Our winner in the Best Memory Foam Mattress category is the Nectar mattress, a 3 layer Centipur certified viscoelastic foam design, targeted at cradling your body, relieving pressure and dispelling heat through the layers. Designed and manufactured in the UK, this local lad comes with a hypoallergenic, quilted soft-to-touch cover. Each layer has been designed, as an addition to its purpose, to add airflow and temperature control.

Nectar Memory Foam Mattress Construction

The first layer is a Smart Memory Foam layer. Made from Nectar’s 5th generation, revolutionary memory foam, this layer is 30 times more breathable than other memory foams. This first layer not only hugs your body but also responds as you move, dispelling heat and moisture, regulating your body temperature. 

The second layer is a transition memory foam layer. This layer is made to cushion the blow so to speak. It absorbs energy, relieving pressure and keeping you at a consistent level of comfort throughout the night. This layer also acts as a transition, balancing out the layers and acting as a medium between them. The balancing doesn’t stop there, this layer also balances out any pressure disparities adding to the comfort maintenance.  

By having two upper memory foam layers, motion transference is drastically reduced, that is why we also rate the Nectar so high on our Best Mattress for Couples list.

The third and base layer is a castellated, 7 zoned base layer. This layer has optimum comfort and support, targeted at the hips and shoulders. The cutout zones in the base allow your hips and shoulders to sink deeper into the mattress, to keep your spine aligned, supported and comforted. The cut-outs in this layer also promote airflow, better adding to the cover and top layer’s temperature regulation properties.

Runnerup on our Best Memory Foam Mattress recommendations is from a company called Ergoflex. One of the first to bring the complete package online and to pave the way for the industry that is so heavily fragmented now. Their use of high-quality materials and cutting edge sleep technology has maintained its spot as a leading brand in the UK. Ergoflex uses high-density visco-elastic memory foam to provide superior body-moulding support, comfort and longevity. Let us find out just how good the 3 layered memory foam mattress is.

Ergoflex 5G Mattress Construction

The Ergoflex 5G Mattress is a 3 layered memory foam design, wrapped in a TENCEL® naturally breathable outer cover that is removable and machine washable at 30°. The cover is split into 2, the outer Tencel cover and the inner microfine layer that encases the mattress. The cover has 3D mesh panels on each end that add to the breathability and airflow in the mattress. The Tencel cover has additional natural benefits as well. Such as moisture-wicking which keeps things dry, it is naturally antibacterial and supremely soft and luxurious. 

The first layer is the visco-elastic memory foam layer. This layer is made from High-Density ACPT™ memory foam, which has billions of spherical shaped open cells that include orthopaedic pressure-reducing properties. (We rank the Ergoflex highly in our Best Mattress for Back Pain). This layer also helps to dissipate motion transfer, so your restless partner won’t get in between you and your rest. This layer is also designed to provide pressure-relieving support by shaping to your body. Interestingly, this type of foam is also used in hospitals throughout Europe, thanks to its health benefits

The second layer is the Cool-Sleep™ Airflow Layer. This layer is responsible for optimum sleep climate, keeping the air flowing and your mattress cool. This layer is also dome-shaped which not only helps with airflow but also suits body-conforming that cradles and hugs you, giving you that snug and cosy feeling. 

The third and final layer is the High-Resilience Base Foam layer. This impact-resistant foundation base layer provides strong support for the rest of the mattress while ensuring longevity in the long run. This layer is also designed to align your spine correctly, regardless of your sleeping position. This layer provides sufficient push-back so you won’t sink into the floor.

Ergoflex Extras

The Ergoflex 5G Mattress includes free next day delivery and returns, with a 30-night risk-free trial period with which you can try out the mattress in your home. Also included in your purchase is a 10-year warranty. Interesting about this is that Ergoflex is the only mattress-in-a-box brand that has been in business longer than their warranty.

– Machine washable cover with handles

The Emma Original Mattress is a 3 layer memory foam design, complete with a dual cover. The bottom half is breathable, while the top half is a temperature regulation cover. Proudly made in the UK, while conforming to all regulations, this multi-award-winning mattress has a supportive layer, pressure-relieving layer and a top breathable layer. How well do they work together? Let’s find out.

Emma Original Mattress Construction

The cover is hydrophobic, which means it dries quickly. Additionally, the cover fits snuggly on your mattress and thanks to the special fibres it regulates humidity and keeps moisture away. 

The first layer is Emma’s very own Airgocell® foam. This layer is a foam layer with more air pores than usual, making it highly breathable and which allows it to actively work to reduce heat through the night. This layer also has a quick response, this allows the foam to conform to your body’s movements whenever you move. This first polyfoam layer allows you to feel a cool, soft cloud-like feeling when you lay down.

