This drafting height chair is better than I expected. The cushion is a large size and has a comfortable contoured seating surface. The foam is density, stiff and feels good sitting on it. I like the range of height adjustment, going from counter height to standup desk height. The plastic armrests while hard are still comfortable.It was easy to assemble. It takes as much time to remove the packing materials as it does to put together. All parts were included plus an Allen wrench and there is even an additional package of one each of every fastener just in case one is lost. This is extremely thoughtful in my opinion. The lumbar support it interesting. It is flexible plastic wings that sit behind the mesh back. When I lean into the lumbar it flexes and conforms perfectly to my back shape. It provides good support.A couple of minor issues: The back angle is fixed and not easily adjusted. I found it to lean farther back than I like. I added a stack of four washers under the front mounting screws to tilt it forward and now I like how it sits. The only other thing is there are some molding parting lines on the arms that bothered me. I was able to remove them quickly with a nail emery board.Overall, this is an excellent quality office chair for the price. It will work well at my sewing room cutting and drafting table.

Easy to put together. Solid construction. Height adjusts easily and adjustable foot rest. Also comfortable! Definitely would recommend.

I love the design of this chair, it's looks like a really high end chair and if feels like it too. The base is seriously heavy metal giving me confidence in the sturdiness of that base.I discovered a life hack when putting this together: put odd shapes together on a sofa so they don't slide all around. It took me about 30 minutes to assemble after I figured out how to.One feature I was shocked to find out is how high the seat can go; it's very, very, very high. It still goes down to normal heights but that extra height will let me use it at a counter top if I want to.Sitting in the chair is really comfortable and there's an adjustable lumbar support in the back just like my Herman Miller chairs. Oh, and the armrests can be easily lowered if you don't want to use them. Those armrests are hard plastic with no cushioning though so keep that in mind.One of my favorite features is the foot rest. I use a floor/foot cushion because I have short legs so that rest is a godsend.I absolutely love this chair from the comfortable mesh back, lumbar support, foot rest, wildly variable height, et. al. It's a great chair!

Relatively easy to put together, was able to do on my own. Chair is comfortable, seat is wide and is easy to adjust. It's a little hard to move around on carpet when seated, but not a big deal.

The adjustable levels are outstanding. Being 6'8, 230 the chair is sturdy and very comfortable, have used it daily since it arrived. Easy set up with good directions.
