INSTRUCTIONS:
⚠ Do NOT use electric tools to tighten screws. Hex Wrench ONLY!
When you assemble your Footrest, and tighten all 8 screws very firmly, the sides should be straight up and down. These are machine screws, and tightening them firmly will not strip the wood.

In an extreme case, the shelf may not rest firmly in the top couple slots, and can fall down on one side.
If that happens, here is a simple adjustment to bring the handles back in together permanently:
