This 23cm medium hybrid mattress delivers the best of both worlds: the body-cradling comfort of memory foam and the responsive support of pocket springs. Designed to suit all sleep positions, it helps keep your spine naturally aligned while reducing pressure on hips and shoulders. The breathable 3D knit cover enhances airflow and wicks away moisture for a cooler night's sleep. Compressed and rolled into a box for easy delivery, it is compatible with solid platform beds, sprung divans, and slatted bed frames — simply unbox, unroll, and allow up to 72 hours to fully expand.
