A thick layer of high density reflex foam is used to act as the support mechanism in this mattress. Unlike memory foam, reflex foam does not mould to your body as much and bounces back fairly quickly. Due to these special properties, it is a fairly firm material which will provide a support to a mattress to ensure your weight is distributed properly. A spring system is used to provide support alongside a bouncy comfort which materials such as memory foam cannot do alone. Each spring is individually wrapped which allows each spring to react independently from one another. This allows for two people to sleep together without affecting one another when moving. FEATURES:• Material : Memory Foam• 2cm of high density reflex foam• Individually wrapped pocket spring system• Reflex foam boundary around springs• 18cm Thickness• Orthopedic mattress• Ecological• Sanitised fabric• Hypoallergenic• Anti dustmite features• Made to British Standards/Regulations• Fantastic-value, only at Elegant Furniture UK DIMENSIONS:• Mattress Size : Double Mattress
