These Nardi Riva Bistrot side chairs are easy to use. Just place them wherever you need a seat, like in a restaurant, on a patio, or by a pool. They're stackable, so when you're not using them, you can stack them up to save space. Remember, the weight capacity is 300 lbs, so don't overload them. The non - slip foot pads are replaceable. If they start to wear out, simply replace them to keep the chair stable. For maintenance, since they're made of commercial - grade materials that resist fading, peeling, and rusting, a simple wipe - down with a mild soap and water solution will keep them looking great. They're suitable for both indoor and outdoor use, but if you live in an area with extreme weather, it's a good idea to store them indoors during harsh seasons to extend their lifespan.
