The Amersham Deluxe has a 6 turn reactive pocket spring system. The more active turns in a single continuous pocket spring, the greater its ability to sense the exact comfort and support requirement of you and your partner. A single continuous pocket spring also creates a bellow-like effect that drives cool air around the mattress and facilitates greater hygiene. This extra breathability ensures better ventilation, helping to reduce moisture and maintain a comfortable body temperature for a healthy, relaxing and energising night’s sleep. Available as 2'6", 3', 4', 4'6", 5', and 6' sizes, with or without drawers, and as mattress only options.
