with swivel feature, is designed with resistance that prevents free spinning rotation which can cause spinal injury.
$150USD optional back-support with your choice of back bar


NOTE:The seat is raised with spacers as shown. Three reasons are that chair parts compatibility of the plate into which the back support slides (under the seat) conflicted with the swivel plate, and also, the knob for securing and adjusting the back support conflicted with the swivel plate. Both these reasons prevented the stool from swivelling properly.

Third reason is the swivel plate was extremely difficult to attach to the frame of the stool given the seat mounting holes already in place and close to the bend at the top of frame.

Any of the ‘concert’ basso 15″ round, oval, cutaway and double cutaway seats may be used on the ‘gig’ stools.

The SF double cutaway seat and the 13″ round seat will not fit on the multi-adjustable ‘concert’ basso due to the size of the seat mechanism on the ‘concert’ basso.
