"Your mattress is your sanctuary" according to Eve Sleep, so you want to make sure you're comfy considering how much time we spend asleep - about one-third of our lives are spent sleeping. There are three foam layers to support your body while you sleep, and the memory foam isolates movement so you won't be woken up by your partner tossing and turning. You also get 100 nights to test it out, and if you're not satisfied, send it back. Support: Medium/Firm Recommended for: Back sleepers, front and side sleepers Mattress depth: 24cm
With 2,000 pocket springs in each mattress, you can choose between two firmness levels, and the price is 50 per cent less than on the high street. The mattress is made with breathable viscose damask, giving you a smooth and cool sleeping surface. You can trial this mattress for up to 100 nights and return it if it doesn't suit you (you must try it for a minimum of 30 nights). Support: Firm Recommended for: Back sleepers and side sleepers Mattress depth: 28cm
You can trial this mattress for a whole YEAR and send it back if you're not 100 per cent convinced, plus the warranty is 'forever' (well, as long as you own the mattress). These are real bonuses when it comes to choosing a mattress, as you really have to make sure you're happy with it - and an extra bonus when you're buying online without trying it out in the shop.

Mattress depth: 25cm
Lay back on 2,500 springs for a great night's sleep, with five layers to regulate your temperature and keep you cool all night.

Support: Medium Recommended for: Back sleepers, front and side sleepers Mattress depth: 25cm
We were pleasantly surprised that Wayfair offer a 100-night trial on their mattress too. Not much more than £100 for an open-coil double mattress; its firmness is 'medium' meaning average support for your back. Support: Medium Recommended for: Back sleepers, front sleepers Mattress depth: 18cm
Less than £200 for this anti-allergy mattress, which has air vents to keep you cool. It's double-sided so you can flip it regularly to keep it in top condition. Comes with a five-year guarantee, although there are no refunds or sending it back unlike many others on our list. Support: Medium/Firm Recommended for: Back sleepers, front sleepers Mattress depth: 20cm

Lots of brands offer trials, so you don't have to commit until you're 100 per cent happy with your purchase. Check the T&Cs of the mattresses you look at - some offer 100 days, some offer 365 days (and some don't offer a trial at all - so do check). It's a good idea to try them out, especially as you haven't tested them in a shop at all.
If you do trial them at home, take advantage of the timescale - it can take a few weeks for your body to become accustomed to a new mattress, so it might take a while to really work out if it's right for you.
Popular mattress designs at the moment include memory foam, cooling layers made from breathable materials, or a combination of the two. Memory foam might not be best for you if you get hot in the night, as it can be too cosy for some - again, that's why a trial is so great.
How often should you replace your mattress?
The Sleep Council recommends that you replace your mattress every seven years, as this means it's had over 20,000 hours of wear and tear, plus it's played host to all the fluid and skin cells we lose while sleeping.
A lot of mattress brands offer up to 10-year guarantees so keep an eye on if it needs replacing and don't lose the receipt details!
How to keep your mattress in good condition
Using a mattress protector is a great basic way to keep it free from stains and washing it regularly will help keep your mattress fresh.
Flipping or turning your mattress regularly helps to wear it out evenly, ensuring your body is always supported in the right places. Let your mattress breathe! When changing your sheets, let your mattress air out for an hour or two.
Give your mattress a clean at least every six months. Start by gently vacuuming the surface with an upholstery attachment, getting into any nooks and crannies to clear up any dust. If there are any stains, a mixture of baking soda and water will do the trick, but ensure you check with your manufacturer's guidelines before applying anything.
