Very comfortable. I'm 5/5. With the addition of a footstool I found I could adjust it to the perfect height very easily just by pulling the handle. Great support for my lower back. I did add a memory foam seat cushion it's perfect.
Simple enough to assemble everything included to do so and very comfortable. Casters provided are for carpet so if you’re going to use it on a hard surface you’ll need to purchase those separately.
The chair is comfortable for sitting a long time at your desk. The easily adjustable lumbar support is appreciated. The chair is also very light to move around in front of the desk to reach places to get needed supplies. The wheels easily roll over the edges of the floor protector that is also appreciated. The chair adjustment for leaning back to relax is also easy to adjust. The mesh surface prevents a sweaty seat and back. Assembly is very simple by using only an included allen wrench. The directions and separate packaging for all the well labeled parts are exceptional. These are the best organized directions I have ever used. There is one step where having a second person to help hold one of the parts being assembled would be very helpful.
After a week the Seat stretched so much & sags down so far that it's not comfortable to sit in. Leaning back will sometimes cause a loud pop like the plastic is being popped out of place. Avoid it it won't last long.
