Abstract

A chair having a seat plate supported by legs, the seat plate having a top side with two concaves therein below where a seated person's hip bones project and optionally an additional concave rearward of the two concaves and below where the seated person's coccyx projects. The positions of the concaves are selected to be where a performer on a drum is likely to be seated when playing a drum while seated. The two concaves may be circular or may be elongated in the forward-rearward direction. The seat plate may be circular or it may be a bicycle seat shaped with downward and outward sloping concaves for the femoral thigh regions at the sides and toward the front.

3. The chair of claim 1, wherein the seat plate has right and left sides toward the front of the seat plate which are concavely curved for holding the femoral thigh regions of the legs of the performer sitting on the seat plate with the hip bones generally above the first set of concave portions provided therefor.

4. The chair of claim 3, wherein the seat plate has a bicycle seat shape and narrows toward the front at the right and left sides.
