I was very hesitant on purchasing a bed this way but i am truly pleased! I bought this for my 11 year old son. It came quickly and upon receipt it was set up within seconds.  The bed was fully expanded in less than a minute and the odor was minimal.  I aired out the room for about an hour and thats it!! I also purchased the mattress protector as well. It took him a few nights to get used to it but he absolutely loves it! Plan on purchasing a second!
