These stools are built with a sturdy painted steel frame and high-quality PP seats, offering durability and rust resistance for long-term use. Each stool includes an X-brace under the seat to enhance stability, ensuring a strong structure with a weight capacity of up to 220 lbs. The set of 6 stools is fully stackable, allowing for compact storage when not in use, making them ideal for tight spaces. Weighing only 16.5 lbs in total, they are lightweight and easy to move around. The 6 backless stools provide versatile functionality, serving as extra seating, plant stands, or side tables, and are suitable for homes, classrooms, dorms, offices, parties, and more. Each stool features a hollow-out seat with 8 ventilation holes, offering comfort even on warm, humid days. Non-marking foot caps protect the floor from scratches. No installation is required, and the 17.5" seat height works with most standard tables. The painted legs and PP seats are waterproof and easy to clean with a damp cloth.
