Incredible! 
Was slightly skeptical but once it was blown up my toddler jumped right in it and even napped for 2 hours with no issue! 
The quality is so good, the size is perfect - it's the size of a crib with blow-up sides if that helps give you an idea of how big it is. Doesn't have a plastic smell which is nice since most air mattresses do!! 
I absolutely recommend this air mattress for anyone who is looking to take their little camping or anywhere. It packs down quite easily and is relatively small.
