5. Setup and Installation
The Sunifier L-Shape Furniture Risers are designed for easy installation. Follow these steps to safely elevate your furniture:
- Prepare the Furniture: Carefully lift one corner or side of the furniture you wish to elevate. It is recommended to have assistance to ensure stability and prevent injury.
- Position the Riser: Slide a Sunifier L-Shape riser under each leg of the furniture. The L-shape design allows for effortless placement and helps secure the furniture leg. Ensure the furniture leg is centered and fully seated within the riser's top contact area (4.1 x 4.1 inches).
- Check Stability: Gently lower the furniture onto the risers. Verify that each leg is firmly seated and the furniture is stable before applying full weight or using it. The triangular cone barbed surface and TPU rubber bottom are designed to prevent sliding and protect your floors.
- Repeat for all Legs: Repeat the process for all remaining furniture legs, ensuring even elevation and stability across the entire piece of furniture.

6. Operating Instructions
Once installed, your Sunifier L-Shape Furniture Risers provide a stable and elevated base for your furniture. These risers are suitable for a wide range of furniture types:
- Beds: Elevate your bed to create significant under-bed storage space, ideal for bins, boxes, or seasonal items. This also allows for easier access for robot vacuums.
- Sofas & Couches: Raise your seating to a more comfortable height, which can be beneficial for individuals with back pain or those who prefer higher seating.
- Desks & Tables: Adjust the height of your workspace or dining area for improved ergonomics or to accommodate taller users.
- Cabinets & Appliances: Use under cabinets, washing machines, or refrigerators to facilitate cleaning underneath and prevent moisture buildup.
The expanded and enlarged top surface (4.1x4.1 inches) ensures robust stability for furniture legs smaller than this dimension. The reinforced ribs within the risers contribute to their high load capacity.
