Mattress is fine, but it’s let down by customer service, availability and delivery. After ordering the mattress I was told it was a 4 week lead time (which is in the website if you look hard enough). I waited 4 weeks with no communication, and chased hypnia and was told it would be another 4 weeks. I told hypnia I would be on holiday 4 weeks later and was assured I could specify a delivery date. Anyway, while on holiday I got an email saying the mattress would be delivered, I tried to contact hypnia and the delivery company to rearrange the delivery company and got silence (again). Mattress was then dumped on my doorstep while I was on holiday, which was a real problem. If you don’t need a mattress quickly, and are in all day everyday, hypnia will work for you. Otherwise avoid.
