Diamond Support Memory Foam Open Coil Mattress
“Refund was approved and back in my account the same day.” - Deliver+ customer
This diamond-quilted mattress is designed to deliver dependable comfort, durability, and long-lasting support, making it an excellent choice for everyday use. Built with a durable 13.5 gauge open coil spring system—one of the most trusted spring units worldwide—it provides consistent support and even weight distribution across the entire sleeping surface. A layer of memory foam enhances comfort by gently contouring to the body’s natural shape, helping relieve pressure points while promoting healthy circulation and full head-to-toe support. The mattress features a vertically stitched border that strengthens the edges and helps it maintain its shape over time, while also giving it a neat and contemporary appearance. Generous layers of high-quality polyester padding add extra comfort and support, and the diamond-quilted finish in a soft knitted fabric cover improves durability and sleeping comfort. Hypo-allergenic materials help create a cleaner and healthier sleep, making the mattress suitable for allergy-sensitive sleepers. With an approximate depth of 9–10 inches, this mattress is suitable for all standard bed bases and fully compliant with UK fire safety regulations. Proudly manufactured in the UK and supplied direct from the manufacturer, some sizes may be delivered boxed for easier handling. Please allow 24–48 hours after opening for the mattress to fully expand and reach its optimal height and performance.
Small Single W 75 cm x L 190 cm, Single W 90 cm x L 190 cm, Small Double W 120 cm x L 190 cm, Double W 135 cm x L 190 cm, King W 150 cm x L 200 cm, Super King W 180 cm x L 200 cm. Dry Clean Only
