Operating Instructions
The SpaceAid Rotating Bookshelf is designed for easy access and efficient storage.
- Loading Books: Place books between the retainer bars on each shelf. Ensure books are not excessively heavy or protruding to maintain balance and rotation.
- Rotation: Gently push any shelf to rotate the entire unit 360 degrees. The smooth rotation mechanism allows for easy access to all stored items.
- Weight Distribution: For optimal stability and smooth rotation, distribute the weight of your items as evenly as possible across all tiers. Avoid concentrating heavy items on one side or one shelf.
