Dental Ergonomic Product Reviews


PLEASE NOTE: We do NOT sell dental stools. We provide product reviews only.

Products are evaluated on ergonomic features only. Evaluators include practicing clinicians, faculty, and Ms. Valachi. For more information about the review and evaluation process, click here.

Bethany Valachi's book, "Practice Dentistry Pain-Free: Evidence-based Strategies to Prevent Pain & Extend Your Career" provides important guidelines you should know prior to purchasing an operator stool: dental stool ergonomic features, adjustment and impact on your musculoskeletal health. Download an excerpt from Chapter 6 - OPERATOR SEATING EXCERPT.

Proper cylinder height, seat pan depth, seat tilt, backrest adjustability and waterfall edge are key to proper postural support and avoiding pain syndromes. The seat pan depth and cylinder height should allow you to maintain backrest contact with feet firmly on the floor, thighs sloping downward. Too short a cylinder can cause rounding of the low back, with subsequent low back pain. Most vendors will let you trial the chair for at least 2 weeks.

Crown Seating Virtu Stool

Tel: 800.417.4122
Retail Price: $795

Features:The new Virtu Stool by Crown Seating offers several new innovative ergonomic concepts not found in other dental stools:  The seat moves with the operator via a patented new technology, the mesh prevents sliding forward when the seat tilts, as well as allows 'breathing' of material, and the backrest is uniquely contoured to fit the back.  Evaluators rated the contoured mesh backrest excellent and extremely comfortable.  (On a personal note, I now use this stool as my primary office chair, as the backrest is the most comfortable I have found, and has also helped eliminate an episode of back pain.)   Several evaluators rated the 'free float' adjustment of the stool as good and quite useful to vary one's seated posture.  Available in multiple cylinder heights to accomodate most users.  Available with fixed, adjustable armrests, which were not evaluated in  these trials.

Brewer 9100B Series Stool

Tel: 800.558.8934
Retail Price: $1512

Features: A sleeker, smaller version of the previous, larger 9000B model. Lighter weight enables easier mobility in the operatory. Seatpan is shallower and well-suited for short to medium height operators. Evaluators rated the movable armrests as excellent. The stool features easy, synchronized tilt of seat and backrest with single lever, and cylinder is available in 3 heights. Works well for medium to tall operators. Notched seat helps gain closer access to patient chairs with small headrests. Backrest was rated fair in comfort, as the upper portion tended to push forward into the thoracic spine.

Swedish Seating System by RGP

Tel: 800.522.9695
Retail Price: $752

Features: Highly contoured, bowl-shaped seat requires that the operator's buttocks fit the shape well, or else they tend to slide forward on it and lose contact with the backrest. I have found this fits a taller, slender body-type best. Synchronized tilting seat pan & backrest. If the seat does not fit well, ask to trial the alternate seat pan that is not so highly contoured. Armrests are hydraulic and telescope in/out. Many operators remove the hydraulic armrests or keep the left side only.

The Health Chair

Tel: 505.797.3019
Retail Price: $1595

Features: Designed by a dentist, chair features two highly adjustable seatbacks to adjust the top of the back and the thoracic spine independently. Research shows frequent re-positioning of the back is healthy for static jobs. Chair size fits larger operators well. Larger size may be difficult for use in small operatories. Has highly adjustable armrests; no tilting seat pan.

Global Microsurgeon Chair

Tel: 800.861.3585
Retail Price: $1050

Features: Designed to be used in conjunction with the Global microscope. Has tilting seat pan & backrest.
Armrests adjust up, down, in and out and in front of operator (when positioned in front of the operator, armrests encourage slouched posture with rounded shoulders). Evaluators rated the ease of adjustment and lumbar support as excellent.  Comfort was rated fair/good, due to a firm seat that is not highly padded.

Crown Seating C30H Chair

Tel: 800.417.4122
Retail Price: $557

View the Crown Seating video on Operator Seating

Features: An innovative hybrid between a traditional stool and saddle stool. Triangle-shaped seat allows operators to sit at an ergonomically correct angle with thighs angled downward-without the expense of a tilting seat pan. Evaluators rated the small backrest excellent in terms of ease of adjustment and comfort. Access and adjustability were also rated excellent. This stool is especially well-designed for shorter operators (ask for a short cylinder) and hygienists. The price is right!

Crown Seating 80 Series Dental Stool

Tel: 800.417.4122
Retail Price: $1484

View the Crown Seating video on Operator Seating

Features: Ergonomic saddle-style seat. Highly innovative design supports the operator during active sitting and while resting. Tilting seat and backrest are synchronized to move with the operator, preserving proper spinal alignment. Stool requires 20" of operating space around patient's head due to tilting backrest. Optional armrests are available.

Royal RO44 Operator Chair

Tel: 425.743.0988
Retail Price: $620

Features: Shallow seatpan (14 1/2" D X 17" W) works well for many shorter dentists & hygienists. Seat & backrest tilt with one lever. Lumbar support size fits most operators well.


By increasing the hip angle, saddle stools allow the closest positioning to the patient, especially at the 8-9:00 positions. Pelvic positioning helps reduce low back strain and, by design, the saddle stool facilitates use of the deep postural stabilizing muscles. Excellent for small operatories, since they move around very easily.

Scandex Saddle Stool

Tel: 888.245.1367
Retail Price: $544 - $559

Features: The Bjorn Series 400 stool was evaluated. Medium width, highly padded tilting saddle is a  combination that fit a majority of evaluators well. Rated excellent for comfort and ease of use.  Good for patient access. Armrests are now available for the Bjorn saddle stool. Direct sales only.


Bambach Saddle Stool

Tel: 800.328.2335
Retail Price: $645-$995

Features: Narrow, well padded tilting saddle seat fits operators with small frames well. Bambach now also offers a larger saddle seat to accomodate larger operators. Most evaluators found the optional backrest unnecessary--the size was quite large for most evaluators' lumbar spine.

Salli Saddle Stool

Tel: 800.466.1341
Retail Price: $407 (Salli Pro), $587 (Salli Classic/Twin), $739 (Salli Multiadjuster)


Features: Wide, tilting saddle seat is also available in a split seat design (shown) to help improve comfort--especially for men. Additional padding for the stool is available upon request, however this manufacturer does not recommend thick padding as it may transfer the body weight away from the sit bones.


Crown Seating Saddle Stools

Tel: 800.417.4122

Retail Price: $663

Features: The C90SB (left) and C90SS (right) were received for evaluation.  Armrests are available on both stools.  The C90SB is heavily padded and was rated excellent for comfort by smaller operators probably due to narrow saddle shape. The C90SS was evaluated with armrests by male dentists.  The comfort and ease of adjustment was rated good.  The armrests were rated excellent+.  One comment on the telescoping armrests was how much further these armrests extended than other stools evaluated thus far.
