Hypnia Mattress is a British bed-in-box brand born out of a mission to radically change the industry. We design and produce products at the right price, which meet the needs of every sleeper. All Hypnia mattresses are designed to last, guaranteed for 15 years and always with a trial period of 200 nights to satisfy even the most difficult sleepers. We deliver your mattress free of charge to the room of your choice, within a few days with the possibility of taking back your old bedding. Returns are free. We believe that everyone has the right to a good night's sleep, which is why we work with our associations and recyclers to ensure that every mattress returned to us is given to people in need.
