We recently had a redwood deck with roof built in our back yard and bought a patio furniture set (10 piece) made with Steel Gray Aluminum Frame with Powder-Coated Finish on the legs and frame. The problem is when we set the patio furniture and people sat on it, we noticed marks and indentions from the legs of the furniture. What can we use to prevent our deck from the damage, especially from the weight when people sit? My husband wants to put tennis balls on each legs but I think that would look tacky and take away the beauty from our redwood deck and furniture…help please!!!!!
