I bought this chair to replace a chair that had served much longer than it should. The chair was in stock so there was no waiting for delivery. Assembly took about twenty minutes. I find the chair to be all that it is advertised to be. The only down side I have found is that my dog does not like the mesh seat. She would rather have a cloth cushion. When her computer skills improve I will consider getting her a different chair.
The angle of the seat is not adjustable independently. The front is either too high and cuts of the circulation in your legs it leans to far forward making you feel like you are about to roll out of the chair. No good in between. Head rest adjustment is not that flexible. Had to take it off because I could not get it to the right height for a comfortable fit.
This chair is the most comfortable chair not just when you first sit in it but all day long. With all the adjustments the whole chair really is contoured to the body and supports both the lower and upper back. The neck rest is great for long days at the desk. If there was one feature that would make it even more adaptable is to have arm rests that pivoted (rotate inward and outward) as well as adjustable height. Then this would have made the chair perfect.
We are happy campers in this office. We bought three Hyken Technical Mesh Task Chairs and LOVE them. Took two people and some time to assemble but it was well worth the work. I would highly recommend.
My son is 6'2" and he had read reviews before we made our purchase that said the chair headrest was in an awkward position for a tall person so we just didn't connect it to the chair. Otherwise it is very comfortable nice simple design easy to clean feels sturdy. Good value for the price.
