Keep your students attention by keeping them comfortable and ready to learn with this flex comfort stack classroom chair. Its heavy-duty construction strikes a balance of comfort and stability that makes it perfect for classrooms, home schooling spaces, and libraries. Designed for students ages 12 and up, this chair boasts an ergonomic flex back that promotes good posture as well as versatility that allows the user to find just the right position to keep from getting antsy and to stay comfortable, ideal for long lectures or extended study sessions. The vented back and seat allow for proper airflow and added comfort. The powder-coated steel frame is built for long-lasting durability and is engineered to hold up to 500 lbs. static weight. Fixed floor glides on the bottom of each leg make for easy movement around your space and are designed to protect hard flooring surfaces from scratches and other damage, meaning students can push their chairs back to get up without worry of damaging the floor. When not in use, cleanup and storage are easy thanks to a stackable design that allows up to 18 of these chairs to stack on top of one another to save space and reduce clutter. No assembly is required, meaning you can set up your classroom right away. Maintenance is easy by cleaning with a water-based cleaner. Pair this chair with our classroom student desk to complete the look and make the most of your learning space.
