If you have wide shoulders or are taller than 6 feet you may have trouble really enjoying this chair. It raises up decently high but the head rest only reaches the base of my neck and presses against the back of my shoulders. The arm rests have decent height adjustment but screwing them into the chair base feels like you may warp or strip something because the fasteners do not screw in flat and flush against the mounting pieces. The base is plastic but seems sturdy for a heavy person as well it is rated for 275lbs after all. No signs or sounds of flex or breaking. The Mesh seat and back are comfortable and provide ample air flow as well if you're concerned about staying cool in warm spaces. The lumbar support piece while effective has minimal height adjustment and it's not the most accessible to reach and move especially when you're already seated. The lean works great and locks into place well. Combined with the lumbar support it really makes you sit up straight.
Delivery was quick and professional. Chair was packed really well and secure. Putting the chair together was a little difficult and I am very handy. You could stroke out trying to put the wheels on. Also the only bad thing I can say the wheels are garbage; I am already looking for replacements. I have vinyl laminate floors and this chair goes where it wants not where you want. Other than that it is very comfortable and seems very sturdy. Four stars is strictly because of the wheels. Over all I like the chair very much.
This is the second Mesh Chair I'm buying. The chair is great but the assembly needs to be improved. All bolts need thicker cap ( it breaks) and deeper key slots.
