Which? reveals the best and worst mattress brands of 2018

New entries Casper, Dormeo and Simba face-off against high-street favourites John Lewis, Dreams, Silentnight and more

Our new mattress customer satisfaction survey has exposed a huge gap in quality between the best and worst mattress brands in the UK.

We asked 4,169 Which? members to rate 20 popular mattress brands – the top performer earned a stellar customer score of 87%. The worst could only manage 60% – 27 percentage points lower than the top brand – and failed to get more than two stars in any of the categories we asked about.

Online-only mattress brands, such as Casper and Simba, have boomed over the past few years. They feature in our survey results for the first time this year, as enough of our respondents own a mattress from one of these brands. But how do they fare against the biggest names in the business – John Lewis, Silentnight, Sealy, Dreams and Bensons for Beds?

See the full results by going to our new list of the best mattress brands for 2018.

Casper mattresses

New kid on the block Casper is a new entry to our annual list of the best mattress brands, along with Simba and Dormeo.

Casper is among a new class of mattress market disruptors. You order direct from its website, and your mattress is shipped straight to your door in a vacuum-packed box.

Of the Which? members we asked about their Casper mattress, 84% of them had bought their mattress within the past six months.

Casper has just one mattress in its range, and claims to have spent years developing the perfect formula. Like many bed-in-a-box brands, Casper also offers free shipping and returns as part of a 100-night trial period – so if you’re not happy with your mattress and decide to return it, Casper will collect it free of charge and offer a full refund.

John Lewis mattresses

More than 10% of the Which? members we surveyed own a John Lewis mattress – more than any other brand.

John Lewis sells a huge range of mattresses. Its own-brand collection ranges from traditional pocket-sprung and open-sprung models to modern memory-foam ones.

Its fair to say that John Lewis caters for the full spectrum of budgets. Its cheapest mattress is an open-sprung mattress in its Basics collection, which costs just £79 for a double. The most expensive is a luxurious, pocket-sprung, natural fibre mattress, which can cost up to £18,000.

Silentnight mattresses

With its mattresses sold in a wide variety of stores all over the country, as well as online, it’s no wonder Silentnight is the second-most popular brand among our members.

Silentnight sells a huge range of mattresses, all of which are reasonably priced. With memory foam, pocket-sprung, latex and foam mattresses available, all at a varying levels of firmness and breathability, there’s bound to be one that suits you.

Trying in-store vs trialling at home

As a rule, we recommend trying a few mattresses in-store before you buy, to help you decide which filling and level of firmness you like best. You might feel silly in the shop, but try to lie on them for at least 10 minutes, and in your normal sleeping position – it’s worth it for a great night’s sleep.

But there are some exceptions to this rule – what about online-only mattresses? Fortunately many of these bed-in-a-box mattresses – from brands such as Casper and Simba – offer trial periods as long as 101 nights. This will give you a much better impression than 10 minutes in a busy shop.

During this trial period you can return the mattress for a full refund – just make sure you read the terms and conditions, and use a mattress protector and a suitable bed base.

Our research into mattresses

To find the best mattresses and mattress brands, we use a combination of lab testing and customer surveys.

To assess how supportive, breathable, stable, and durable each mattress is, we put them through tough lab tests. But this only tells us so much about a mattress, as we can’t test for how comfortable a mattress is at the lab, as this is subjective.

That’s why we regularly run customer surveys – to capture key details that can’t be picked up in a lab, such as comfort and value for money.
