These mattresses are a bit disappointing.  They inflate and deflate incredibly fast and easy, which is awesome.  However, this is our second Intex air mattress and this one hasnt held up well at all.  Our kids like to sleep in our room on the weekends so we use it once a week.  They are 4 and 8 and are told to absolutely not jump on the mattress in any way, but this one already starts deflating slowly while they sleep. My son fell off the other night because it got really soft.  Also, the original one we had wasnt this tall and I liked it better.  The edges and corners of this bed are not nearly as strong or supportive as the shorter version, so if you get to close to the edge you do feel like you may roll right off.  There doesnt appear to be any hole or leak anywhere I can find.  Im wondering if the valve that inflatesdeflates the mattress has a slow leak.  Anyway, I dont think I can return or exchange at this point, so were stuck with it.
