Best Mattresses

Top ten best mattresses in the UK in 2021

We've browsed mattresses online, we've tested mattresses at home, we've read reviews and best mattress lists from consumer associations, newspapers, magazines, and even other mattress review websites, and are proud to present our top 10 best mattresses in the UK in 2021.

Because we focus primarily on bed-in-a-box mattress reviews, we've also focused our top 10 list on bed-in-a-box mattresses and not mattresses available from traditional retailers.

We think bed-in-a-box mattress brands offer unbeatable value for money, and choosing these is often much more convenient than heading into an actual store.


Because there are so many benefits to ordering your mattress online, such as:

  • Greater variety
  • Great discounts and free gift options 🥳
  • Free delivery and returns
  • Risk-free trial periods with a money-back guarantee
  • Good warranty conditions

If you're unfamiliar with ordering a mattress online and need some guidance, you can check out our full article on online purchasing or our guide on how to choose a comfy mattress.

Then, if you're looking for more information on how to choose the best mattresses according to sleeping position, firmness, individual preference, etc., scroll down to the end of this article.

We expand upon each of those elements separately.

But, for now, let's get to our favourites.

Here are our top 10 best mattresses of 2021 👇

1. Emma Original

Emma mattress

The Emma Original mattress is the UK's bestselling mattress and has consistently appeared in best mattress lists for a number of years.

And for good reason: This is an exceptional mattress!

As a memory foam mattress with three layers of foam, the Emma Original has been designed for body-shape-contouring comfort, pressure relief, and optimal support.

While it is rated as a medium-firm mattress, we think the Emma Original qualifies more as a soft mattress.

We have given it a 4 out of 10 on our Sleep Hero firmness scale, where 1 is the softest and 10 the firmest.

Despite its softness, though, it's an excellent mattress that's exceptionally comfortable ☁️

It offers optimal spinal alignment in every sleeping position, but is particularly suitable for side sleepers.

The Emma Original is often recommended as an orthopaedic mattress to alleviate lower back pain due to its superior adaptability and relief of pressure points.

It also has great motion transfer capabilities, making it a great choice for couples.

Emma also offers one of the best pillows we've tried, which is a great addition to any mattress setup.

The brand-new Emma Original Hybrid, which is similar in comfort levels but comes at a much heftier price tag and has an entirely different composition, is also worth trying.


Emma Original
Material: Memory foam with a base layer of HRX cold foam
Firmness: Medium-soft; 4 out of 10 on our scale, with 1 being the softest and 10 the firmest
Sizes available: Single, small double, double, king, super king

Nectar memory foam mattress

The Nectar mattress is still relatively new on the British market but has already made an exceptional impact.

Composed of 3 layers of foam, this mattress has been designed to provide optimal spinal alignment, pressure relief, and comfort.

It has 7 contour zones to enhance its ergonomic design and keep your body in healthy alignment, no matter which position you lie in.

It is particularly comfortable for lighter and average-weight sleepers.

The Nectar is described as a mattress with medium firmness but we think it definitely falls towards the firmer end of the scale. We've rated it as 7 out of 10 on our Sleep Hero firmness scale, where 1 is the softest and 10 the firmest.

The Nectar mattress also has a removable cooling cover to provide for a comfortable sleep.

It comes with free delivery & returns, a revolutionary 365-day trial period, and a "forever warranty".

Firmness: Medium-firm; 7 out of 10 on our scale, with 1 being the softest and 10 the firmest

It features four layers, including a comfort layer of the patented Airgocell foam, supportive steel micro-coils, viscoelastic memory foam, and a base layer of supportive HRX foam.

The Emma Hybrid is a much firmer mattress than the Emma Original.

We've rated it at 7 out of 10 on the Sleep Hero firmness scale.

While still comfortable and cosy, the mattress is more suited to those who prefer a firmer sleeping surface and can better support slightly heavier weights.

With the added airflow provided by the springs, the mattress also allows for a much cooler sleep.

10. Dormeo Memory Plus

Dormeo Memory Plus

The Dormeo Memory Plus is a great budget mattress by Dormeo.

We've seen the IKEA Hövåg mentioned as a budget option in a few other best mattress lists, but really don't think the lower-end IKEA products can compare.

If you're looking for an alternative budget mattress, you can also consider the Eve Lighter Hybrid.

The Dormeo Memory Plus mattress combines eco-cell foam, which has a 3-dimensional cellular structure and provides efficient air circulation, with an extra-thick memory foam layer for body-hugging support 🤗

It also has four air vents for enhanced breathability, ensuring that the mattress never retains too much heat and remains at an optimal temperature.

This is a hypoallergenic mattress that features anti-bacterial, anti-dust mite, and anti-fungal protection AND is enhanced with anti-static carbon fibres, which makes this a particularly great choice for anyone suffering from allergies.


Dormeo Memory Plus
Material: Memory foam with eco-cell foam
Firmness: Medium-firm
Sizes available: Single, small double, double, king, super king
Mattress depth: 17 cm (6.6 inches)

Do sleeping position and personal requirements determine your choice of mattress?


Your preferred sleeping position definitely influences the type of mattress you should choose.

