Following three years of exhaustive research and development, Pearl’s professional Roadster thrones have been updated to give drummers the right support where it is needed most. The difference lies in each Multi-Core throne top. Using multiple layers of varied density foam that wrap around the surface of the cushion, Multi-Core’s ergonomic design and computer-tempered surface provides support to ease joint pressure during long sessions. Models include the D3500 Multi-Core saddle-style throne (available solo or with a fully adjustable backrest,) round cushion Multi-Core models with shaping peaks to ease pressure, and the revolutionary D1500TGL Trilateral Gas Lift throne, which delivers the feel of both round and saddle cushions depending on how they are mounted by the drummer.
