The Relyon Comfort Pure 1000 offers responsive support through the use of 1000 springs, each of which is mounted in a fabric pocket. This innovative spring system, along with the mattress� soft and durable filling and breathable knitted cover, relieves pressure on muscles and joints and makes for a more comfortable sleep. The inclusion of individual personal sleeping zones also means you won�t be woken if your partner moves during the night.The mattress also benefits from a 100% natural, probiotic fabric treatment that protects against allergens, bacteria, and odours. This ensures your mattress remains free of contaminants and improves the quality of sleep if you suffer from allergies. Additional comfort layers are included between the mattress cover and springs for greater cushioning and a more comfy feel.Each of the 1000 springs used within the mattress is packed into its own fabric pocket. As they�re able to move separately, they react to shifts in pressure and weight, providing more targeted support.Over time, many mattresses suffer from sagging at the sides. Not only does this shorten the mattress� expected lifespan, but it also limits the space you have to stretch out. To counter this problem, the Relyon Comfort Pure 1000 features firmer springs along the sides. With strengthened sides, you enjoy greater usable space and the mattress retains its shape and strength for years to come.Designed so you never need to flip it, the one-sided Relyon Comfort Pure 1000 Mattress is an excellent choice if you or a family member struggles to turn your current mattress. Rather than flipping it, the mattress should be rotated, head to tail, on a regular basis. To assist with this, stitched handles are attached to the side of the mattress.
