Investing in one of the best mattresses can make the difference between a restless night of tossing and turning and waking up feeling refreshed and ready to tackle the day. While any best mattress round-up worth its micro-springs will cover temperature regulation, motion isolation, edge support, and breathability, we’ve narrowed down our tried-and-tested favourites to help you find the perfect match for your unique sleep style.
There are countless reasons why ditching your old mattress in favour of the right one could elevate the quality of your kip tenfold (from relieving your joints of pressure to ensuring you wake up less, move about less and feel less disturbed by your partner). And since getting a good night’s sleep is one of the most important things we can do for our physical and mental health, investing in one of the best mattresses 2025 has to offer is something you shouldn’t sleep on.
That said, shopping for a new mattress can be a bit daunting. A mattress is a big investment, and there’s lots to consider – from firmness levels to your sleeping style, preferred price tag and much, much more. Unfortunately, one size does not fit all.

What is the best mattress to buy in 2025
Choosing the “best mattress” is highly subjective and depends on your individual needs. Right now, we’re big fans of the Emma Hybrid Premium Mattress, but we’d also recommend the REM-Fit® 400 Hybrid Mattress and Simba’s Hybrid range. These three brands offer a variety of mattresses, including some of the best options for side sleepers and back pain relief, all at different price points to suit most budgets. While many high-quality mattresses come with sleep trials, returning one can be a hassle — especially since they’re vacuum-packed and tricky to repack. That’s why it’s crucial to do your research beforehand to ensure you’re making the right choice for the long haul.
How did we test the best mattresses?
When testing the mattresses in this edit, the GLAMOUR team assessed each one by spending a minimum of 30 days sleeping on them in their own homes. Adhering to our testing criteria, we all assessed on firmness, comfort, support, motion isolation, cost, and sustainability credentials, in addition to considering factors such as delivery convenience and impact on sleep quality. We’ve had hands-on testing experience both at home and in store showrooms and while we’ve tested over 21 mattresses, these final 13 get the GLAMOUR seal of approval. Ahead, find discover comprehensive reviews accompanied by our tester’s insights into the strengths and weaknesses of each mattress so you can make an informed decision before investing.
How often should you replace a mattress and how do you know when to change it?
According to the Sleep Council, you should change your mattress once every seven years, when you start to notice that you sleep better in other beds or when you wake up with aches and pains. Particularly if it didn’t cost you very much. Luxury mattresses like those crafted by Simba or Brook and Wilde might last you longer – up to a decade. And you can help them last for longer with a mattress protector.
What are the best mattress companies in the UK and can you order a mattress online?
Yes! Sleep-tech companies like Emma, Simba, and Nectar, have made the process simple with their “mattress in a box” offerings, and according to the National Bed Federation, bed-in-a-box mattresses now make up around 25% (!) of the industry market share. Most bed in a box mattresses come with an 100 night trial, a ten-year warranty and can be delivered direct to your door. Elsewhere, brands like Silentnight, Sealy and Dormeo are offering buyers a whole host of equally high-quality non-rolled options, from pocket memory mattresses to ortho mattresses, so don’t overlook these not-in-a-box brands, either.
