Our Ultra 40 HD Orthopaedic luxury mattresses are made using a combination of our highest-grade ultra-dense 40 HD blue foam and our innovative and responsive memory foam. Our ultra-dense foam, constructed using a close cell formation, produces one of the firmest mattresses available on the market, ensuring maximum support throughout the night and gently supporting your back and joints to minimise aches and pains. The extra-firm support distributes your body weight to alleviate stress on the spine, relieving painful pressure points and helping to maintain the natural alignment of your spine. Added to this is a top layer of our advanced memory foam, which reacts to your body heat, cleverly moulding to your unique body shape to help distribute your weight evenly across the mattress. This provides optimal support and relief to your pressure points to give you the most comfortable sleep possible. These mattresses are particularly helpful for people with back aches and pains, as the soft surface helps keep your spine perfectly aligned. Coupled up with our multi-layered quilted cover, constructed using 4 different layers, a flexible fine mesh breathable fabric that allows trapped body heat within the foam to escape, aiding in cooling the body, a layer of generously padded soft micro fibres to enhance the overall softness and comfort provided by the mattress, a layer of micro mesh hi-flow fabric used to quickly dispel any excess heat present and layered on the base with our moisture resistant base fabric, this weaved fabric allows trapped moisture within the mattress to escape but won’t allow moisture to penetrate back in, this mattress is perfect for those looking for a genuine luxury ultra-firm orthopaedic product with the added advantage of memory foam. Comes with a unique 3D removable zip cover. Note: The outer cover design and colour may vary slightly from the picture, but the material and specifications will be the same.

I’m extremely pleased with this mattress. I’ve always slept on extra-firm mattresses, so I was slightly concerned that the memory foam layer on top might make it too soft. However, it exceeded my expectations. It remains very firm and offers excellent back support, while the subtle soft layer on top adds comfort. Overall, I’m very happy with it and would definitely say it lives up to the extra-firm standard.. Heller-kiss. Stevenage, GB. Fri Jan 30 2026
