Do you sleep on your side? Then congratulations! This sleeping position is generally regarded as beneficial by doctors, because it keeps your airways open, reducing snoring and the risk of sleep disorders such as sleep apnea. But those health gains might be lost if you're sleeping on the wrong mattress. If you're a combination sleeper, head to our general best mattress guide, but if not this article is dedicated to focusing on the best mattresses for side sleepers specifically.

The wrong kind of mattress for you is one that's too firm. That means there won't be enough give to let your hips and shoulders sink into the mattress, and your spine won't be correctly aligned while you sleep. Instead you need a softer mattress that still provides a good level of support, to keep your spine aligned correctly. 

Overall, our best mattress for side sleepers overall is the Tempur Cloud Elite 25, due to its supportive base layer, sinkingly soft upper layer, and low-level maintenance. However, all of the mattresses on this list have a lot to offer side sleepers, and one of them may be more suited to your specific needs.

Tempur's Cloud Elite 25 is no ordinary memory foam mattress. It uses a patented,  extra-soft type of foam called Tempur-Pedic, which is both denser and softer than ordinary memory foam, so does an excellent job of moulding to your shape. Beneath this lies a firm layer to provide solid support to keep you in proper alignment as you sleep. Finally, the removable cover can also be washed at up to 60 degrees to keep things feeling fresh. It all adds up to a luxurious and comfortable sleeping experience, making this 25cm (10in) thick mattress our favourite pick for side sleepers overall. Note, these mattresses do have a 'sinking in' feel, that won't appeal to everyone – head to our Tempur mattress review for more info.

Its zoned support also means that you won’t go flying if your partner turns over in the night, keeping everyone happily asleep.

In total, this 27cm (10.5in) thick, medium-soft mattress is a great choice if you're a side sleeper who doesn't get on with either conventional foam or conventional springs.
