Choosing the right mattress is one of the biggest homeware decisions you'll make - you spend so much time sleeping that a supportive, comfortable mattress is vital.

There are loads of mattress brands available online these days, meaning you no longer have to set aside a whole day to trawl the shops trying them out, desperately trying not to get your shoes on them, feeling ever-so awkward pretending to sleep in front of the always-too-keen salesperson.

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.

Dunelm Fogarty Just Right Orthopaedic Open Coil Mattress
8 of 9

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.

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.
