Not a better mesh seat and back chair for the money can be found. Instructions were pictorial but good enough to assemble without error. I put a set of easy roll casters on instead of the wheels provided. This would be a worthy upgrade from the manufacturer.
Definitely worth the upgrade nice and cool when its hot and fairly easy to assemble. Had bad posture but this chair helps keep things aligned and the head rest keeps my head in a comfortable position while looking at my computer monitor. Good for WFH.
I purchased this chair June 2020 and today (July 2021) the fabric mesh on the seat has begun significantly tearing. I am 6' and180lb and have been using the chair with a sit/stand set-up so I am at most sitting 6 hours per day. The armrest plastic has also cracked to expose the foam but that I could live with. The chair was great for my needs when it was intact. Becoming unusable after a years use is somewhat unacceptable even at a low price.
