Troubleshooting
- Difficulty during assembly: Ensure all parts are correctly identified and oriented according to the assembly instructions. If parts appear mislabeled or ill-fitting, double-check the manual and contact customer support for assistance.
- Bed feels unstable or wobbly: Verify that all bolts and screws are fully tightened. Ensure the bed is placed on a flat, level surface. If included, confirm anti-toppling devices are properly installed.
