This Good Nite orthopaedic foam mattress features a 16 cm thickness and professional 3‑zone design, built from high-quality high-resilience sponge to deliver balanced cushioning and firm support. It contours naturally to your body shape, evenly dispersing body weight and relieving pressure on sore joints and tight muscles, making it a great choice for all sleeping positions. Encased in a soft, breathable polyester fabric cover, the mattress promotes steady airflow and prevents heat build-up while you sleep. The zippered outer cover is fully removable and washable for simple daily maintenance. Thanks to excellent motion isolation, movement on one side will not easily transfer across the mattress, so you will not be woken by your partner shifting during the night. The mattress complies with UK safety requirements and contains no harsh chemicals or common allergens, safe enough for children and those with sensitive skin. It is available in four popular UK bed sizes: Single, Small Double, Double and King. It arrives compressed and rolled inside a compact box for easier handling and delivery.
