The MI-932 high-density upholstered seat cushion achieves the perfect balance between firmness and softness.

Perfect for sitting, leaning, or keeping a space-saving low profile while you stand, our 360 swivel, spin, and tilting wobble stool seamlessly adapts to your workflow while reducing strain on your lower body and promoting good posture. And when you need to adjust in height, a simple press of an easy to reach handle ring underneath the seat activates the air-lift piston mechanism.
