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 its airflow flowing through it, keeping it cool, fresh, and odor-free. With 8 comfort layers, designed with a 1” inch deep layer of next-generation open cell Memory Foam that shapes and molds 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. A traditional European spring open coil unit distributes the weight evenly across the mattress providing the sleeper with a medium soft comfort. The mattress is approximately 23cm deep. The mattress is single-sided simply rotate it every so often to keep it in pristine condition and enjoy the long-lasting performance. It will be delivered vacuum-packed, rolled, and boxed.
