ViscoGel reacts quickly to body heat, allowing it to contour to your individual body shape to enhance circulation and help alleviate any aches and pains. ViscoGel’s unique heat transference technology features super-conductive Graphene, one of the latest materials to be used in mattress design. Graphene creates a pathway for body heat, allowing it to dissipate naturally as you rest, regardless of how much you move during sleep. This creates a more comfortable and ambient sleeping environment, night after night. ViscoGel Benefits: Disperses body heat and moisture Improved sleep hygiene Helps alleviate aches and pains Quality assurance and longevity Complies with strict UK fire regulations Combination of 3000 Pocket Springs – Why Pocket Spring? Since pocket springs work independently from each other, pocket sprung mattresses support your body weight to a greater degree than an open coil spring system (also known as standard sprung). This body-reactive design can help you to feel more comfortable and well-supported as you sleep, offering even pressure distribution to reduce the risk of pressure point build-up. Micro pockets offer an advantage when they are used to compensate for the deeper comfort layers where large quantities of fibres are used. Because pocket springs are designed in a way where they are slightly compressed, they tend to retain their comfort and height much longer than fibres. This means they can add extra durability to your mattress. Allowing it to perform at its best for longer. Density/Firmness Rating – What's Best for You? Each type of mattress varies by comfort grade, from soft to very firm. Our density ratings (provided by the manufacturer) are to be used as a guide. Every comfort grade has its advantages and the right one for you depends on your personal preferences but also your favoured sleeping position. The Roseland Sleep Halo Pocket 3000 mattress is rated as Medium. Soft Offers the least resistance, providing a gentle support base, contouring to your natural body shape. Perfect for side sleepers.
