One of the most technologically advanced and complex mattresses on the market delivers something superbly simple � a blissfully comfortable night�s sleep. A combination of layers of springs interspersed with foam layers of different densities are designed to provide orthopaedic levels of support. The use of Flex Comfort and Ortho Support foam helps to ease back pain and eliminate those painful aches and pressure points that can ruin a good night�s sleep, while the Core Support foam provides even more cushioning so you wake up feeling refreshed.The mattress comes with a 5-year guarantee for complete peace of mind, and is single sided so there is no need to flip and turn. However, we do recommend that you regularly rotate the mattress from head to toe to avoid dips and lumps.At the very heart of the MLILY Bamboo Plus Serene mattress is a complex matrix of 2500 individually pocketed springs. These Ortho Firm springs are custom made to really raise the support levels, giving this mattress its medium firmness rating and banishing bad backs, aches and pains. However, just to give you that little bit extra comfort and support, there�s also a second layer of 2000 Adapt Mini Springs, which individually adjust and respond to your body�s movement, easing joint pain and helping you get a deeper, more restful night�s sleep. It may only be 2cm deep, but that layer of Mini Springs makes the MLILY Bamboo Plus Serene a very special and very comfortable mattress!There�s nothing worse than getting too hot when you�re in bed � it can ruin a good night�s sleep. MLILY has designed a special Nanocool Ice fabric that�s specially crafted to stay cool to the touch all night long. Combine that with a layer of Bamboo Charcoal memory foam that wicks away moisture and regulates temperature and you have that perfect cool sleeping environment, just what you need if you suffer from night sweats or hot flushes.Over time, unsupported or weak edges can start to sag, ruining the feel of a mattress and reducing its lifespan. MLILY has designed a special strengthening system that ensures constant and sustained firmness from the centre of the mattress all the way out to the edges. This Aero-Flex Support border has been aerodynamically designed to allow the mattress to breathe, while still supporting the edges using specially mounted F-joints. The result is a larger sleeping area, and no sagging!
