I purchased this Zero Gravity Bed for my mother.  The legs are adjustable so no matter if your short or tall you can adjust them to your liking. My mom is 5'2 and she has a 12" mattress and has no problem getting on or off the bed.  There is a USB plug on the side of the bed, which makes it very convenient to charge your phone and it has a light under the bed which helps if she has to get up in the middle of the night.
