Purchased my chair based on the comfort of the one my daughter purchased one month earlier. Her chair is the blue version - it is comfortable - right out of the box comfortable. My chair is grey and the seat is not nearly as comfortable or cushioned as her chair. Why? No quality control?
This is the second version of this chair that I've bought. The first one came mostly put together and was a decent chair for the cost. This new one however required more labor to put together (which can't be done by one person) and the parts and pre-drilled screw holes don't line up which means I have to choose which pieces get the screw tie down and which ones are left hanging (you can't just drill a new screw/hole into the materials of this chair). Very frustrated with the chair.
Well made for the price and comfortable. Arms are made of a sturdy material and easily move up out of the way when needed. Relatively easy to put together in an hour or less if you don't mind allen wrenches (which comes with the chair). I needed a chair where the arms could fold up out of the way to fit under my desk due to a tight work area. This one works great.
