Actually there is one DIY problem. You will need a 12” square surface about 20” high to place the seat section upside down to fasten the arms and then seating hardware. The instructions show these steps with the seat section “ in mid air”. Nonetheless each assembly stage has necessary hardware bagged no counting out different screw/bolt sizes and goes together beautifully. Oh yes the chair is comfortable also. I’ve had 3 back surgeries. I can sit in this chairs for 2 hours: other chairs only 45 minutes.
