I actually bought this for my 11 year old daughter.  She recently moved up to a Queen size bed so she would have extra room.  She has had some back/spinal issues and has been through physical therapy.  We thought this could be of some help to her if her back begins to hurt again.   This is pretty solid and heavy duty. It wasn't light to carry.   As far as set up goes, it went quickly and easily for my 15 year old soon who set it up.   The movement is smooth and pretty quiet so if she decides to play around with the settings she won't be bothering anyone else.   It's at a great height also.  She can still put some items under the bed for storage.  There is even a piece atttached to the end to keep the mattress from sliding off.
