The XSTO M4: Smart Mobility Designed Around Your Life.

The XSTO M4 is a next-generation power wheelchair designed for individuals who refuse to be limited. Its intelligent self-balancing system keeps you level on slopes, curbs, uneven paths, and daily terrain-automatically.  

Seat height adjusts from 13.66" to 25.59", letting you transfer more easily, sit at eye level, or reach higher surfaces with less strain.

If you want a chair that thinks, adapts, and lets you move with stability and confidence, the award-winning M4 delivers comfort, control, and freedom in every environment.

Intelligent Self-Balancing on Slopes and Obstacles

The XSTO M4 uses an automatic self-balancing system that adjusts the seat angle when going up or down slopes or over obstacles. This helps reduce sudden shifts and keeps the user more steady on uneven terrain.

Adjustable Seat Height and Tilt Angle for Enhanced Support

The XSTO M4 Adjustable Power Chair features a dynamic seating system that allows users to adjust both the seat height and tilt angle with ease. These adjustments promote proper posture, improve pressure distribution, and make everyday transfers and positioning more convenient.

360° Steering With App Control

Mecanum wheels let the device turn 360° in place for easy maneuvering. You can control it using the joystick, or use the optional smartphone app for remote operation.

Folding and Modular Design for Easy Transport

The XSTO M4 Foldable Power Chair folds using a one-key system for quick storage. Its modular build lets you separate the chair into three parts, making it easier to lift and place in most car trunks. 

Power That Keeps You Moving

The XSTO M4 comes with a high-capacity 25.55V 15.5Ah lithium battery, offering up to 11 miles per charge for everyday travel.

Happy Customers

★★★★★

What features I like about the M4 are that you can raise and lower the height, tilt the chair, and take it on the sand at the beach — all features that my current chair can't do.

★★★★★

M4 is my favorite power chair ever. Both an elevating seat and a reclining seat feature make me enjoy the warm sunshine, and its weight is lighter than most other elevating chairs — cool!

★★★★★

Being elevated 12 inches and remote control is amazing! Nice quality chair, great extra features. The XSTO M4 is very well made and offers me a smooth and quiet driving experience.