The second layer is the pressure-relieving visco-elastic memory foam layer. This transition layer is placed between the support and cooling foam, which allows you to smoothly feel the benefits of all 3 layers. This layer has a slow-response, allowing the pressure to be distributed equally across the mattress and contour to your whole body. This layers purpose is to provide relieve especially for back pain. This layer also allows you to sleep in any position, as it will cradle to you with its slow response and provide pressure relief thereafter. 

The third and final layer is the supportive foam base cold layer. This layer is an HRX foam layer. This dense supportive base has castellated zones cut out into the base. These are placed at the hips and shoulders, which allows them to sink in while aligning your spine. The base layer is also exceptionally point-elastic, which means you won’t feel your restless partners movements.

Designed and manufactured in the UK, the Eve Original Mattress follows regulations and safety precautions. They even go as far as to source their materials from official National Bed Association members.

Eve Original Mattress Construction

The Eve Original Mattress has 3 layers and is wrapped in a 98% polyester and 2% elastane cover. The cover is highly breathable, hypoallergenic so it won’t cause the sniffles, removable and washable. The cover also includes 4 mattress handles for manoeuvrability. Eve suggests rotating your mattress top to bottom every few months to keep it in tip-top shape for longer.  

The first layer is the Evecomfort® Layer. This layer is designed to be 30 times more breathable than conventional memory foams, by using open-cell technology. This layer not only gives the mattress its bounce but also dissipates body heat, keeping things cool as you lay down and move about while sleeping. 

The second layer is the transition memory foam layer, which provides snug softness and keeps the pressure off. This layer actually provides pressure relief while contouring your body, without the traditional sinking feeling. It is placed in the centre to better distribute your body weight across the mattress. This allows you to feel the benefits from each layer smoothly.

The base includes 7 zones for hip and shoulder support, these castellated cuts into the layer allowing your hips and shoulders to drop into the mattress and keep your spine correctly aligned always.

The Casper Mattress is designed in the US and manufactured right here in the UK. All UK manufacturers must comply with local legislation to ensure products are safe for the public. This is no different with regard to Casper’s products. The Casper Mattress is an interesting 4 layer design, which is an extra layer as is normal in the industry. Complete with a removable, durable and washable cover, the Casper Mattress is possibly the most known brand from the bed-in-a-box industry.

Casper Mattress Construction

The 4 layer design enables a smoother transition between the layers, allowing each to perform as intended by Casper. The cover is made from 99% polyester and 1% elastane, which makes the cover breathable, durable and soft-to-touch. It includes 4 hidden mattress handles for manoeuvrability. The cover is also removable and washable at 40 degrees.

The first layer is the top open-cell layer, which is a polyurethane layer with more air pores than usually. The open-pore foam layer is soft while increasing airflow and breathability. This foam layer is quick in response, which means that it will react to your movement at the moment you move. This is the contact layer that provides the initial comfort. 

The second layer is the memory foam layer. Placed below the quick response, cooling top layer, this layer can do what it is meant for. Memory foam is known to retain heat, placing it below the breathable top layer allows for greater airflow and temperature regulation. This layer continues the body contouring and cradles your body. This high-density memory foam layer also supports pressure points and relieves pressure. 

Thirdly is the transition layer. This polyfoam layer acts as a bridge, between the upper softer layers and the supportive base layer. This layer also helps to evenly distribute weight across the mattress and relieves pressure from the more extruding areas of the body, such as the hips and shoulders.

The fourth and final layer is the high-density polyfoam base layer. This layer acts as the foundation for your mattress and includes channelled edging, which is cuts into the mattress. These cuts add zoning for the hips and shoulders to better align your spine by allowing these areas to sink into the zones, relieving pressure. These zones also allow for great airflow and breathability, keeping your mattress hygienic and cool.

Casper Extras

The Casper Mattress comes with free shipping, which usually takes 1 – 3 days to arrive. From there you’re free to try the mattress out in your home, making use of the risk-free 100-night trial. If it isn’t for you, you’re welcome to utilise Casper’s free return policy, within the trial period. Casper uses high-quality materials, which is evident in the 10-year warranty you receive with your mattress. This ensures that your mattress will last for a minimum of 10 years.

The Leesa Original Mattress is made in the UK and abides by all regulations, ensuring it contains no harmful chemicals. Leesa even donates 1 mattress for every 10 that they sell, promoting good community service.

