Luxury restaurant furniture should be regularly cleaned and maintained to ensure that it looks its best and lasts as long as possible. This can include dusting, polishing, and vacuuming the furniture on a regular basis. Any spills or stains should be cleaned up immediately to prevent damage. Additionally, it is important to protect the furniture from excessive sunlight and heat, as this can cause fading and warping. It is also a good idea to use protective covers or place mats on the furniture when it is not in use to help protect it from wear and tear. In the event of any damage, it is best to have a professional repair the furniture to maintain its appearance and value.

1. Regularly clean and dust the furniture to remove any dirt or grime that may have accumulated.
2. Use appropriate cleaning products and techniques for the specific type of material the furniture is made from (e.g. leather, wood, metal, etc.).
3. Protect the furniture from potential damage by placing coasters or placemats under drinks and using tablecloths or placemats to protect the surface.
4. Use furniture polish or wax on wood furniture to protect the finish and keep it looking shiny.
5. Address any issues or damage as soon as they occur to prevent them from becoming bigger problems.
6. Regularly condition the leather furniture to keep it moisturized and prevent cracking.
7. Avoid placing furniture in direct sunlight or near heat sources to prevent fading or warping.
8. Move furniture gently and with care to prevent scratches or scuffs.
9. Keep furniture away from high moisture areas to prevent mold or mildew.
Have regular maintenance check for the furniture, especially for the moving parts, to ensure that it's in good working condition.
