Wow! This chair is firm, supportive and stable. I agree with the other reviewers that this is the folding chair to buy. It's expensive but you truly get what you pay for.
It's not as heavy as it looks but it certainly weighs a bit more than the spindly umbrella-like folding chairs that cost less and close in on you when you sit down. When open and in place the seat doesn't sag much and your seating position is more upright, which is probably a good thing. The side table seems adequately sturdy and the side pockets are numerous and useful.
Opening and closing the chair takes some firm pressure, but that's just an indication of how firm and stable the chair is when open (when closing the chair, it helps if you lift one side of the chair slightly to allow the seat to collapse). It also has a fabric loop on the side of the seat back and a velcro attachment at the bottom of the rear leg that looks to be a provision for inserting a separate umbrella, though we haven't tried that.
This a functional chair with useful features that I believe will be a good long-term proposition for us and worth the cost.