Leesa Mattress Construction

The Leesa Mattress has a 3 layered design, with a single piece of fabric as the cover. Made from poly-lycra blend fabric, which is used in performance clothing, the cover is stretchy and highly breathable. The cover includes a 4 stripe design at the bottom of your mattress, this allows you to know which side is up, as rotating the mattress is advised for continued longevity. 

The first layer is the top cooling layer. This layer is made from Leesa’s patented cooling Avena® foam, which is a specially designed polyurethane foam. This layer has quick-response and moulds to your body and changes shape as you lay down or move. Additionally, this layer is less dense and has more air-pores than is usual in polyfoams. The design allows for more air circulation and makes the initial contact a softer experience when you lay down. 

The second layer is the intermediary memory foam layer. This layer is what cradles and hugs your body. Usually, this layer retains heat, but thanks to the top cooling Avena® foam layer, you can feel the benefits of the contouring without retaining heat. This layer also delivers pressure-relieving as it contours to your body. 

The third layer is the dense core support layer. This is a dense foam layer that strengthens, adds durability and structure that can support sleepers of all sizes.

Research and Resources for our Top Picks

In creating this “Best Memory Foam Mattress UK 2021” article, we:

  • Analysed many mattresses sold in the mattress industry (specifically the bed-in-a-box segment) including the mattress construction, closely looking at the memory foam used.
  • Went through the good, bad and ugly reviews left by customers.
  • Viewed all pros and cons to rank our list.
  • Spent hours researching, amending and updating this page to give the most useful information.

*This is our list that we came up with from being in the mattress review industry for quite some time now. We hope for this to serve you as a base point to conduct your own research to find which memory foam mattress is best for you and your unique preferences. If you do have a medical condition please consult with a medical professional before purchasing a mattress.

Types of Memory Foam

There are a few types of memory foams each with their own pros and cons. We have limited the types to what we see is most commonly used in the mattresses here in the UK. Below is a short explanation of the different types of memory foams that you should be aware of.

1. Traditional Memory Foam

This is the most used type of memory foam and is regarded as the least responsive. This is the type that generates the renowned hugging feeling that is so loved with memory foam.

  • Sleeps warm
  • Great for side sleepers
  • Pressure relief design

2. Open-cell Memory Foam

As memory foam is known to be heat retentive, engineers have designed a solution that has similar benefits to standard memory foam but with added/larger air pockets to allow for better air circulation.

  • Enhanced cooling
  • Quicker response
  • Similar feel to standard memory foam

3. Gel-infused Memory Foam

Another method used to create a cooler memory foam is the gel infusion method. This is created whereby gel (as liquid or beads) are infused in the manufacturing process. This reduces hot air pockets as its evenly spread across the surface.

  • Cooler feel
  • Dispensed heat

4. Proprietary Memory Foam

This is a very common form of memory foam in the UK. This is where mattress companies have formulated their very own foam with sometimes added ingredients such as graphite or copper. Here you should always research hoe the foam is made to get a better understanding if it’s worth considering for your next memory foam mattress.

Memory Foam Mattress Considerations

Here we just wanted to point out the most common questions and concerns with regards to memory foam mattresses. Do take these points into consideration when making your decision.

Hot Sleeper

Because of the characteristics of memory foam and its body conforming feel, many people feel it sleeps warmer as compared to polyfoam or hybrid mattresses. Pay special attention to the makeup of the memory foam, is it gel/ graphite infused, open-cell etc. this can reduce the warmth factor memory foam brings.

Keep in mind that the mattress cover plays a role. Covers made from thick and less breathable fabrics/materials may reduce the flow of air and affect the responsiveness of the memory foam layer.

Body Weight

Depending on your body weight you may need extra support. Memory foam thickness and overall mattress depth should be looked at as well as the maximum weight capacity the mattress can withstand. Our full-depth mattress reviews all include this information.

Sleeping Position

As memory foam has more of a sinking and soft feeling when compared to other mattress layers the positioning of it is crucial for various sleeping positions. Side sleepers may need more of the memory foam to be in the upper region to allow for more sinkage around the hip and shoulder area. Stomach sleepers are looking for more support to keep their spine correctly aligned. Back sleepers should look for a balanced feeling mattress.

Chronic Pain

Memory foam mattresses are known to be some of the best mattresses to provide that pressure relief, especially around the joints. High-quality foams are key here to maintain their pressure-relieving benefits. Be wary of cheap mattresses that may break down sooner than you would like. Luckily, all mattresses on this Best Memory Foam Mattress list include long-term guarantees and warranties to keep you secure in the long run.
