These. Chairs. Are. Awesome! I think the coolest feature of these chairs is the fact that they are dual lock. There is a small locking mechanism that locks the chair into place when they are folded up and when they are folded out. Its a quick release button you press when you need to unlock them which is very easy to use.
We've had them for about 3 weeks now and my wife and I both love them . These are the perfect chairs for watching sporting events or car camping. They are very comfortable and easy to relax in. There is a shoulder strap built into the chair itself (not just the bag) which makes it easy to pick up and move to another spot without having to store it back in the bag.
They are slightly heavy but I can comfortably carry two on my shoulder for short distances (i.e. from the car to the soccer field). Carrying them for longer distances would definitely be tiring. They do sit higher than most camping/folding chairs so if you're a shorter person you might find them to be slightly uncomfortable. Being 6' 2" these chairs are the perfect height for me. My wife who's 5' 4" however, barely touches the ground with her feet when she sits in them.
Summary: - Dual lock!!! - Two cup holders, one on each arm - A small storage pouch on the side of the chair - Very comfortable - Very sturdily built - Carrying strap built into the chair - Slightly taller than most folding/camping chairs - No sag seating
