Comfortable mesh seat that in hot weather is preferable to foam. The back provides good support. It's easy to put together if you can use an allen key.
Excellent back support breathable mesh lining lifts high great neck support reclines nicely back support is adjustable... very ergonomic! Easy to put together too!! And great customer service by Staples store associate.
I've used the chair for a week with up to 10-12 hours of usage. The chair has a really good feature set for what you pay for especially on discount. However I was left pretty disappointed with the build quality. The mesh seating had stretched within the first week and when I properly adjusted my position my tail bone was resting on the plastic seat frame. The mesh also isn't very comfortable so I'd suggest wearing jeans or something thick when sitting. The chair also started making creaking noises when I reclined back and forth. I decided to return it after that. It isn't a bad chair but be aware that quality control isn't its strong suit and be prepared to do some returns and exchangesm
The build quality is good for the price. I'm sure this would be more comfortable for someone who is taller but for me (5'8" 165 lbs.) it was just too big to be comfortable. I ended up getting the Hyken instead and it's a much better fit. The tilt-lock on the Hyken is also a nice feature which the Dexley lacks.
You are unable to sit upright with your back touching the chair. It leans too far back in the upright locked position. Other than that it's a good chair. I was able to fix it by making an angled wedge to mount the chair back on but before that I was going to return it.
I sit in this chair for about nine hours per day. I find it to be comfortable and the mesh keeps me cool. I like that the headrest is adjustable and can be moved up and down for comfort.
