Items arrived in 1 box. Assembling was easy with 2 main steps in less than 10 mins. 1. twist on each of the 4 chair legs 2. slip the back rest into the slot of the the chair and then the hair is ready to enjoy. For me, the chair was right in sz and I am 5'8", but i think it would be too small for anyone taller. The back rest reached my thoracic curve, as you can imagine it doesn't get too comfortable. The seat is firm, and its already softening up after a month of occasional usage. This chair is priced correctly for the sz and quality.
