Thank you for viewing. This is a drum stool with a large square seat and a stable 4-leg structure. Specifications: ■ Drum Throne ■ Seat: Large Square Seat (W480mm x D390mm) ■ Seat Mount: Large Die-cast Mount ■ Height Adjustment Range: Screw Rod System (460mm - 650mm) ■ Legs: 4 legs (double structure), wide stance ■ Large Seat Mount Made of aluminum die-cast. Features excellent stability and durability. ■ Screw Rod Adjustment System Rotate the seat to adjust to your preferred height and tighten the clamp. ■ Big Rubber Feet In addition to the wide stance legs, the big rubber feet provide maximum grip and firmly stabilize the stool's position. I purchased this year and used it indoors. There are no noticeable scratches or defects. It is no longer needed because I sold my drum set.
