■ Model Number: DS550U ■ Seat Size: Round Seat (294mm diameter) ■ Seat Height: 37-55cm ■ Leg Configuration: 3-leg (single-braced) ■ Height Adjustment: Clamp rod system (without holes / with memory clamp) I purchased this new to carry around for use in venues without a drum set, and I've used it for several years. Although I've used it for several years, I basically didn't use it at home or in venues with a drum set, so I only used it a few times a year. Also, when I bought it, there were 3-4 white papers with English warnings? stapled to the back of the seat (you couldn't see them unless you flipped it over), but I didn't like the cluttered look, so I removed them immediately after purchase. Please be aware of this.
