I have had this mattress for 3 years now. I bought it when I first moved to a new city and although I could tell it wasn’t actually firm I didn’t have much choice but to keep it because it was either sleep on this or sleep on the floor as I had no furniture. I struggle with low back pain and while I never really could blame the mattress I recently slept in a hotel for 4 nights and when I returned home last night and slept in my own bed I woke up with the same back pain I usually have but realized it had been completely absent on my trip. I now can point to the mattress as a contributing factor and I am so disappointed. I did a ton of research beforehand and tried to pick a firm mattress but this is just too pillowy.
