The breathable knitted fabric cover promotes optimal airflow and temperature regulation, helping you maintain a comfortable sleeping temperature throughout the night. With high-resilience sponge material that maintains its shape over time, this mattress offers consistent support and durability. With a generous 30cm height profile, it provides ample space and substantial comfort for a restful night's sleep. The hybrid construction adapts to your body contours whilst delivering the support you need for proper spinal alignment. StowGrain Mattress Size: Double (4'6)
