Heavy-duty stairlifts
More room, more support, more capacity
Heavy-duty (bariatric) stairlifts pair a wider, sturdier seat with a higher weight rating — so larger users can ride in genuine comfort and confidence.
Designed for comfort
Built wider and stronger
Everything is reinforced — the rail, carriage, and motor — to carry more weight smoothly and safely. The seat is broader and more deeply padded, with generous armrest spacing, while the ride stays as quiet and gentle as our standard lifts.
- Higher weight capacity, up to 400–500 lbs
- Wider, deeper padded seat and armrests
- Reinforced rail and heavy-duty motor
- Powered swivel and footrest options
- Available for straight and curved staircases
