nice chair , very comfortable , size is great easy to use locks are very good on this chair compared to some of the small little rings on other ones that i looked at , like the square tube design over the small round tube style , pad on the chair is soft , used it out in the sun without the pad works a lot better for the air flow to keep you cool , side tray could be a little more stable any heavy bottle tends to make it want to come off of the chair
