Chair is beautiful and comfortable but was difficult for me to assemble by myself. Thus the 4-star rating. The castors were almost impossible to get in. And attaching the back and seat together was difficult. I have experience assembling things but it would have helped to have written instructions not just pictures. All the pieces were there and packaged in a fashion to assist greatly. The only tool needed an Allen wrench was supplied too.
The chair is very very comfortable. I sit on it at least for 8 hours when a day when I work from home. Easy to assemble. Did it by myself. Nice cushions and easy on the back. Would definitely recommend to those looking for an inexpensive office chair.
