3. Setup (Assembly Instructions)
This shelving unit features a boltless design for easy assembly. A rubber mallet (not included) is recommended to secure connections.
- Prepare the Area: Clear a spacious, flat, and stable area for assembly. Unpack all components and verify against the parts list (if provided with the physical product).
- Assemble the Base Frame: Connect two short upright posts to two long crossbeams using the keyhole slots. Ensure the wider edges of the crossbeams face upwards to support the MDF boards. Gently tap with a rubber mallet to secure the connections.
- Attach Additional Upright Posts: Connect the remaining upright posts to the base frame, forming the full height of the unit. Ensure all connections are firm.
- Install Shelf Crossbeams: For each shelf level, attach two long and two short crossbeams to the upright posts at your desired height. The keyhole slots allow for flexible positioning. Ensure all connections are fully seated and secure.
- Insert MDF Boards: Place the MDF shelf boards onto the assembled crossbeams for each level. Ensure they sit flush within the frame.
- Attach Plastic Feet: Place the plastic protective feet onto the bottom of each upright post.
- Final Check: Once assembled, gently shake the unit to ensure stability. If any part feels loose, re-tap the connections with a rubber mallet.

5. Maintenance
- Cleaning: Wipe the metal frame with a damp cloth and mild detergent. Dry thoroughly. For the MDF boards, use a dry or slightly damp cloth; avoid excessive moisture to prevent swelling.
- Inspection: Periodically check all connections and components for any signs of wear, damage, or loosening. Tighten any loose connections with a rubber mallet if necessary.
- Environment: Store the shelving unit in a dry environment to prevent rust on the metal frame and moisture damage to the MDF boards.
6. Troubleshooting
- Unit is unstable/wobbly:
- Ensure all crossbeams are fully seated into the keyhole slots. Use a rubber mallet to tap them firmly into place.
- Verify the unit is on a flat and level surface.
- Ensure weight is distributed evenly across the shelves.
- Difficulty assembling parts:
- Some components may require a firm tap with a rubber mallet to fit securely. Avoid using excessive force that could bend parts.
- Ensure components are oriented correctly before attempting to connect them.
- MDF boards have an odor:
- New MDF boards may emit a slight odor. This typically dissipates over time in a well-ventilated area.
