Stoelting Model 83215 Polygraph Chair – Examiner-Tested, Field-Ready
In the context of psychophysiological detection of deception (PDD), maintaining the examinee’s posture and minimizing motion artifacts isn’t just helpful — it’s fundamental. When you’re looking to produce clear, interpretable polygraph tracings, your instrumentation is only as good as the stability of your subject. The Stoelting Model 83215 Polygraph Chair is designed with this reality in mind.
Built specifically for professional examiners, this chair offers a well-balanced combination of ergonomic comfort, durability, and functionality — all while remaining cost-effective. Whether you’re conducting criminal investigations, PCSOT monitoring, pre-employment screening, or internal theft cases, this unit supports the consistency we need in every session.
Designed for Precision-Driven Environments
This isn’t just any chair. The 83215 is engineered to complement polygraph equipment by actively reducing involuntary motion, countermeasure opportunities, and poor positioning. When examinees are well-supported and comfortably positioned, we see the results on the chart — less artifact, cleaner baselines, and better diagnostic outcomes.

Examiner-Focused Features
✅ Built-in Arm and Back Support
Integrated rests help stabilize the thoracic cavity and upper limbs — minimizing movement in the EDA and respiratory channels. This is particularly useful for lengthy exams and critical comparison question phases where examinee motion is a known confounding factor.
✅ Professional and Durable Construction
A powder-coated steel frame ensures stability and a long lifespan, while the eco-leather upholstery delivers a clean, professional look suitable for any test environment — from government labs to private offices.
✅ 180° Gear-Assisted Tilt and Custom Adjustability
You can tilt the chair to fully reclined for certain examinees who need lumbar adjustment or posture correction. The armrest angle and chair height are fully adjustable, which allows for precision sensor placement — especially for cardio cuffs and pneumograph bands. Adaptability is key when working with varied body types.
✅ Comfort Without Compromise
Soft 1.6″ sponge padding across all contact points — the seat, backrest, and armrests — keeps the subject relaxed but properly supported. This promotes a natural resting posture, reducing fidgeting and unnecessary shifts.
