Description

KingChair D39 Bariatric Electric Wheelchair – 300kg Heavy-Duty Folding Power Chair

The KingChair D39 is a 300kg bariatric electric wheelchair — the highest weight capacity in our range and one of the strongest folding power chairs available in New Zealand. Built on a robust one-piece frame, it is a genuine heavy-duty electric wheelchair for larger users who need real load-bearing strength without sacrificing modern features, comfort or app control. If you have been searching for a bariatric wheelchair, a heavy-duty motorised wheelchair, or an electric wheelchair for a heavier user in NZ, the D39 is engineered for exactly that.

With dual brushless motors, off-road tyres, full suspension and a 300kg capacity, it combines maximum strength with a smooth, controlled, comfortable ride.

Built for Maximum Load-Bearing Strength

The D39’s one-piece frame construction gives it an exceptional 300kg weight capacity — built for heavy-duty everyday use and suitable for larger users that most folding power chairs cannot safely support. It is the flagship of our bariatric range: where our other bariatric chairs are rated to 180kg and 250kg, the D39 takes capacity to the maximum.

Advanced Control & Connectivity

At the heart of the D39 is the Wave controller, offering precise, smooth control. Manage the wheelchair through the dedicated app or the included wireless remote, switch easily between manual and electric modes, and drive with confidence thanks to anti-tilt wheels that keep you stable on slopes.

• Wireless remote support – drive or reposition the chair remotely
• App control – manage settings from your phone
• OTA wireless upgrades – keep the chair’s software up to date
• Remote locking – lock the chair and customise settings

Comfort & Suspension

Front and rear independent shock-absorption deliver a smooth ride, while high-strength off-road tyres handle a range of terrains. The D39 also features fold-away footrests, foldable anti-flip wheels for added security, a spacious storage compartment and a 3D one-piece breathable cushion for all-day comfort.

• Dual charging modes – charge on-board, or remove the lithium batteries to charge separately
