I am tall (5’10”/178 cm) and needed a chair that can support my long legs. This chair so far has been helpful for my legs and back. I am also wide in size and it fits me perfectly. Headrest isn’t really great hence the 1 star deduction but you can remove the extra part. I just keep it on since I paid for this product.
I needed a chair with a head rest. My existing office chair had support for only my lower back. The replacement chair is comfortable and works great for me. Ensure you sit in the model you are considering to buy to ensure it fits your body.
It's only been 11 months and the mesh seating is already starting to tear. At first I needed a chair for the hot sticky days and the mesh assures that nothing will stick to any exposed skin and that my behind doesn't generate the usual heat from sitting on the average chair leaving it at a cooler temperature. But I'm a heavy guy at 270lbs so the "hammock" is already starting to sink to the bottom of the seat.
