I've had this chair for a while now and I'm pretty happy with it's construction. The mess is plenty stiff and will support your weight and the mess has enough give that you sink into it comfortably assuming you're not a giant. The adjustable armrests are nice and while I haven't changed the backrest setting it's nice to know you can lean way back with little weight if you want to. Sturdy comfortable and well worth the price.
It's actually quite a comfortable chair for working long hours in because it is both supportive and breathable with just the right amount of give. Also good - super easy to assemble! It only took me a minute to realize that I had put the arm rests on backwards! Other than that it is a very comfortable chair which I can recommend for anyone who needs to sit at a desk for any length of time.
I love this chair. It is comfortable & adjustable. For the most part it is easy to put together. However my husband & I couldn't figure out how to get the wheels on. I decided to do without the wheels because I have a linoleum floor. I would definitely recommend this product.
