Designed and crafted in Belgium. Nata Umbrellas feature a magnetic system to open and close canopies with a click. Canopy fabrics are weatherproof, mold- and mildew-resistant, and resistant to stains and fading. Umbrella frames are lightweight yet sturdy, made from all-weather, rustproof aluminum. Umbrella bases feature stainless steel caster wheels that can be locked to prevent movement and unlocked to move the umbrella around your space. Nata Umbrellas are designed to resist winds up to 24 MPH and should be collapsed when not in use. Bases do not require pavers. A protective, custom-fit cover is included with each umbrella.
