I am 5 ft 3in and both the head rest and lumbar support are perfectly positioned ….headrest is adjustable. I prefer the more “upright” aspect of this chair for computer work while I can very easily recline slightly when not in front of the computer. The arm rests are padded but nice and firm which adds to the ergonomic nature of using a keyboard affixed to the underside of my computer desk and are easily adjusting up and down….or adjusting arms wider or narrower - best to do that when putting the chair together. the seat and back are nice and firm yet flexible. This is not a good chair for very large people but I particularly appreciate the “slope” on the seat front so I’m not cutting off circulation as Inwouldnon larger chairs with deeper seats. I find it far more comfortable than my large leather executive chair! You will too.
And I really hope it holds up better than it’s predecessor- same brand one model earlier and the back is bent at about 15/20 degrees… fortunately I spent the $20 for insurance…
I have purchased this chair for use at my last for jobs due to my need for a truly supportive ergonomic chair. I used to have issues with standard office chairs but not since using this model. It is Easy to assemble relatively light and easily adjustable. It supports the seat lumbar and upper back areas and the adjustable tension on the back still allows for the firm support I need. The Mesh seat and back also help ensure even pressure and air circulation . The adjustable arms allow for setting a proper height for ergonomic use of a Keyboard. Same for the adjustable seat height. Only caveat just 2 years ago this chair went for only $130 and now its around $300 not discounted. Still I'd recommend this to people working at home or in the office that want to mitigate existing or prevent ergonomic-related back and arm problems.
