Give your sleep a boost by sleeping on our hybrid mattress. StarNap is a hybrid memory foam pocket sprung mattress providing orthopaedic firm support. A balanced combination of next-generation memory foam, high density PU comfort foam and up to 1000 individually wrapped pocket springs work in harmony with the 3D quilted PolyBlend knitted jacquard cover, proven to wick away moisture and dissipate body heat. The top layer of comfort foam is supported by adaptive memory foam, providing a cool and gentle surface with orthopaedic support. The foam layers are supported by high resilience pocket springs to maximise comfort and support, contributing to a better sleep all night, every night. This pocket springs and memory foam combination is less bouncy than traditional mattresses, providing excellent comfort without motion transfer. Designed for optimum adaptive comfort for any sleeping style or position, be it a back-sleeper, side-sleeper or front-sleeper, or anything in between. It may relieve pressure on your hips, back, neck and shoulders. Allowing 30 times greater air flow than traditional foam, 4th generation memory foam offers all the benefits of memory foam without the disadvantage of trapped heat. Mattress must be unpacked within 7 days of delivery and left in an airy room before use. Colder temperatures may extend the time needed to fully expand.
