Everyone needs this.  It helps to protect your table from spills and scratches & can absorb condensation.  I always use one under any tablecloth — it gives some heft to the cloth & elevates the appearance of your table. You’ll still need trivets for hot items fresh out of the oven.  The best part — you just toss it into the washing machine & dryer.  I’ve used this for years & recently bought this new one for a second table. Protect your table.
