Non-sprung & presenting a soft to medium support, the value Pack 4ft mattress blends a base layer of premium reflex foam, topped off with a layer of visco elastic memory foam. Temperature sensitive, memory foam softens with body heat contact, reduce pressure points & mould itself to your body contours, resulting in better blood circulation. Its reflex foam also eliminates pressure points by displacing air bubbles in the foam sideways when pressure is applied & returning to its original shape when the pressure is removed. Most memory foam mattresses are one-sided & do not need to be flipped over, however, the value pack is designed to be dual-sided & can be used on both sides. As the memory foam is only on one side, the feel on each side may vary. Vacuum packed in a roll, the value pack is ideal where access to the bedroom is limited. Once opened, it fills out to its full & permanent size within a couple of hours.
