The Cinevate CIDOAS000003 Ballare height adjustable seat is a modular system that also incorporates a low angle/low shot mount for our 100mm bowl. In other words, remove the seat post portion of the system, and our 100mm bowl can be mounted from ground level, to about 1 metre elevation. The seat can be attached and removed from the center mast system using quick release clamps in about 30 seconds. The Ballare dolly will happily support up to 3 seats at the same time. The seat is designed to work with our telescopic support mast as it is stabilized this way!
