The chair was easy to assemble until we got to the headrest. The assembly time was nearly an hour and more than 45 minutes of that time was spent struggling to assemble the headrest.
Good chair just didn't like that the edge of the seat is raised hard plastic that'll dig into you if you try to sit cross-legged. Best thing is the 7 year warranty. I bought mine in 2020. Just called to get the mesh seat cushion replaced as it's beginning to sag a bit. Called a while ago to replace cylinder that sank into base and cracked it. No hassles at all. Nice to see a company stand behind their products.
I purchased this chair in Sept 2022 and have been using it as my work chair 8 hours a day 5 days a week. In December of 2022 I noticed the mesh was starting to stretch even though I'm under the weight limit (195 lbs). I ignored it because I expected it stretch... some. It's now March of 2023 and the mesh of the seat started to rip away from the frame. Totally unusable now and very disappointed.
I had the previous model I purchased 4 years ago. Recently I noticed the front seat deformed and I found out the front pad has dislocated and the pad broken. This one has stronger to support the front pad and it's unlikely to dislocate. I recommend this over the old model which is also mesh. Assembly is rather easy but I recommend to have color mark so correct screws can be used.
