that memory foam creates around your body. It also removes the indentation affected were some sleepers struggle to turn over once the memory foam has moulded.

4 – Hybrid foams are often hyped to have special scientific and space-age qualities. Phrases such as ‘intelligent heat dispersal’ etc. Use your judgement as to whether this is true. Our hybrid foams are cooler and have quicker rebound rates which are the clear measurable difference. We disagree in selling a foam as intelligent or having its own ‘awareness’.

5 – You still need to consider the density, depth and quality of these hybrid foams just like any other material. If a retailer can’t give you these in confidence and explain the differences, then you may need to rethink that specific Hybrid foam/retailer as these factors are vital in choosing the correct mattress.



If you like the feel of memory foam but are put off by the heat retention and lack of response then a hybrid foam could be the answer. Not only are they far quicker to respond when you turn over but they don’t retain as much heat making it a cooler sleep surface when compared to memory foam.

However, they are always one-sided and do compress at an alarming rate. Which may lead you to need to replace your mattress far more quickly than if you chose a pocket spring model. If you need any more advice please get in touch with us on 0161 437 4419.
