Abstract: A guitar support device permits ergonomic use of a guitar by a seated user, without attachment of any damaging hardware to the instrument. The guitar rest receives the lower and upper bouts of a guitar body with a complementary shaped frame. Stabilizer mounts abutting the guitar face and at least one stop abutting the guitar's back secure the device. The ergonomic support securely cradles the guitar so that the user may move around to better play or to relieve pressure points. The weight of the guitar is distributed over the user's leg and supported by a toe that descends vertically between the user's legs and abuts the surface upon which the user sits. The device is hinged to allow it to fold and skeletally framed to reduce weight and create a carrying handle, both of which make it easily transportable and storable.
