I had an air mattress back in my college days that was not very good.  It leaked and had to be constantly re-filled.  Needless to say I was not inspired to buy and air mattress when my Mom got sick and I needed something to sleep on while I stayed with her at her apartment.  with not a lot of options i tried this and it is not even comparable to the one from 20 years ago.  Taller, with fast inflation...and no leaks!
