Which Exam Chair is Right for You?
Both chairs offer quality construction and full-power operation, with your practice’s specific clinical needs and patient population ultimately determining the most suitable option.
Consider the MTI 463 if you need:
- ADA-compliant seat height measurements and home button for accessibility compliance
- Higher patient weight capacity for bariatric or mixed patient populations (725 lbs)
- Lower minimum seat height (18.75″) for improved accessibility
- Multiple programmable positions (4 + programmable home) for workflow efficiency
- Automatic 3″ footrest extension with ComfortSync™ technology
Consider the Boyd/Global S4000 if you prefer:
- Slightly wider seat width (22″)
- Higher maximum seat height (38″)
