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.
