The Sittris PA (patient chair) provides attributes that encourage patient recovery: a gentle, relaxing therapeutic movement; pressure relief in the seat area to stimulate blood circulation; comfortable support for patients' arms without putting unnecessary pressure on the elbows; easy access to patients for chair-side treatments; comfortable leg positioning while reducing downward pressure on patients' heels; easy to clean surfaces that resist bacterial, viral and microbial growth; and superb lumbar support, effectively "nestling" all patients regardless of height, allowing them to relax and "snooze."
