King Size Mattresses

Hypnos offer a wide range of luxurious king size mattresses with a variety of features, including pillow top, no turn, wool, cotton, organic, or extra firm king size mattresses, which can be beneficial for back pain.

A king size mattress is longer than a standard double mattress, with a width of 5’0” (150cm) wide by 6’6” (200cm) long. They are ideal for master bedrooms or for people who want extra space in bed. All Hypnos mattresses can also be ordered to bespoke specifications, as well as zip and link to create a split king bed with two separate mattresses at different comfort levels.

Hypnos luxury king size mattresses are made with natural, sustainable British materials. Hand-made in the UK, each of our award-winning mattresses is assured by Hypnos' 10-year guarantee. Our master craftsmen continue to use traditional and time-honoured skills that have been passed down from generation to generation for 120 years to bring you the most comfortable beds in the world.
