Question: Would an older person be able to get up off this comfortably?
Document: I purchased this mattress as a gift for my grandson to use when he stays overnight with a relative. It was was received 5/19/14 and first used in mid-June and as of today (7/11/14). It has only been used seven times by my 11 year old grandson. The mattress has now started to deflate while he is asleep.
But since it won't hold air -- it being easy to inflate or being comfortable doesn't matter since the mattress won't stay inflated so that cuts out the it being comfortable. Total waste of money for something that stops working after a few uses.
Answer: no
