When selecting outdoor furniture for non-slip surfaces, durability and stability are key. Materials like powder-coated aluminum, teak, and synthetic wicker are excellent choices as they resist slipping and withstand weather conditions. Opt for furniture with textured finishes or rubberized feet to enhance grip. Chairs and tables with wide bases or low centers of gravity also reduce the risk of tipping. For added safety, consider modular or heavy-duty pieces designed for high-traffic areas. Combining functionality with aesthetics ensures a stylish yet secure outdoor space.
