Our kids wrestle and we got these for them for Christmas so they don't have to sleep on the dirty, hard floor while waiting for their next match! As long as you have some room to move to inflate, it is great and my kids love them!
My wife ordered this and when it came, I grabbed my portable air compressor to fill it up for my daughter. I didn't realize that you have to swoop the thing around in the air for it to work. It's a challenge to fill it up inside a house so I think this is mostly for outdoor use and not for a 7 year old's bedroom.
Really like this! We just used it for like 30 min in the backyard to try and other than taking us a second to inflate it (didnt read directions but even after that it was a little tricky til we got the full hang of things) its awesome! Our five year old kept jumping on it (do not reccomend) and it withheld the jumps! Can be a little tricky getting off (each time I kinda just plopped off) but overall I really like this and look forward to using it more!
