The HT430BC Round Rider Trio Cloth Top from TAMA is a drum throne; traditionally, you would sit upon it while playing or practicing the drums. The throne, measuring 14' in diameter, is height adjustable from 19.0 to 25.8', providing a T-bolt system to complement its threaded rod construction to allow for quick changes in height. To prevent side to side wiggling of the seat, a special Rocklok system has been employed, as has a patented plastic leg-attachment system called Foot Life, which protects against wear and tear. Additionally, this model features a cloth-top manufactured out of a fabric which wicks perspiration, thus making sure you do not slip while playing.
