- Prepare Your Workspace: Clear a flat, clean area for assembly.
- Understand the Components: Familiarize yourself with the plastic panels and connectors. The connectors have multiple slots for inserting the metal rods of the panels.
- Assemble the First Cube:
- Take four 12"x12" panels and four connectors.
- Insert the metal rods of two panels into opposite slots of a connector. Ensure the panels are fully seated and the connector is firm.
- Continue adding panels and connectors to form a cube shape. Ensure all connections are tight.

- Build Additional Cubes: Connect additional panels and connectors to the first cube to expand the structure. You can create various configurations (e.g., 2x4, 4x2, or a custom shape) using the provided panels. The 12"x7.25" panels are typically used for the sides of narrower sections or for creating shelves within larger cubes if desired.
- Secure the Base: For the bottom layer, ensure the connectors are oriented to provide a stable base. Some connectors may serve as feet for the unit.

- Final Check: Once assembled, gently shake the unit to ensure all connections are secure and the structure is stable. Adjust any loose panels or connectors.
5. Usage and Capacity
The Mainstays 8-Shelf Closet System is designed for organizing various household items. Each individual cube has a maximum weight capacity of 6.6 lbs (3 kg). It is suitable for storing:
- Folded clothing (e.g., shirts, sweaters, jeans)
- Shoes
- Hats and accessories
- Books (within weight limits)
- Lightweight decorative items
Avoid storing heavy items such as large textbooks, tools, or heavy kitchenware, as this may cause the panels to warp or the structure to collapse.
6. Care and Maintenance
The plastic panels are designed to be dust-proof and water-resistant, making cleaning simple.
- Cleaning: Wipe down the panels and connectors with a damp cloth. For stubborn marks, a mild soap solution can be used, followed by wiping with a clean, dry cloth.
- Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the plastic material.
- Regular Check: Periodically check all connections to ensure they remain secure, especially if the unit is moved or heavily used.
7. Troubleshooting
- Unit is Unstable: If the unit feels wobbly, check all connectors to ensure they are fully seated and securely attached to the metal rods of the panels. Apply firm pressure to each connection point. Ensure the unit is on a level surface.
- Panels are Warping: This usually indicates that the weight capacity of a cube has been exceeded. Remove some items to reduce the load.
- Difficulty Connecting Panels: Ensure the metal rods are aligned correctly with the connector slots. Apply even pressure. If a connector is too tight, try rotating it slightly or using a different connector.
