￼It was relatively easy to put together following instructions, however after having this chair for a full month. It is very uncomfortable the seat has no cushion at all.  Sitting in this chair is as if you were sitting directly on the board that is underneath the chair.
I would not buy this chair again never. The lift on the chair is counter height  but bar underneath the seat that you can put your feet on to keep your legs from hanging when you lift the chair, which hurts your  
legs, is too far back from the seat so you have to really bend your legs back to eat your feet there.  You need to have a foot stool to prop your feet on to 
balance your body while sitting.
