I have mixed opinions about this chair. Most of the chair is well designed, made of quality materials, and is quite comfortable. My first concern is with the locking mechanism that holds the chair in the desired position. It is made of plastic instead of metal. I can't see it lasting more than a season or two before the plastic breaks. Secondly, while sitting on it, it is very diffucult to put in the reclining position. Seniors or people with back or knee problems will have much difficulty reclining this chair on their own.
