This luxury Memory Foam Sprung mattress has been designed with a super soft, deep quilted top panel to cushion the sleeper's body for a comfortable night's sleep. The mattress has been designed with a breathable quilted grey border which ventilates the mattress and keeps airflow flowing through the mattress, keeping it cool, fresh, and odour-free. With 8 comfort layers, it has a 1-inch deep layer of next generation open cell Memory Foam which shapes and moulds to the contours of the body, providing extra comfort and support. The open cell foam is designed to relieve pressure from building, helping those aches and pains in the lower back, hips, neck, and legs. Designed with a traditional European spring open coil unit, which distributes the weight evenly across the mattress, providing the sleeper with a medium soft comfort. The mattress is approximately 9 inches (23cm) deep. The mattress is single-sided; simply rotate every so often to keep it in pristine condition and enjoy long-lasting performance. It will be delivered vacuum-packed, rolled, and boxed. We do recommend once the mattress has been unpackaged, leaving the mattress for 24 to 48 hours to allow it to.
