The bed opens to its full size quite quickly and didn't seem to have much of an offgas smell at all, though we waited a day to sleep on it. The bed is a firm memory foam with a little give. Not too firm that you can't lay on your side, and feels good on your back. Gives enough support while still being comfortable. The bed doesn't really disturb another if someone moves, either. Gives a pretty good night of sleep, I would say. For the price, I would recommend this, for sure.
