Set your chair on a level surface. Place one hand on the pole at the front of the armrest. Place the other hand on the opposite pole on the seat back, diagonal from the front pole.
Push out on both poles, forcing them away from each other. Repeat this for the remaining two poles, unfolding the chair completely.
Smooth out the seat bottom and the seat back, adjusting them as needed by pulling up on the fabric or pushing it down on the poles. Position the armrests by sliding the armrest fabric up or down on the rear pole until it is where you want it. Push the net on the cup holder down to open the cup holder.
Pull up on the seat bottom, pulling all four poles in toward the center to fold the seat up. Pull the armrests all the way up if necessary to make room for the fabric to fold. Pull the poles in together to fold the chair completely.
