I have some spinal issues, I had been laying on floor for 7 months. I has already ordered a "firm" mattress but it did not work. Had a hard time getting another one because sleeping on the floor was working. I did not want to rock the boat! So my step/daughter finally convinced me to get a Leesa mattress. I ordered the hybrid, sent my other one back and I'm permanently off the floor!! Every time I get into bed my mantra is "I love my new bed" I highly recommend Leesa. Not too firm, not too soft, not hot just PERFECT!
