You could be wasting thousands on the wrong mattress. A good mattress can improve your sleep, and with so many options on the market, it's hard to know where to start. The best mattresses of 2026 promise to deliver comfort, support, and a great night's sleep. But with so many brands and models to choose from, it can be overwhelming. That's why we tested 14 bed-in-a-box mattresses to help you find the best one for you.

Our testing process involved a panel of family members who spent at least two weeks sleeping on each mattress. We rated each mattress on factors such as firmness, comfort, and motion isolation. We also considered the materials used, the trial period, and the warranty. They're all important factors to consider when choosing a mattress.

The Otty Original Hybrid Double was our top pick, with an outstanding balance of support, cushioning, and breathability. It's a firm but cosy mattress that helped our testers sleep fantastically from the first night. The Simba Hybrid Pro Double was our pick for couples, with a wonderfully comfy surface that makes you feel like you're sleeping on a cloud.

For those on a budget, the Ikea Valevåg Double is a great option. It's a pocket-sprung mattress that's wonderfully breathable and cooled down faster than any other mattress in our temperature-control test. This makes it a great choice for people who tend to sleep hot. It's also affordable, which is a bonus for those who don't want to spend a lot.

If you're looking for a sustainable option, the Woolroom Standen Wool Double is a great choice. It's made from natural materials, including wool, silk, and cotton, and has a 15-year warranty. This makes it a great choice for people who care about the environment and want a mattress that will last.

When choosing a mattress, it's essential to consider your sleeping position, body type, and personal preferences. Side sleepers need a softer mattress to cushion their pressure points. Back sleepers, on the other hand, need a medium-firm mattress to keep their spine aligned. Stomach sleepers need a firmer mattress to keep their hips and shoulders in alignment. They're all different, so it's worth considering what you need.

It's also important to consider the materials used in the mattress. Look for natural materials, such as wool and cotton, which are breathable and durable. They're better for you and the environment than harsh chemicals and dyes, which can be bad for your health. You don't want to be breathing in chemicals all night, so it's worth avoiding them.

Finally, don't forget to check the trial period and warranty. A good mattress should have a trial period of at least 100 nights and a warranty of at least 10 years. This gives you time to test it out and ensures that it will last. You won't have to worry about it breaking down after a few years, which is a relief.

By considering these factors and doing your research, you can find the perfect mattress for you and wake up feeling refreshed and rejuvenated. You'll be glad you took the time to choose a good mattress, and you'll sleep better at night.

'A good mattress can improve your sleep, and with so many options on the market, it's hard to know where to start,' says Jane Hoskyn, a consumer journalist who tested the mattresses. She knows what she's talking about, and her opinion is worth considering.

Side sleepers need a softer mattress, while back sleepers need a medium-firm mattress, and stomach sleepers need a firmer mattress. It's worth considering what you need, and choosing a mattress that's right for you. Look for natural materials, such as wool and cotton, and avoid harsh chemicals and dyes. They're not good for you or the environment, and you don't need them in your mattress. Check the trial period and warranty, with a minimum of 100 nights and 10 years, respectively.

This will give you peace of mind, and ensure that you're getting a good mattress.
