We have slept well on the mattress since day one. And my hips stopped hurting! :) Setup was interesting, but pretty easy. It would be a challenge for an elderly person alonebut my husband is pretty strong. :)
Not being able to try the mattress out before I bought it; I was worried about it being too soft and saggy. When it arrived, I placed it in the bed frame and had a lie-down. It is soft, but firm. It's super-comfy. I'm glad I bought this specific mattress. I would definitely recommend to anyone looking for a good mattress. Thanks for making it!
