My wife had total ankle replacement and needs to spend weeks on her back or semi-reclined with her foot elevated.  I purchased a Lifetime table to put in the living room beside the sofa on which she could keep her medications, reading material, water, etc. along with personal items so that they will be within easy reach.  It works so well. It is adjustable in height and it is very sturdy and stable.  I would certainly buy it all over again.
