Best Soft Mattresses
Discover the best soft mattresses in our buying guide.
Soft mattresses have a plush, luxurious feel, allowing you to sink into comfort at the end of a long day. But with so many options out there, deciding on the right one for you can feel tricky.
Not to worry though, as we’ve rounded up some of the best soft mattresses in the UK. Whether you’re after breathable materials, cooling features, or extra pressure relief, we’ll help you find a soft mattress to suit your needs.
What is a soft mattress?
A soft mattress is designed to gently compress under your body weight, providing a cushioned feel that makes it easier to drift off. If a cosy, cloud-like surface is at the top of your priority list, a soft mattress is likely ideal.
While firm mattresses offer full-body support and spinal alignment, soft mattresses shine when it comes to pressure relief – especially around the hips, shoulders, and lower back. This level of mattress firmness is typically recommended for side sleepers and those with a lighter build, however due to advancements in materials, you’ll now find soft mattresses to suit a wide range of sleepers.
What to look for when choosing a soft mattress
When shopping for the best soft or medium soft mattresses in the UK, there are a few things you’ll need to consider. First, while comfort is key, support is just as crucial, so make sure you look for something with a sturdy core. Whether it’s pocket springs or high-resilience foam, this will help support your body throughout the night.
Don’t forget to bear your sleeping position in mind too. Side sleepers generally benefit the most from soft mattresses, while back and combination sleepers might require something a little firmer.
Equally, if staying cool is a top priority, you might want to consider a soft mattress with cooling gel layers or breathable wool. These can help regulate your temperature and keep you comfortable as you snooze.
