I really liked my Beautyrest Black® Hybrid Mattress in terms of comfort, though I should have gotten something firmer in terms of support. The medium was just a bit to soft for my taste but it was a very high quality mattress and I was very pleased with it. It was probably one of the best nights sleep I've had in years honestly. The bed conforms to your body and it molds to you to give you the comfort of being cradled though not as deeply. The mattress is thick and fits perfectly on a bed frame of your choice.
