Futuristic Electric Wheelchair M4: A Superior Model with Elevation Function and Smart Seat Angle Adjustment on Slopes

■ Introduction In recent years, electric wheelchairs have evolved remarkably, greatly contributing to greater independence and mobility in daily life. Among them, the “Xsto M4” has gained particular attention. This model, capable of climbing stairs and overcoming large gaps, has been a topic of interest for several years. However, the lack of a proper distribution and support system in Japan had previously made it difficult to offer the product to customers.

■ Reliable Distribution and Support System Established Although the Xsto M4 was an appealing product in itself, we had refrained from offering it to customers due to the absence of infrastructure for spare parts supply, price transparency, and repair request procedures in Japan. In fact, we have declined to handle other power wheelchair models in the past after discovering that their manufacturers lacked any intention to establish a support system.

However, with the entry of Imasen Engineering Corporation—renowned for its extensive experience in the electric wheelchair industry—the Xsto M4 can now be offered as a trustworthy and officially supported product in Japan.

■ Official Sales Launch by COM Izumiya With Imasen Engineering’s involvement, the distribution, support, and repair systems for the Xsto M4 are now fully established. COM Izumiya is proud to announce that we can now offer this product to our customers with full confidence. Our mission is to eliminate customer concerns and provide reliable support throughout the usage period.

■ Key Features of the Product The Xsto M4 is a next-generation electric wheelchair packed with advanced features:

• Automatic Seat Angle Adjustment on Slopes Detects inclines and adjusts the seat angle in real-time for a safer, more comfortable ride.

• Electric Lift and Tilt Function The seat can be elevated and tilted to match table heights or to access high objects. It also helps maintain comfortable posture during prolonged use.
