A Unique Angle On Comfort.

Benefits of a Saddle Stool

  • Better posture as the vertebrae discs align naturally, resulting in immediate improved posture with less spinal muscle degeneration.
  • Tension relief in the shoulder and neck area due to the improved positioning of the thoracic and cervical spine.
  • Deeper breathing occurs due to the stretching of the torso allowing for better circulation, resulting in less fatigue.
  • Improved mobility and reach is easily achieved as the legs are free to “scoot” around the operatory, while remaining seated.

Why the Brewer 135DSS?

  • Circular movement and tilt

    • Unique 360° tilt makes movement easier and more natural.
    • Allows core muscles to become active in supporting the spine.
    • Strengthens spine stability muscles, pelvic and leg muscles.
    • Less pressure on the edges of the upper legs when moving side to side.


  • Split Seat design

    • Improves circulation as there is no edge to press against your upper legs. The veins and arteries that carry blood to and from legs are in the most open position for improved circulation.
    • Offerings superior cooling comfort, resulting in improved genital health in both men and women.
    • Balances the pelvis in an upright position placing the weight over the “sit bones” and not the soft tissues.
    • Better hip abduction brings improved posture over narrower saddle seats.

How to Use:

Sitting on the 135DSS Stool

Always approach the stool from the back and stand to one side.

Swing other leg over the back of the stool and be seated. (When swinging your leg over the stool, make sure the stool has not rolled away before sitting.)

Lift the adjustment lever until feet are flat on the floor. Thighs should angle downward at approximately 45°

The stool is now at your proper ergonomic height.

Proper ergonomic seated back position: Hips tilted forward, deep low back curve.

Adjust work surface so the user’s forearms are in a horizontal position, or sloping downward at a maximum of 30-40.
