Which mattress brand to buy in 2025

We've surveyed thousands of Which? members about their mattresses to compile our definitive guide to the best and worst mattress brands and shops.

Our unique surveys put some of Britain's favourite brands to the test, including high-street names such as Dormeo, Ikea, Hypnos and Tempur, and 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 3,530 Which? members 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 brand at the top of our table received an impressive Which? customer satisfaction score of 83%
• The brand on the bottom scored 68% for Which? customer satisfaction
• Only one brand achieved the full five stars for value for money

Mattress brand scores

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 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 8 out of 18 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 (26%).
• One of the top reasons why members purchased a new mattress is because it felt comfortable in the shop. The number one reason? It had a Which? recommendation.

These brands sell their own-brand 'bed-in-a-box' mattresses direct to consumers.

None of these online mattress shops in our survey did badly in our survey but there were were some differences that could turn your mattress-buying experience from a chore into a pleasure.

Should you shop for a mattress online or in-store?

Our survey revealed that Which? members are divided on where they shopped for their mattresses: 47% bought their mattress in-store, while 53% shopped online.  

If you can, do both. 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.

Get started

Around half of mattress buyers visited a store to try out a mattress before buying, while a third said they bought their mattress at least partly because it felt comfortable in the shop.

However, buying online can, in some cases, offer more flexibility — especially if something is wrong with the mattress.

That's because brands such as Emma, Eve and Simba, recognise that their online-only offer limits your ability to try before you buy. 

That's why most offer trial periods, some as lengthy as up to 200 nights or even a full 356 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.

How we research mattress brands and shops

In October 2023, we asked 3,530 Which? members who had bought a mattress in the past five years to tell us about their experiences. To work out customer scores for mattress brands, we asked what brand of mattress members owned, whether they were satisfied with it and whether they'd recommend it to friends or family. 

We also asked members how they'd rate mattress shops for quality of advice, range of mattresses, value for money and ease of arranging delivery.
