so after this was delivered i had it in the box for about a week, im not sure if that contributed but its taken over 4 days for the mattress to expand, i was supposed to move a week earlier and the place i moved into wasnt ready so i didnt really have a choice but otherwise it seems nice, its very cool to the touch and i cant wait to sleep on it, i think either tonight or tomorrow ill give it a shot, i dont want to sleep on it until its fully expanded.
