Why is the wood stain coming off my furniture and how can I prevent it from happening?

The wood stain on your furniture may be coming off due to factors like poor application, low-quality stain, or lack of proper sealing. To prevent this, ensure the wood is properly prepared before staining, use high-quality stain, apply multiple coats, and seal the wood with a clear finish to protect the stain. Regular maintenance and avoiding harsh cleaning agents can also help maintain the stain on your furniture.
