I think this chair (and likely all of similar design) would be difficult for anyone truly frail to recline.  This is my only "complaint".  Getting it back upright is relatively easy.  
It is currently in my bedroom though it will eventually end up on the patio.  Due to leg/ankle swelling my doctor wants my feet up 20-30 minutes several times a day.  I'm unwilling to spend several thousand on a recliner sight unseen.  This chair is proving to be a very satisfactory interim solution.
