Stand chair up on an even surface and check that it is balanced. If there is a slight wobble, apply downward pressure in the corner where a leg is uneven. Keeping pressure in that corner, tighten all bolts. If balanced, apply downward pressure evenly in the center and tighten all bolts. Do not over-tighten beyond hole depth. Helpful Tip:-Instead of applying downward pressure while reaching under to tighten bolts,have someone sit in the chair while you tighten the bolts.
