Front-Wheel Drive for Superior Control and Stability

Powering the front wheels lets the chair pull itself through tight spots and over obstacles instead of being pushed from behind. This setup delivers:

  • Precision Indoor Navigation: Front wheels take the lead, enabling the chair to pivot smoothly in crowded hallways and around furniture
  • Effortless Curb Engagement: Driven front wheels make first contact with curbs and door thresholds, working alongside the 4Sure™ suspension to lift and roll over bumps with minimal buildup
  • Confident Uphill Traction: With the drive force upfront, the chair grips inclines securely, reducing tip-back and keeping forward momentum on ramps and slopes
  • Close-Quarter Accessibility: A compact front-wheel footprint allows users to get closer to tables, counters, and vehicles, simplifying transfers and daily tasks

Altogether, front-wheel drive delivers the perfect balance of indoor agility and outdoor confidence, making it an excellent choice for users who need nimble maneuvering and dependable performance.

Captain-Style Seating for Superior Ergonomics and Support

By cradling users in an adjustable, ergonomic layout, the captain-style seat promotes all-day comfort and healthy posture. This design offers:

  • Ergonomic Lumbar Contouring: A built-in adjustable lumbar pad supports the natural curve of the spine, reducing lower-back strain during extended use
  • High-Back and Headrest Support: The integrated high-back cushions the upper spine, while an adjustable headrest alleviates neck tension and enhances relaxation
  • Custom Seat Angle and Depth: Easily fine-tune seat tilt and depth to match personal posture needs, optimizing weight distribution and pressure relief
  • Plush, Adjustable Armrests: Soft, pivoting armrests adjust in height and width, giving forearm support that adapts to activities—from typing to dining

Together, these features make the captain seating option an ideal choice for anyone prioritizing ergonomic support, fatigue-free mobility, and all-day comfort.
