Benefits of a NPS 30" H Square Stool with Hardboard Seat

The NPS 6330 30" Square Stool is a practical and durable seating solution for classrooms, labs, and art studios. Its hardboard seat is securely attached to a sturdy steel frame, making it ideal for high-use educational spaces. The fixed height design provides a stable seating option for elevated surfaces such as lab tables and workbenches. Reinforced under-seat rivets and a square frame add to its structural integrity, while the foot rings promote comfort. Non-marring glides help protect your floors. Whether in science rooms or maker spaces, this stool supports daily use with long-lasting strength. Explore the key benefits below:

  • Heavy-Duty Construction

    Built with a 7/8" diameter 18-gauge steel frame and riveted seat attachments, this stool offers unmatched strength and reliability. It can support heavy daily use in educational or industrial environments without loosening or bending over time.

    Comfortable Footrest

    The welded foot ring provides added leg support and comfort for users sitting for extended periods. It also improves posture by giving students a place to rest their feet, especially at higher seating heights like lab counters or art tables.

    Floor Protection

    Equipped with non-marring glides, the stool protects floors from scratches and scuffs. These glides make it safe to use on tile, wood, or vinyl surfaces—ideal for classrooms and labs where furniture is frequently moved.

    Minimal Maintenance

    The hardboard seat and steel frame require very little upkeep. The smooth surfaces can be easily wiped clean, and the riveted construction ensures the seat remains securely in place even with regular use.
