Yes, adding a glass top can protect your wood coffee table from scratches, spills, and general wear. Make sure the glass is cut to fit well, with smooth, rounded edges for safety. Tempered glass is the best choice because it’s durable and less likely to shatter. A glass top also makes the table easier to clean and can highlight the wood grain, adding a touch of elegance to your decor. Just be mindful of fingerprints and dust, as glass tends to show these more easily.
