It is a good mattress. Not very hard. We had ordered plank before and could not sleep on it as it was rock hard and we were getting worse back aches than on the soft mattress we got rid of. The support team was amazing helping us order the current mattress and returning the plank. The whole process took a while but we had the guest mattress interim. The only thing that I do not like about the hybrid is that it is a bit noisy, but I will take that vs the sleepless nights in plank.
