Comfortable. The mesh seat gets a little soft and a thin pillow or towel is a good fill-in. The head rest is a super plus. The seat should have an adjustment to be able to move it forward or backward. The tilt adjustment knob is a plus.
I recently purchased two of these chairs for my use both at work and my home office. Overall the assembly is pretty straightforward it is a nice looking chair and for the most part comfortable. I am fairly tall and the only "slight" draw back I experienced is that the chair's seat does not move forward in order to provide better ergonomic support to my legs allowing me the ability to sit back further and fully utilize the lumbar support provided.
My whole family likes this chair. We are all different ages weights sizes shapes and heights and nobody has any complaints. We use this for homework paying bills working at a family desk with a family computer and work area. Used daily and appreciated daily.
Picked up the last stock item at Staple retail store. Being the last item box was not in great shape fortunately all the parts are in there. The chair is great I highly recommend this Hyken technical mesh chair. Cheers!
