Designed for Smaller Users
Permobil says the M4 Nexa brings functions from its larger Corpus power chairs to a smaller frame. The company designed it for users with complex seating needs, including adolescents and smaller adults who may otherwise need full-size equipment to access powered tilt, recline, leg elevation, anterior tilt and seat elevation.
Dimensions and Maneuverability
The chair offers a claimed 15-inch seat-to-floor height with anterior tilt, while seat widths begin at 12 inches and depths at 10 inches. Permobil lists a 21.1-inch turning radius and a 21.5-by-33.5-inch base. The comparable M3 Corpus starts at larger seating dimensions and uses a slightly smaller turning radius but a larger overall base.
New Seating System and Timing
The M4 Nexa includes Permobil’s Connect connectivity platform and introduces a seating system named Nexa. The manufacturer says its design follows natural body pivot points and can reduce movement during powered positioning by 25% to 50% compared with the current Corpus system. U.S. commercial availability is planned for January 2027, subject to regulatory and market-access requirements, while Veterans Affairs access depends on anticipated FDA 510(k) clearance.
