This bed is definitely comfortable. Not sure if it’s vastly different from our previous mattress but I’m sure it was a lot less expensive. The reason for losing a star is that we let it expand for over a week and it only expands to just under 9”, not the 10” advertised. Not enough to go through the hassle of sending it back but a slight disappointment. Would order the 12” mattress if I had to do it over again and wanted to mention for people considering between those options.
