1. Product Overview
This manual provides instructions for the Leggett & Platt Adjustable Bed Leg Kit, 4" Height, designed to modify the height of compatible adjustable beds. This kit includes four black steel riser legs, each 4 inches in height, featuring an M8 threaded bolt for secure attachment.
The primary purpose of these legs is to allow users to customize the height of their Leggett & Platt adjustable bed, either raising or lowering it from its original configuration. The robust steel construction ensures supportive strength, finished in a sleek black.

2. Setup and Installation
These 4-inch black riser legs are designed to screw directly into the bottom of most Leggett & Platt Adjustable Beds that utilize an M8 threaded bolt connection. Installation is straightforward and typically involves simply screwing the new legs into the existing threaded receivers on your bed frame.
2.1 Compatibility
It is crucial to verify compatibility before installation. These legs are specifically designed for Leggett & Platt adjustable bed frames with M8 threading. They are not compatible with:
- Mattress Firm 50 Adjustable beds from Leggett & Platt.
- Reverie Model Adjustable Beds.
- Sealy or Serta brand adjustable bed frames.

2.2 Attaching Casters (Optional)
Each riser leg includes a provision for attaching a caster to its bottom. For proper fit, casters should have a 7/16" diameter x 1 1/2" H stem. This allows for mobility of the bed if desired.

3. Operation
Once installed, the legs function by providing a stable base for your adjustable bed at a fixed height of 4 inches. This allows for a lower bed profile compared to taller original legs, or a higher profile if replacing shorter legs. The legs are designed to support the weight of the bed and its occupants, ensuring stability during normal use of the adjustable bed's functions.
4. Maintenance
To ensure the longevity and continued stability of your bed legs, follow these maintenance guidelines:
- Regular Inspection: Periodically check all legs to ensure they remain tightly screwed into the bed frame. Loose legs can compromise stability.
- Cleaning: The manufacturer recommends "Hand Wash Only" for product care. For these steel legs, this typically means wiping them down with a damp cloth and mild soap if necessary. Avoid harsh abrasive cleaners that could damage the finish. Ensure they are thoroughly dried after cleaning to prevent rust.
- Weight Distribution: Ensure the bed's weight is evenly distributed and does not exceed the legs' weight-bearing capacity. Avoid placing excessive, concentrated weight on individual legs.
5. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Legs do not fit the bed frame. | Incompatibility with bed frame threading or brand. | Verify your bed frame is a Leggett & Platt adjustable bed with M8 threading. These legs are not compatible with Mattress Firm 50 Adjustable, Reverie, Sealy, or Serta brand frames. |
| Bed feels wobbly or unstable after installation. | Legs are not tightened sufficiently, or the bed frame requires more support points. | Ensure all legs are securely tightened. For split adjustable frames, especially those splitting horizontally, consider adding additional legs (e.g., purchasing a second set) to provide more support points and prevent bowing or instability. |
| Legs appear thinner than original legs. | Design difference from original equipment. | While these legs may have a smaller diameter than some original legs, they are designed to be sturdy. Ensure proper installation and consider adding more legs for very heavy loads or split frames if stability is a concern. |
