I’ve wanted a mattress like this for awhile and I read online that this was less firm than an Endy and it had a better “weight transfer” rating (don’t feel your partner roll over as much). I sleep on my side and for the first few weeks I woke up stiff and not feeling great. We wanted it out andbaxtially started to talk about returning the bed. One week after we decided on a return we loved the bed (we hadn’t made a claim yet). We were no longer soar and the firmness is at a level we want. Super happy with it. Seems like good product:company
