Very disappointed.
We have received one mattress after a 3 months of waiting and it was faulty. Hypnia sent another one straight away but is was faulty again and it is very soft and it is very different from the first one. We are waking up with terrible back pain. And the cover is different. I have a Hypnia mattress bought a year ago and it is with original Hypnia cover. These two faulty ones are not Hypnia at all or the quality is lower than before.
Not happy at all. Do not recommend
