We’ve surveyed thousands of mattress-owning Which? members and members of the public about their mattresses to compile our definitive guide to the best and worst mattress brands and shops.
Our unique survey puts some of Britain's favourite brands to the test, including high-street names such as Argos, Dormeo, Ikea and Tempur, as well as online brands including Emma, Eve Sleep and Simba. We also rate popular mattress shops and online brands on the quality of their products, range, advice and delivery.
The results reveal the go-to brands for the most comfortable and best value mattresses – and the best places to buy them.

Which mattress brands do owners recommend?
We ask more than 3,597 Which? members and members of the public via an online panel about their mattresses to root out the most and least popular brands.
Our customer score is based on satisfaction with a mattress brand and the likelihood of recommending it to friends and family.
Our survey revealed a big difference in customer scores between the brands:
- The three brand at the top of our table received an impressive Which? customer score of 81%. Two of them are new to our survey
- Two brands on the bottom scored 73%
- Only two brands achieved a solid four stars out of five for value for money
- Eight brands received a disappointing two-star value for money rating

Which brand makes the most comfortable mattresses?
In our lab, we test body support, durability and pressure distribution, and independently assess how firm or soft a mattress feels, plus much more. But mattress comfort is harder to measure, because everyone's idea of comfort is subjective.
This is where our survey comes in. As well as asking Which? members and members of the general public to rate their mattress brand, we also ask them to report on how comfortable their mattress is.
Our unique survey results on this question are very revealing.
- Only five out of 20 mattress brands in our survey received a full five-star rating for comfort.
- The most common reason given for replacing a mattress was because it was uncomfortable (35%).
- One of the top reasons why members purchased a new mattress is because it felt comfortable in the shop, and was made by a trusted brand.

Best online mattress shops
Most high street mattress retailers have an online presence, but there's also a booming industry of online brands including Emma, Eve and Simba.
These brands sell their own-brand 'bed-in-a-box' mattresses direct to consumers.
None of the online mattress shops did badly at all in our survey but there were were some differences that could turn your mattress-buying experience from mundane to marvellous.

Should you shop for a mattress online or in-store?
Our survey revealed that mattress owners are divided on where they shopped for their mattresses: 48% bought their mattress in-store, while 52% shopped online.
Visiting a store lets you try out mattress materials and different levels of firmness, so it's easier to figure out what works best for you.
Try to lie on mattresses in your normal sleep position for around 10 minutes — it's worth feeling slightly silly to guarantee a good night's sleep.
Around half of mattress buyers (53%) visited a store to try out a mattress before buying, while a third (29%) said they bought their mattress at least partly because it felt comfortable in the shop.
However, if you're unable to get to the shops easily, buying online can in some cases offer more flexibility — especially if something is wrong with the mattress.
Brands such as Emma, Eve and Simba, recognise that their online-only offer limits your ability to try before you buy, so offer trial periods where you can try the mattress out at home before deciding if it's right for you.
Some sleep trials can be as lengthy as up to 200 nights or even a full 365 days, to give you a better chance to test your mattress. During this time you can usually return the mattress for a refund or exchange – just make sure you read the terms and conditions carefully before buying. They're not all created equal.

How we research mattress brands and shops
In October 2025, we asked 3,597 Which? Connect panel members and members of the general public who had bought a mattress in the past five years to tell us about their experiences via an online survey. To work out customer scores for mattress brands, we asked what brand of mattress people owned, whether they were satisfied with it and whether they'd recommend it to friends or family.
We also asked how they'd rate mattress shops for quality of advice, range of mattresses, value for money and ease of arranging delivery.
