Tama HT741B Ergo-Rider Quartet Drum Throne offers a versatile and comfortable design thanks to its ergonomic seat shape. A hybrid of a round seat and a saddle seat it has a front cutaway for unimpeded thigh movement and indentations with extra padding to encourage correct posture. With a quad-leg base and oversized rubber feet for maximum support and stability the Tama HT741B Ergo-Rider Throne features an easily adjustable height range with high quality Sit Tight seat clamp and Rocklok mechanisms. Enhanced Durability and Stability The HT741B features Tamas original “Sit Tight” seat clamp which securely grips the upper rod of the throne to keep it from wobbling. At the bottom of the threaded rod is the “Rocklok” which features a specially-designed nylon bushing to prevent side-to-side motion within the base. This provides exceptional durability and stability while playing giving you more time to focus on drumming and less time being irritated by a wobbling stool. Precise Adjustability 1st Chair thrones are fast to adjust but still offer exact height adjustment. Loosening the bolt lets you quickly raise the seat to the approximate height you want then the screw thread lets you make minor adjustments until youre entirely happy. The Trio leg base is 32mm wider than on previous models for greater stability and features the Foot Life plastic leg attachment which reduces wear and tear on the rubber feet whilst extending their life. The feet themselves are oversized (1.5 times larger than on previous models) offering optimal strength and stability.
