The Coolflex ProPosture™ Ortho Foam mattress has been created with superior support in mind. However, while it's ideal for those who suffer from back pain, there's no compromise on comfort. The ProPosture™ Ortho Foam used in its manufacture is as reactive and adaptive as Coolflex's best memory foams, cushioning and contouring the whole body while keeping the spine perfectly aligned. It's a superior mattress for those who find it difficult to sleep due to muscular aches and pains.

The Ultimate in Spinal Support

Research has found that a poorly-constructed mattress can not only compound back pain but also cause it. The Coolflex ProPosture™ Ortho Foam mattress tackles the causes and symptoms of these ailments using a visco-elastic material to offer full-body support. Temperature-sensitive, it moulds to and supports the body's warmer parts, helping cushion joints and take the weight from pressure points, such as the shoulders, hips, and knees. By keeping the spine in perfect alignment, the mattress promotes blood flow to the inflamed or painful areas of the back, allowing the body's inflammatory processes to get to work.

Zero Motion Transfer

As anyone who suffers from back pain will tell you, the nocturnal wrigglings of their sleeping partner can be painful and frustrating. Because the Coolflex ProPosture™ Ortho Foam mattress is made from orthopaedic memory foam, it completely removes the transfer of motion between bedfellows. As an additional benefit, ProPosture™ Ortho Foam can help reduce your and your partner’s need to toss and turn by up to 80%. With a mattress this comfortable, you’ll find your perfect sleeping position in seconds.

Hypoallergenic and Antimicrobial

The foam used in the Coolflex ProPosture™ Ortho Foam Mattress is hypoallergenic and antimicrobial, eliminating dust mites, fungal spores, mould, and mildew. In addition to keeping the mattress fresh and hygienic, it also offers the perfect sleeping conditions for those who react to environmental allergens.

In addition to peerless levels of comfort and support, the Coolflex ProPosture™ Ortho Foam mattress helps the sleeper achieve the ideal temperature for a refreshing night's sleep. Using a removable AirFlo™ Cover during the warmer months, the mattress is transformed into a breathable sleeping surface with outstanding moisture-wicking properties. Moving moisture away from the body helps to create a soothing and cooling effect. During winter, the mattress' dense structure traps body heat, leaving the sleeper snug and warm. This is an indulgent and supportive mattress at any time of year.


ProPosture™ Ortho Support Foam

The firmest of our mattress fillings, ProPosture™ Ortho Support Foam is an extra-firm support layer. This firm sleep surface conforms to each part of your body, giving great orthopaedic support, pressure-relief and correct spinal alignment. It supports you right to the very edge of the mattress, too, meaning no 'roll-off'!

20cm Depth

This mattress is approximately 20cm deep.

Extra Firm Support

The firmest level of support. Also known as orthopaedic.

Removeable AirFlo™ Cover

Our AirFlo™ Cover, with MoistureControl™ wicking technology, helps regulate your bodies temperature throughout the night as you sleep to stop you getting hot and clammy. It also features zipped sides which enable it to be removed for easy cleaning.

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 and are usually ready to sleep on within 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.


Being hypoallergenic, this is the perfect item for allergy sufferers - or anyone looking for a healthy night's sleep.
