Vintage homes have cracks in their plastic - I understand that but when are they no longer just a cosmetic concern? We moved into a 1929 home and brought my gigantic, super heavy modern furniture. I see cracks and I am scared I am straining the basic structure of my lovely home. The king bed probably weighs 500 lbs, the super large all wood dressers about another 500 lbs. I purchased them for a lifetime 30 years ago - Drexel Heritage but I fear they are hurting my home.
