Using these chairs is super easy. Just take them out of the box and place them wherever you need seating for kids in Grades K - 2, like in a classroom or playroom. Since they're stackable, you can stack up to 10 chairs together when not in use to save space. Make sure to place them on a flat surface to ensure stability and prevent tipping. When it comes to cleaning, a simple wipe - down with a mild soap and water solution will do the trick. Avoid using harsh chemicals as they might damage the polypropylene shell. Keep in mind that the static load capacity is 286 lbs, so don't overload the chairs. Also, since there are no metal parts, they're safe for small children, but always supervise kids when they're using the chairs to prevent any accidents.
