Project Background: A municipal-level comprehensive gymnasium, accommodating professional basketball games, mass fitness activities, and cultural performances.

Customized Configuration: 2271 fixed seats, 784 electrically retractable bleachers (mid-back blow-molded chairs); 10-tier structure, 480mm row spacing, 180mm step height; electrically operated one-button unfolding/retraction with anti-tipping and anti-pinch features; silent PU wheels to protect the wooden floor.

Results: When retracted, the thickness is ≤600mm, providing a complete basketball court; unfolding takes less than 10 minutes, suitable for frequent game switching; over 300 days of use per year, low maintenance costs.
