This chair is worth every penny. Got it on sale at my local store and the putting together took me maybe tops 10 minutes. It's comfortable the mesh prevents sweating the head rest is amazing; something you don't think you need until you have it. I work from home much better now no back nor neck pain. I highly recommend this chair to anyone.
I give the chair a 8.5 for comfort and 9 for sturdiness (out of 10). It is ergonomically a great chair to aid in good posture during long days sitting behind a desk. I personally like mesh chairs that breath well which helps reduce sweating when sitting for long periods of time.
After reading numerous reviews for this and the Hyken I ended going with this off the recommendation that this is identical in every facet other than in added roominess. I have to say this is an amazing chair that is not only comfortable but built well. Assembly was simple and the extra roominess that it supposedly has over the Hyken is very much welcomed. It isn't huge per se but more of what I would consider a "normal" chair to be in which case you could consider the Hyken as slightly narrower then. There is extra room between you and the armrests without having to worry about the sides hugging you and depth-wise it supports under your knees well with enough mesh seating so you're not resting on any hard plastic. If anyone is on the fence between the two as I was I hope this somewhat helps describe how the Dexley feels.
This chair is really comfortable. The mesh helps to keep you cool and it has lumbar support and a head rest for all over support. It is a great deal for the money.
