Sareer Matrah Ruby Gold Memory Foam Mattress in a Box - 3ft Single; The mattress is made up of a combination of reflex foam plus memory foam and is upholstered in a soft and luxurious knitted stretch fabric cover. The interior has a depth of 25cm, made up of a 5cm top layer of body-moulding memory foam, with a 20cm base layer of durable reflex foam. Both hypo-allergenic and temperature sensitive, memory foam is designed to react to body heat and mould itself to your natural sleeping position. Evenly distributing weight, memory foam reduces body pressure points.This helps to increase circulation and reduces tossing and turning. The reflex foam displaces air bubbles sideway when pressure is applied and returning to its original shape when the pressure is removed. Offering a comfortable and medium support, the Ruby Gold is an ideal choice if youre looking for a mattress thats not too hard and not too soft.
