The Orbital Microsurgical is a full ergonomic support system for the operatory.

The Orbital Microsurgical (MS) is a larger version of the Orbital Surgical. Ideal for higher standing environments and microsurgery.

An advanced design

The low center of gravity 4 wheeled base is made of powdercoated 1/2 steel plate, which adds weight for stability.

Foot pegs give an alternative location for foot placement.

This base comes complete with high quality aluminum shielded Sheppard urethane Casters.

The chest support is height adjustable and was made as thin as possible to minimize setback from the patient.

Height adjustments are made by backing off the knob at the front of the pad, sliding up or down and tightening the knob back into the detent, at the desired height. An upholstered protective cover is also supplied.

The seat incorporates a unique slide and tilt system. Tilt position can be adjusted to achieve an optimal (posture perfect) curvature of the spine using the large micro adjustable knob at the back.

This neutral spine position relieves the tension of the back muscles allowing the neck and shoulder muscles to also relax. Seat slide (set-back) is adjusted using the two pins on the seat track assembly.

Hands-free height adjustment is operated by a foot pedal conveniently located at floor level allowing the user to maintain sterility.

Armrests ease the tension on the shoulders, arms, neck and back helping to prevent occupational health problems.

Two independently adjustable arm rests are mounted on an easily installed bracket.

The arm rests glide effortlessly on bearings and travel limiters ensure that they remain in the working field.

The optional hydraulic foot pump makes it easier to adjust your height while seated.

Simply pump the lever half way to go up and press fully to go down.

The optional main post tilt adjustment allows you to further optimally position yourself.

Adjustment are made using the knob at the back of the post.


We also build custom built chairs meeting size and height requirements to suit your needs.

Orbital Chairs look best in black, but custom color options are available.
