To adjust the back of the chair, change the position of the beads and knots. The higher the knots, the higher the back will be. Keep the beads on top of the supporting knots. This will prevent the knot from becoming so tight that you cannot untie it. The set of knots closest to the chain-stitched edge should be about 3 to 4 inches higher than the second set of knots.
For even wear, periodically adjust the back up and down. If stretching in the seat of the chair occurs, simply switch the beads and knots from the back of the chair to the front. Do this one bead at a time until you are used to making the switch. After a few switches, wash your hammock.
