Devices, systems, and methods for supporting and/or stabilizing a patient can help to position a patient relative to a therapeutic laser beam, for example, inhibiting motion or deflection during a refractive procedure on the eyes, and the like. A stabilizing structural member can support a chair or other patient support near shoulders of the patient, and the member may remain stationary while the chair is driven in a horizontal plane by a linkage. Often, a nominal patient center of gravity is located between the support member and a portion of the patient support which is supported by the linkage to reduce cantilever effects. The member may be rigidly attached to a vertical motion stage which moves the chair at an angle, for example at an angle normal to the horizontal plane.
