Operating Instructions
The DUMOS L-Shaped Desk is designed for straightforward use once assembled.
- Utilizing the Reversible Design: The desk's L-shape can be oriented with the longer side to your left or right, depending on how you assembled the shelving unit. This allows for optimal placement in various room configurations.
- Adjusting Shelves: If you need to change the height of the shelves, carefully remove any items, detach the shelf boards, and re-secure them at the desired height using the provided hardware. Ensure all connections are tight before placing items back on the shelves.
- Using the Side Storage Bag: The fabric bag provides convenient access to frequently used items. Distribute weight evenly and avoid overloading to maintain stability.
- Adjusting Feet: The adjustable feet at the base of the desk allow for minor height adjustments to compensate for uneven floors, ensuring the desk remains stable and level. Rotate the feet clockwise or counter-clockwise to raise or lower each corner as needed.
