Enjoy more room to rest with our king size mattress collection. Measuring approximately 150 x 200 cm, a UK king mattress provides generous sleeping space for couples and solo sleepers alike. Explore pocket sprung, memory foam and hybrid designs in a range of comfort levels for a beautifully inviting bed.
A king size mattress offers additional width and length compared with a standard double, creating more space to stretch out and settle comfortably. Its generous proportions make it a popular choice for main bedrooms and couples who appreciate greater personal sleeping space.
Pocket sprung king mattresses use individual springs to respond independently across the surface, helping to create balanced support. Memory foam designs gently contour around the body, while hybrid mattresses combine foam and springs for a layered blend of cushioning and responsiveness. Traditional open-coil options provide a familiar feel and accessible everyday comfort.
Firmness plays an important role in the overall experience. Softer mattresses offer deeper cushioning, medium designs provide a versatile balance, and firmer options create a more supportive surface. Mattress toppers and protectors can add another layer of comfort while helping to keep the bed feeling fresh.
Explore our king size mattresses to find a design suited to your preferred sleeping position and comfort level. Paired with a supportive king size bed frame and beautifully coordinated bedding, the right mattress creates an inviting foundation for restful nights.
