With a plush, cushioning pillow top, and orthopaedic, highly supportive pocket springs, the Premium Memory Hybrid Mattress is ready to offer you the proper night's sleep you've been dreaming of. Orthopaedic pocket springs target key areas of the body High tensile steel pocket springs are housed in individual fabric pockets, allowing them to move independently - a bit like piano keys - to adapt to your changes in weight distribution (your movement) throughout the night. This adaptability allows them to target intense support to key areas of your body, especially your shoulders and hips, which in turn helps to keep your spine aligned to reduce back aches and pains. A cooler, fresher night's sleep free from overheating To help keep you at the optimal sleeping temperature, a generous layer of Cool Gel Memory Foam actively draws heat away from the body for a fresher, cooler sleeping experience. This memory foam also gently moulds to your unique body shape, offering personalised pressure relief that helps to relieve tension at every point of contact. A plush pillow top layer acts as a built-in mattress topper, plumped with Comfort Foam layers which provide even more cushioning pressure relief. An undisturbed night's sleep and a fuller sleep surface Reinforced edges thanks to an outer layer of firmer pocket springs allow you to enjoy the full surface of the mattress without worrying about side-sagging. Maintaining the structure of the mattress and enhancing its durability, this 'no roll together' technology also gives you and your partner personalised sleeping zones, so you don't end up rolling towards the middle of the bed by accident.
