What's the best comfort grade for your sleeping position?
Soft mattresses are generally better for side sleepers, as they respond to pressure points and help to keep your spine straight. For front and back sleepers, a firmer comfort grade is best, as this will keep your body aligned in a natural position.

Don't think you'll be sacrificing a good night’s sleep with this type of double bed mattress though, as they still reach our high standards for mattresses. They're available in a range of comfort grades, so no matter your sleeping position, you can get a good night's sleep on a budget. For more, check out our cheap mattresses under £400.
ActiGel mattresses respond to your body heat throughout the night. The gel layer helps to ensure you don't get too hot or too cold. These mattresses also offer cuddlesome comfort, moulding to your individual shape and keeping your spine aligned throughout the night.
Double mattresses are very popular with couples as this is the minimum size for two people to sleep comfortably. A double pocket sprung mattress minimises the feeling of your partner tossing and turning in the night, as the springs are individually wrapped which limits the amount of movement in the rest of the mattress.
Remember, our 100-Night Sleep Guarantee means you can swap your mattress for another if it doesn’t feel quite right (T& Cs apply). If you’d like any further advice on finding the best double mattress that suits you, take a look at our mattress and bed buying guides.
