The SmartSleep Posture 140 Mattress is made from quality high density foam which has a medium feel and offers a good level of support from edge to edge, maximising the sleeping surface. The traditional quilted Damask cover gives this mattress added comfort. At 14cm deep, this mattress is lighter in weight and doesn’t require turning over – an advantage to those wanting to avoid heavy lifting. It is also ideal for top bunks and high sleepers as it conforms to safety height guidelines. The mattress cover boasts the added benefit of Hycare&reg technology – an antimicrobial treatment which inhibits house dust mites, helping to improve the cleanliness of the mattress. This mattress is made to standard in the UK and comes with a full 10 year structural guarantee for your peace of mind. It is delivered vacuum packed and rolled for easy transportation. Once unpacked, just give the mattress a few hours to fully expand.
