Using these chairs is a breeze. Just place them where you need seating in your classroom or your child's bedroom. Since they require no assembly, you can start using them right away. When it's time to store them, stack them up to 10 high to save space. As for maintenance, simply wipe them down with a damp cloth for regular cleaning. Avoid using harsh chemicals as they might damage the polypropylene shell. Also, keep in mind that the chairs are designed for students in Grades K - 2, so make sure to use them within the recommended static load capacity of 286 lbs to ensure their long - term durability.
