Parents and teachers, if you've got energetic kids who just can't sit still, this wobble chair might be your new best friend! Designed for children 6-12 years old, it actually helps high-energy kids focus better by letting them move while seated. The 18.1-inch height is perfect for most desks and tables, and it holds up to 154 pounds - way more than most kids weigh! The 1.3-inch thick molded foam seat keeps them comfortable all day, while the arc-shaped base with rubber bottom prevents slipping and sliding. Assembly is completely tool-free - just snap the pieces together and you're done. It's lightweight enough for kids to move around themselves, but sturdy enough to handle daily use. Perfect for homework time, classroom use, or any situation where kids need to sit but still have that urge to move. The ink black and dove gray colors look great in any room. Seriously, this isn't just a chair - it's a game-changer for helping fidgety kids concentrate better while strengthening their core muscles naturally. No more 'sit still' battles!
