Many wrought iron quilt racks weigh around 12-15 pounds, although some may be heavier if they are larger or made from thicker iron. People often concentrate on the size of the quilt rack and the style before thinking about how much it weighs. This may or may not be an issue depending on you as an individual.
All suppliers should list the weight of their furniture products on their website and also on the label of the product, so finding out the exact weight of your preferred item shouldn't be a problem. You should make sure that you will be able to carry the quilt rack to your home and up any stairs.
