Let our list of the best mattresses on the market, from memory foam to pocket springs, latex to sheep’s wool, help you on your quest for the perfect night’s rest

A good night’s sleep can be a transformative thing. When you get up on the right side of the bed, the sun seems to shine more brightly, the birds sing more sweetly, and there’s an unmistakable spring in our step. That's why finding the best mattress to sleep better is essential.

That’s also why experts say (and we agree) that finding the right mattress is so important. With all the different types out there, it can seem a bit of a minefield, but we’ve put together some bite-sized advice to help you pick the best mattress for your needs, and a round-up of our favourites on the market right now, to help.

Many of us will have tried a memory foam mattress in the past, and it’s easy to see why they’re so popular. They tend to be on the firm side, which is good for anyone who needs a little extra support, but also mould to the shape of the sleeper, so they’re an easy way to a perfectly tailored night’s sleep for side sleepers or scoliosis sufferers who might not get on with traditional spring mattresses.

However, as sinking into the foam insulates your body, it’s not only harder to regain a comfortable position if you move during the night, it can also heat you up considerably, which many people understandably don’t like.

Latex foam mattresses, while typically more expensive, are a good antidote to this. Like memory foam, they adapt to the shape of your body, but spring back more quickly, so they’re good for serial fidgeters, and typically have an added cooling layer. Being hypoallergenic and antimicrobial, they’re also an excellent pick if you suffer from asthma or a dust mite allergy, so you may find it’s worth paying the extra to breathe, and rest, easy.

Finally, there are the springs. Pocket springs are the new standard for non-foam mattresses, as unlike traditional open coil or open spring mattresses, they offer zoned support that minimises the risk of sinking or rolling into your sleeping partner.

Our number one mattress is supportive and adaptive for all kinds of sleepers, combining the firmness of memory foam with a breathable and cooling top layer that acts as a remedy to the usual over-warming that comes with it. As such this is the best mattress for combination sleepers.

Good for those with joint, neck or back pain, as well as back, stomach and side sleepers, it really is a fantastic all-rounder. However, if for any reason you don’t get on with it, Casper operate a 100-night trial, so there’s no risk. 

The zoned support system in the Casper mattress means hips and shoulders are treated differently for ideal alignment and comfort. Thanks to four layers of premium quality foam there's lots of support for a comfy alignment but also enough breathability to make sure you're happy no matter the temperature. 

The durability of the mattress, thanks to a strengthening base layer, will make this go the distance while the pressure-relief from pressure point support will make you never want to change. The high airflow makes this perfect for anyone who overheats but also needs the support of foam.
