I'm happy with my purchase. The backrest attaches to the throne securely, and offers a good range of adjustment both up and down, and forward and backwards. It helps with my posture, whilst at the drumkit. I have experienced some back problems recently and the back rest definitely seems to help. I already had a K&M throne so just needed the backrest. Even adding the price of the throne, it is still competitive with other brands. It doesn't fold down, so you need to carry the backrest and seat together, or dismantle and assemble these for every gig. Overall, I would recommend it.
