Brilliant mattress, comfiest I've ever slept on. The mattress is indeed firm but you never wake up achey. The only negative is that it does not have handles on the side because this is a heavy old mattress to lift when you are trying to put on a fitted sheet or turn it around. I bought my first hypnia mattress 6 years ago when the firm was in its infancy, and it's still as comfy as the first time. Since then I have bought 2 single ones for my child's room, and a double for my spare bedroom. My parents have bought two since sleeping on our spare and friends have bought them too. This is not a fake review - seriously these mattresses are awesome.
