4. Assembly Instructions
This bed frame features a tool-free mortise and tenon assembly method for most structural components. Follow these steps carefully.
- Prepare the Area: Clear a spacious, flat area for assembly. It is recommended to assemble the bed frame in the room where it will be used.
- Attach Headboard Legs: Secure the support legs to the upholstered wingback headboard. Ensure they are firmly attached.
- Connect Side Rails to Headboard: Align the mortise and tenon joints of the side rails with the headboard. Gently slide them into place until they are fully seated. No tools are required for this connection.
- Attach Footboard: Connect the footboard to the other end of the side rails using the same mortise and tenon method. Ensure all four corners are securely interlocked.
- Install Center Support Beam(s): Place the center support beam(s) into the designated slots or brackets on the side rails. Attach any accompanying support legs to the center beam(s) and adjust their height to ensure they firmly touch the floor.
- Lay Out Slats: Unroll or place the plywood slats across the bed frame. The slats are designed with a Velcro system to keep them in place and noise-free. Ensure they are evenly spaced and secured to the side rails.
- Final Check: Verify that all components are properly assembled and tightened. The frame should be stable and free of wobbles.

7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Bed frame is wobbly or unstable. | Loose connections; uneven floor. | Ensure all mortise and tenon joints are fully engaged. Check and tighten any bolted connections. Move the bed to a level surface or use shims if necessary. |
| Squeaking noises. | Loose connections; friction between parts; mattress movement. | Tighten all connections. Ensure slats are properly seated and the Velcro is holding them. The bed frame includes noise-reduction padding, but ensure it is correctly positioned. |
