At Furniture Castle, your family’s safety is our top priority. Unsecured furniture can tip over and cause serious injuries, especially to young children. To help prevent accidents:

• anchor furniture securely to a wall or floor.
• heavier items in lower drawers or on bottom shelves.
• on furniture not specifically designed to hold them.
• only one drawer at a time to prevent tipping.
• climb, sit, or hang on drawers, doors, or shelves.
