For those who suffer from back pain, the extra layer of Ortho Comfort Foam is engineered to ease joint pain and keep your spine in a neutral position to prevent pressure points from ruining your night�s sleep. The mattress has a medium firmness rating.With a five-year guarantee, you can be sure that your MLILY Bamboo Plus Ortho mattress will provide you with hundreds of nights of blissful sleep. The use of Flex Ortho foam provides that extra layer of cushioned support, while the dense core support foam works in harmony with the sprung centre to create a responsive and supremely comfortable mattress.For those who prefer a cooler sleeping environment, the MLILY Bamboo Plus Ortho mattress incorporates MLILY�s unique Air-Flow Bamboo Charcoal memory foam layer, which regulates temperature and moisture as well as minimising odours for a fresher, more comfortable night�s sleep. The foam adapts to the body�s micro-pressure points, preventing aches and pains while keeping you cooler and more comfortable all night long.At the core of this complex and technologically advanced orthopaedic mattress is a matrix of 800 individually pocketed springs, all working individually to respond to every movement you make. This matrix distributes movement evenly, minimising the possibility that your night-time wriggles will disturb your partner by dissipating the vibrations.Nothing ruins the feel of a good mattress like a saggy side! Not only does it reduce the sleeping area you can use, but it will eventually damage the integrity of the mattress, shortening its lifespan. The MLILY Bamboo Plus Ortho mattress has a strengthened border that�s breathable and includes specially mounted F-joints to provide that all-important strengthening right across the width and length of the mattress. No more sagging!
