A Hypnia mattress was recommended by our neighbors and wow i'm so glad we went for it. Delivery was faster than expected and it is the comfiest mattress I have ever slept on. It's a strange sensation as the medium firm is extremely firm to touch but as soon as you lie down on it you just sink into it and have the best sleep imaginable. Both my partner and I have said that our back pain has improved and felt like we have had a great night's sleep. Another great feature of the mattress is that I can't feel anything when my partner gets out of bed or rolls over etc so I'm not being woken up at all. Overall I'm super happy I went with Hypnia and would highly recommend!
