First off, when this gets delivered....this is very compact in the box making it feel way heavier than it is. They listed it as 75lbs, so be mindful if this needs to go upstairs. Very simple process to unbox and release the mattress from the plastic. Make sure to do this in an open area as this will pop open once you reach a certain point. Ive let the mattress relax for 48 hours and it seems to be of pretty good quality. Slightly firm, which is perfect for my almost 8 year old. Definitely recommend
