An extra firm mattress is a perfect solution for those who dream of a higher-density sleeping space that gives added support and comfort. If you need extra support for your back at night, an extra firm mattress from British Beds Direct is the answer you’re looking for. As there is less give in an extra firm mattress, you’ll have good posture whilst you sleep as your spine is less likely to curve. This extra stability also means the mattress doesn’t move much if you toss and turn. Available in various sizes, ranging from single to super king.
