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!
Specialist support for those with regular back problems
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.
Highly breathable and refreshing, with a removable cover
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.

Reflex Foam
Reflex Foam conforms to the shape of your body, offering a comfortable night's sleep, with tailored support to help improve your spinal alignment and posture.
20cm Depth
This mattress is approximately 20cm deep.
Machine Washable Cover
Highly breathable and fresh, this cover can easily be removed and popped into the washing machine to maintain a clean, odour-free environment.
Orthopaedic Support
Designed to offer a firmer sleep surface, providing targeted support for your back and joints.
No Need To Turn
A single-sided mattress which does not need to be turned/flipped. One-sided mattresses should, however, be rotated head to toe regularly.
Vacuum Packed & Rolled
Rolled mattresses have the advantage of being easy to transport, especially to upstairs bedrooms. When unrolled, they expand fully over time, usually being comfortable enough to sleep on after 48 hours.
No Roll Together
Individual personal sleeping zones mean that you won't be disturbed if your partner rolls or moves, as you won't feel their motion. There's also no tendency to roll towards the middle of the mattress.
Pressure Relieving
This type of mattress gives maximum pressure relief, allowing your body weight to spread across it evenly. This ultimately means less tossing and turning throughout the night and a more relaxing and restful sleep.
Hypoallergenic
Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.
Vegan Friendly
This product is made from materials that are 100% free from animal by-products.
Made in the UK
This item has been manufactured in the UK.

Customer Review Summary
Customers generally appreciate the mattress for its impressive comfort and robust support, frequently mentioning significant improvements in their sleep quality. Many highlight the use of high-quality materials, which not only enhance durability but also contribute to a luxurious feel. However, some reviewers have noted that the mattress tends to be firmer than they expected, which may not suit everyone\'s preference but is often seen as beneficial for spinal alignment. Overall, this product is well-regarded for delivering a satisfying sleep experience while maintaining a strong emphasis on quality.
