Hard. Soft layer on top is very thin. I’m female and a side sleeper and my hips hurt from sleeping on my side. My husband likes the mattress and he’s a different shape than I am.
I ordered the queen size with the platform. It was installed through the white glove service. Delivery men were clean, professional, and quick. I had a pleasant sleep every night since this bed arrived. The best parts of my day are raising the back and leg area into a reclining position and allow myself to meditate comfortably. Nowadays, if I have a choice between my sofa or Casper - I choose the Casper. During my Shavasana (a final yoga pose) - I have to choose between my plush yoga mat or the Casper...well, I'm on the Caspar. Namaste!
This is an outstanding mattress, we have been sleeping on it for about 30 days and both of us truly enjoy it. It the first mattress that both of us agree on. If your looking for a new mattress this is the one.