If you sleep on your side, for example, it's likely that you'll need a softer mattress, while stomach and back sleepers generally need a firmer mattress.

Other factors, like your height and body weight, also play a crucial role - especially when determining mattress firmness.

Similarly, personal requirements matter.

For example, if you're sharing your bed with a partner, you need to consider factors that wouldn't be as important if you were sleeping alone.

You’ll also need to consider who you’re buying the mattress for.

A single adult? A child? A senior?

All of these factors influence what the best mattress choice will be.

Best mattresses for side sleepers

We always recommend that side sleepers choose a softer mattress.

This is because side sleepers need a mattress that allows their hips and shoulders to sink in a little more deeply to achieve optimal spinal alignment.

Side sleepers should look for mattresses that:

  • Have high point elasticity (meaning that the mattress will give way where pressure/weight is applied but remain unaffected elsewhere).
  • Are a little softer.
  • Allow for ideal spinal alignment.
  • Come with integrated contour zones.

Suitable mattress materials include memory foam, cold foam, latex foam, and gel foam.

We wouldn't necessarily recommend pocket sprung mattresses as these tend to be on the firmer side and may cause back and neck pain, but hybrid mattresses are also a good option.


Best mattresses for back sleepers

Generally, back sleepers will benefit from slightly firmer mattresses.

This is because back sleepers require additional support, especially for the lighter parts of the body, like the head and feet.

If there isn't enough support at these points, your spine can't remain in an optimal alignment, which leads to lower back pain.

Back sleepers should look for mattresses that:

  • Have high-point elasticity.
  • Are a little firmer.
  • Allow for even pressure distribution.

We would recommend mattresses composed of springs, memory foam, gel foam, or cold foam.

We wouldn't recommend pure latex mattresses as these may be a little too soft and won't offer enough stability.


Best mattresses for stomach sleepers

Sleeping on your stomach isn't the healthiest position and can result in quite serve neck tension.

But, we know it can be quite comfortable for a short period of time.

Stomach sleepers should choose a firm mattress.

This is because firm mattresses provide sufficient support to the pelvis, which prevents the formation of a hollow back.

Stomach sleepers should look for mattresses that:

  • Are firm.
  • Allow for even pressure distribution.

We would recommend mattresses with a spring core, as well as hybrid mattresses made of cold foam, gel foam, or memory foam.


Best mattresses for couples

The best mattresses for couples have very low to no motion transfer - or good motion isolation.

This ensures that movements are effectively absorbed by the mattress and won't disturb your sleeping partner.

In addition, couples should look for mattresses with high point elasticity (to evenly distribute pressure) and a light suspension (to add a little bounce).

If you and your partner are of remarkably different body types, we'd recommend that you opt for customisable mattresses or even purchase two separate mattresses to form one larger double bed.


Best mattresses for babies and small children

If you're looking for the best mattresses for babies or small children under the age of six, it's important to pay special attention to the materials used.

Pollutants, toxins, chemicals, or otherwise harmful materials must be avoided at all costs. You can choose a certified mattress, or you could opt for a mattress with natural fillings, such as coir, wool, or latex.

A good cot mattress should not be too firm or too soft, but comfortable and capable of providing adequate stability.

This is necessary to ensure healthy growth and bone development 👶

You'll also want to look for a mattress with proper air circulation, which will help your little one sleep more comfortably.

Don't forget to invest in a quality slatted bed frame to assist with airflow and a waterproof mattress protector to safeguard the mattress.


Best orthopaedic mattresses

Most of the time, orthopaedic problems are not necessarily related to your mattress.

Stress, tension, a curvature of the spine, and muscular problems are much more likely to lead to orthopaedic concerns.

Sometimes, even an old or worn-out slatted frame may be the cause.

But, a bad mattress can certainly worsen your back pain.

If this is the case, a good orthopaedic mattress can help by supporting your spine and maintaining neutral spinal alignment.

For a mattress to have an orthopaedic effect, you must consider its firmness, point elasticity, and pressure relief capabilities.

Memory foam is a particularly good choice as it adapts so well to the body and provides cushioning.


Best mattresses for sex

It may surprise you to hear that some mattresses are better suited for sex than others.

Crucial factors to consider include stability, high point elasticity, bounce, and motion isolation.

Certain materials, such as latex foam, are particularly well suited.


Best mattresses for allergy sufferers

Allergies are quite common, and many people struggle with dust mite allergies 🤧

Unfortunately, dust mites often live in mattresses.

For people with allergies, it's worth considering mattresses that offer the following:

  • A removable cover that can be machine-washed at 40°C - 60°C.
  • Good breathability.
  • High density (to limit the space available for dust mites to breed).

We’d specifically recommend cold foam mattresses and mite-proof mattress encasings.

Allergy sufferers should also carefully consider their pillow and duvet choices. Synthetic materials, like microfibre, tend to work best as these are less likely to cause allergies.


Best mattresses for dogs

Your furry friend deserves a good night's sleep.

A good dog mattress will be:

  • Bite-resistant.
  • Easy to clean.
  • Moisture-repelling.
  • Easy to assemble.

We'll be updating this section soon to list some high-quality products. For now, watch this space 🐶
