The Luxury 1000 is a hand crafted Highgrove ErgoSense mattress which is ergonomically designed to give a luxurious soft surface feel. By expertly combining luxury foam technology with an advanced spring system, it provides the complete balance of underlying support and ultimate comfort, giving you the perfect nights sleep. ErgoSense is not temperature sensitive and unlike Memory Foam, reacts immediately to body pressure to create a sense of weightlessness. It also reduces body pressure points to improve blood circulation, promoting restful sleep. ErgoSense is high performance and designed for long lasting comfort. The open cell structure of ErgoSense foam improves moisture dispersion and breathbility. For added convenience the deep layer of ErgoSense is used effectively in this single sided mattress so there is no need to flip, just rotate 180 degrees regularly. Comes with a 5 year warranty.
