- Material and finish: Wood offers warmth and aesthetic harmony; verify finish does not damage crib surfaces.
- Installation ease: Look for tool-free assembly or simple instructions to minimize setup time.
- Portability and storage: If you anticipate moving the mobile arm between rooms, prefer lightweight or disassemblable designs.
