Student Project: Ergonomic Chair for Acoustic Guitar Players

Here's my most recently completed school project:

The Guitarist's Pick...because the ergonomic seat is in the shape of a pick AND, hopefully it will be the chair that guitarists pick haha

Concept: Although this chair cannot heal callused fingertips, it can aid the guitar player comfortably endure hours of guitar playing and practice.  The chair features an extremely comfortable cushioned seat in a shape all guitar players can identify with - the guitar pick.  This shape also allows for leg comfort since there is no seat edge to press against popliteals or cut-off circulation.  The chair also features an adjustable foot prop so that both feet can be flat against the floor for maximum comfort.  The foot prop can swing to both sides to accommodate left-handed and right-handed players, and it also moves up and down.  The low cushioned back provides support for the lumbar region while also allowing the user to lean forward while playing.  Finally, the chair is constructed of lightweight materials so that the chair can be easily moved from practice room, to jam session, to stage.
