Simba-Sleep-Logo-WM

We rate the Simba Hybrid as the best overall mattress that you can buy in 2021. With a medium-firm feel, hybrid construction, reasonable price point, and competitive accompanying policies, this mattress is a great choice for the vast majority of cases and should be one of your top contenders.

Simba’s Hybrid mattress has a 25cm profile made up of 5 layers (including the cover), each featuring impressive materials that exceed in the purposes they serve. For example, graphite-infused memory foams combined with titanium micro-coils contribute to excellent temperature control performance that will help keep you cool throughout the night. Albeit a hybrid by definition – meaning that it combines both coils & foam in its construction – the Simba mattress still feels more like a memory foam because of the micro sized springs. A benefit of this is that it can simultaneously provide targeted pressure relief whilst also enabling ease of movement so you don’t feel stuck.

Simba offer you a 200-night sleep trial so you can experience their UK-made mattresses for yourself. If it’s not to be, they will arrange a collection and will refund you in full. If you intend to keep the mattress, which we expect you will, then your purchase is assured by a 10-year warranty.

Emma-Original-Mattress-Review-Hero-WM

The UK’s most awarded mattress can add another trophy to its cabinet because we at What-Mattress rate the Emma Original as the best all-foam mattress of 2021. If you’re on the hunt for a medium-firm feeling mattress, that’s extra kind to the wallet without having to sacrifice all of the perks, then you can look no further.

Each of the 3 foam layers that make up this 25cm tall mattress possess unique properties to help you stay cool, avoid motion disturbance, change position, and feel well supported during your slumber. These features make the Emma Original a great choice if you sleep with a partner. In addition, it comes with a removable cover that you can unzip and throw in the washing machine for easy cleaning.

Being an all-foam mattress, the Emma Original has a lower price-point than other construction types that deploy more costly materials. If you think a cheaper price means cheaper quality, then you can rest assured that Emma back their models with a decade-long warranty. However, you can always find out first-hand by trialling it risk-free for 200 nights.

Best Luxury

Eve Premium Hybrid

Mattress Type: Hybrid

Firmness: Medium Firm

Trial Length: 100 nights

Warranty: 10 years

Sizes: Double, King, Super King

Ideal for:

Highlights:

We have awarded the Eve Premium Hybrid mattress as the best luxury mattress due to its superb build quality and use of up-market materials. If you are seeking a mattress with all the bells & whistles – and perhaps aren’t on the tightest of budgets – then Eve’s Premium Hybrid model is greatly recommended.

The luxuriously quilted sleeping surface of the Premium Hybrid mattress is interwoven with strands of silver, which Eve say is due to the precious metal’s antibacterial & antimicrobial qualities. Other ‘fancy’ materials include graphite, which has been infused into the foams in order to help extract heat from your body. Speaking of foams, there are four individual layers, each serving your body in various ways in order to provide supreme comfort. Underneath, fully-sized & pocketed spring coils will give you all the support you need, whilst also allowing your extracted body heat to dissipate.

Eve have packed a lot of high quality features into this mattress, yet have kept the price at a very reasonable level. Even still, you can break down the cost by financing at 0% interest and sleep easy knowing that your purchase is assured by a decade-long warranty. If you are thinking about upgrading to a luxury sleeping experience then why not give the Eve Premium Hybrid a go with their 100-night trial?

Brook + Wilde Logo

The Brook + Wilde Lux is the best mattress for couples because of its unique ability to be personalised on either half to the individual preferences of each sleeper. If you like a firm sleeping surface but your partner prefers a softer feel, then you can split the Lux down the middle and both sleep happily.

Since there’s two of you, performance in areas like motion isolation, temperature control, edge support, and ease of movement becomes especially important. The Lux mattress from Brook + Wilde achieves a high score in each of these key areas thanks to the carefully thought-out construction method and use of materials. For a detailed analysis of performance, you can take a read of our in-depth review.

Having bespoke firmness options on either half of the mattress comes as an additional perk and will have to be custom-made so bares extra cost. However, interest-free financing makes this quintessentially British mattress brand an easy choice for couples who don’t want to settle for a compromised slumber.

Otty's latest deal goes here

The best value mattress in 2021 is the Otty Original Hybrid. In terms of bang for buck, no other bed-in-a-box brand comes close to what Otty is offering, which is a 5-layer luxury feeling firm hybrid mattress at a shockingly low price point.

With a ratio of 64% spring & 36% foam, Otty’s Original Hybrid strikes a balance of support & comfort particularly suited to those of you who prefer a firmer sleeping surface. This could mean that you tend to sleep on your front, or perhaps are on the heavier side of the scales. This mattress is especially good at keeping you cool, minimising motion transfer, and supporting the edges so that you can make use of the full surface.

Otty usually price their Original Hybrid mattress starting at £599.99 for a size single, however they slash prices as much as 45% during sales periods so the same mattress is available at just £329.99. On top of this staggering value, interest-free financing let’s you spread the cost to just £30 a month. Additionally, shipping is completely free, you get a 100-night sleep trial, and a 10-year warranty.
