This is the seat of a black, suede-like drum stool with an ergonomic design. Thank you for viewing. I bought this because I wanted to try the fan-shaped saddle, but I couldn't get used to it, so I'm putting it up for sale. - Brand: TAMA - Model Name: HTS5BCNST [1st Chair Glide Rider Seat] - Color: Black - Shape: Ergonomic design - Material: Suede-like fabric The following is the manufacturer's description: The 1st Chair Glide Rider drum throne was created with the goal of "supporting the body's center of gravity stably and reducing the accumulation of fatigue when sitting for long periods of time." It features a hard urethane foam molded inside, and the top surface of the seat uses a cross material that prevents slipping during play, achieving an ideal balance of softness and hardness that was not found in previous TAMA models. This is a saddle-shaped drum throne seat. The nylon bushings equipped inside the seat holder fix the screw rod with a surface. It achieves high stability, resistant to lateral movement during play. The base can be attached to a 22.2mm diameter pipe/rod.
