Shelving system for musical instrument storage

Adjustable musician's chair

A chair, specifically engineered and designed for musicians which in both adjustable and stackable. A highly developed human factored design which is mechanically correct has been developed. The basic framework for the seat pan and back support of the chair is specifically designed and contoured to enable a performing musicians to breathe properly while comfortably seated. Blow molded plastic is used for the seat pan having a desired amount of flexibility. The seat pan is covered by molded foam and a stretch fabric to enhance the function and comfort of the chair. This combination of materials prevents degradation of the posture configuration of the pan for the life of the chair. The backrest is similarly designed and provides upper back support rather than just a posture guide. The general plane of the chair is tiltable so that the chair can adjust to meet the needs of weight bearing instrumentalists, such as violinists, and can also be used to address the power breathing problems of wind and brass instrumentalists, such as trumpeters. The design of the tilting mechanism and the legs of the chair are such that the chairs can be stacked for storage.
