Compact dimensions
The M4 Nexa is designed for users of smaller stature who need powered anterior tilt, tilt, recline, elevating leg rests and seat elevation. Permobil says the chair offers a 15-inch seat-to-floor height with anterior tilt, seat widths from 12 inches and seat depths from 10 inches. By comparison, the M3 Corpus starts at 17.5 inches in seat-to-floor height, 17-inch width and 14-inch depth.
Maneuverability and seating
The chair has a 21.1-inch turning radius and a 21.5-by-33.5-inch base, compared with the M3’s 20.5-inch turning radius and 24-by-35.5-inch base. It also uses Permobil’s Connect connectivity platform and introduces the Nexa seating system. The company’s press release says Nexa follows the body’s natural pivot points and may reduce powered-positioning movement by 25% to 50% versus its current Corpus system.
Regulatory path and plans
The M4 Nexa is expected to become available through the U.S. Department of Veterans Affairs after anticipated FDA 510(k) clearance in early October 2026. That clearance remains anticipated as of October 2. Permobil plans broader commercial availability in the United States and Canada for January 2027, subject to regulatory and market-access requirements.
