For an expert level of orthopaedic support, the Super Firm Foam Mattress is extra firm - perfect for those who need specialist spinal support or those who prefer a very firm sleep surface!
Recommended for those who suffer from regular back aches and pains, the Super Firm Foam Mattress helps to promote a better sleeping posture for both front and back sleepers. Deep Reflex Foam gently contours your body without compromising the extra firm feel of the mattress, resulting in personalised pressure relief across your entire body. Helping to keep your shoulders and hips in line with your spine, this level of support is also ideal for particularly heavy people, preventing you from sinking uncomfortably into the mattress surface.
Innovative Reflex Foam works similarly to memory foam, while encouraging more air circulation to prevent overheating and encourage an ideal sleeping temperature. This is complemented by a soft-knit, highly breathable mattress cover, which is also removable and machine-washable for your convenience. Arriving rolled and boxed for easy transportation, you can soon have your extra firm mattress set up and ready for a night of orthopaedic support.

Rated Excellent
This mattress is amazing. Very firm and comfortable and a very good price compared to other extra firm mattresses I looked at. The delivery slot was very misleading though. We waited the whole day for it.
