Which? memory foam mattress test uncovers Don't Buy to avoidWe also reveal the best mattresses of nine on test
15 June 2014
The latest Which? test of memory foam mattresses has revealed a mattress that was so poor that we rate it as a Don't Buy mattress you should avoid altogether.
Every mattress we review is put through a tough durability test, which involves rolling heavy barrels back and forth across it to simulate several years of use. During this test, the mattress developed a large tear in the middle of the foam which, as you can see from the picture to the right, made it unusable.
Which? mattress expert Matt Clear said: 'This was the worst mattress we've encountered in three years of testing, but there are plenty of better alternatives out there, including Best Buys for £400 or less.'

Ikea, John Lewis and M&S mattresses reviewed
The latest memory foam mattresses we tested included own-brand models from Ikea, John Lewis and Marks & Spencer, plus mattresses from specialists Dormeo, Myer's, Rest Assured, Sealy, Silentnight and Tempur.
None were quite good enough to be rated as Best Buys, but some came close and are definitely worth considering, including one 'very durable' mattress that will 'stay in good condition and last for years to come.'
Memory foam mattresses aren't for everyone, though. Find out more about memory foam mattresses so you can decide if they're the best option for you.
Best mattress topper brands
Can’t stretch to a new mattress, or don’t want to replace the one you’ve got? A mattress topper could help make your mattress more comfortable for a relatively small cost.
A mattress topper sits on top of a mattress, offering a layer of memory foam or extra padding, and can be bought for as little as £10 – although most cost more than that.
When we surveyed 6,437 Which? members in January 2014, half of those using a mattress topper said that it made their mattress a little more comfortable, and almost a third said that it made their mattress much more comfortable.
