Best overall

As one of our best mattress and best memory foam mattress picks, the Emma Mattress is a trusted bed-in-a-box for side sleepers, with the all-foam layers providing plenty of cushioning at the hips, knees and shoulders. In the middle is a Halo Memory Foam layer that adapts to your body shape to help align the posture, also adding enhanced pressure relief. And at the base is a super-durable foam layer with five cut-out zones that evenly distribute your body weight to further reduce the pressure on your posture.

As mentioned in our in-depth review, the Emma mattress has a softer feel to provide maximum cosiness for pressure points. While this means extra comfort, if you are heavier in weight or tend to swap position from side to front or back as you sleep, then you might require a little more firmness. If you’re not sure whether the Emma Mattress is a good fit for you, then take advantage of the generous 200-night trial to see for yourself.

Best for firmness options

If you're choosy about the firmness of your bed, the Brook + Wilde Elite is worth investigating as it comes in three comfort options: there's a firm (7 out of 10), medium (5) and soft (3), enabling you to choose a firmness level that goes best with your body type and sleep style. Our reviewer tested the firm option, however if you tend to sleep you your side you'll get on much better with the medium or soft version, which will give your shoulders and hips the cushioning they need while still providing plenty of support.

Thanks to two layers of springs – 2,000 mini springs and an extra 1,000 taller springs to provide even more bounce and push-back – the Elite is thoroughly breathable and won't leave you hot and bothered in the night. It also delivers superior edge support as well as very good motion isolation, which bodes well for co-sleepers who don't want to be disrupted by their partner's movements.

It's usually on offer with around 50% off, but bear in mind that it's made to order which means it'll take up to four weeks to arrive, You’ll have 200 nights to try it out, and there's a 10-year guarantee for peace of mind, and you'll also get free premium delivery and set-up included.

Best for heavier bodies

Just like the Emma Mattress, Nectar’s mattress also features in our best mattress and best memory foam mattress guides, for comfort, support and value for money.

As well as offering excellent pressure-point relief for side sleepers with Nectar’s own adaptive memory foam, the slightly firmer feel makes it a good option for heavier body weights. Co-sleepers will also benefit from the minimal motion transfer on offer. Other perks include decent temperature regulation, a seven-zone supportive base and a cosy-yet-cooling cover.

For the price, Nectar also provides a forever warranty, 365-night trial, and free delivery and returns. If you’re also looking to buy bedding including a duvet and pillows, then you can make even more savings when you buy these together with your mattress as a bundle.

How to choose the best mattress for side sleepers

If you are looking for a bed that keeps you comfortable while you sleep on your side, then it will need enough sinkage, cushioning and support to keep your spine aligned and in a healthy position for a good night’s rest.

The best mattress firmness for side sleepers is typically medium to medium-firm. Side sleepers of average weight generally benefit from a medium-firm bed with a little added softness, while those with a lighter build might need a touch more cushioning. For all side sleepers, a plush layer is crucial to keep the pressure points at the hips, knees, shoulders and head cushioned to avoid soreness and discomfort – something that can cause you to toss and turn.

Generally speaking, memory foam mattresses or hybrids with a cushioning or gel layer will deliver the softness you need and provide stability too. Choosing a medium-loft pillow will also help your head rest at the correct height and in alignment with the rest of your body. Check out our guide to the best pillow for sleeping to see our top picks.
