The best way to protect your furniture is to have a nice piece of clear glass placed right over the table. Covering your table with glass will make it easier to clean, more hygienic, eliminating any chance of damaging a beautiful polished surface.
Floating glass is recommended to start at 6mm thick and toughened for your piece of mind. Glass thickness will vary depending on the application you are using it for. 5 – 6mm: Best used for small coffee or bed side tables also used to cover dining table with solid support all around. 8mm: Good for small coffee or bed side tables that may take a little weight. 10 – 12mm: Recommended for use dining or frameless tables.
