This is the PEARL ROADSTER Drum Throne D1500, which is also known for preventing lower back pain. I am selling it because I am replacing it. There are no noticeable scratches or rust, and it is in beautiful condition. Also, the seat has no sagging and feels almost new. The following is from the manufacturer's website: This round seat drum throne excels in stability and durability, and is designed with the player's body in mind. In addition to a comfortable seating experience that doesn't compromise footwork, it features a seat that distributes body pressure to reduce stress on the lower back, legs that are more robust and compactly designed than previous models, and a stopper that allows you to choose whether or not to rotate the seat. As a result of three years of research and development, the best possible technology is incorporated throughout. Please make your decision based on the photos, and no returns or refunds will be accepted.
