The Helix Mobile Stairlift is a portable, battery-powered stair climbing chair designed for curved, rounded, spiral and straight staircases. Its independent motorized crawler tracks are designed to maintain stable contact while navigating turning and irregular stair layouts that standard straight-stair mobile stairlifts cannot accommodate.
Unlike permanent rail-mounted stairlifts that require custom installation and home modifications, the Helix provides portable seated stair access without permanent installation. The user remains seated in an upright position while an operator controls powered movement up or down the staircase.
With a 400 lb weight capacity and climbing range of up to 120 flights per charge, the Helix is designed for frequent stair use in homes, caregiving environments, recovery situations, travel and rental applications.
The Helix features a flexible crawler track system designed for curved, rounded, spiral and straight stairs. Its independent drive tracks help maintain contact around turns and changing stair geometries. The unit can operate on wood, carpet, tile, concrete and most common stair surfaces when properly secured.
The Helix offers an alternative to permanent stairlift systems for homes where installing a rail-mounted lift is impractical or undesirable. Its portable design allows the unit to be used when needed and stored or transported when not in use.
When stair access is not required, the Helix folds for storage and transportation. Its portable design makes it suitable for families who travel, multi-location caregivers, rental programs and situations where a backup mobility solution is needed.
The Helix combines an upper control handle with lower assist handles to provide flexibility during operation. Its four-wheel transport system also allows the unit to move across flat surfaces before and after stair travel.

For homes and facilities with curved, rounded, spiral or straight staircases, the Helix combines portable design, powered crawler tracks and a 400 lb capacity in one mobile stairlift. With up to 120 flights per charge, a removable battery, folding construction and operator-controlled movement, the Helix is designed to provide portable stair access without permanent installation.
The Helix is designed for curved, rounded, spiral and straight staircases, making it more versatile than stairlifts intended only for straight stairs. Its independent motorized crawler tracks are designed to maintain contact while navigating turns and changing stair geometries. It can operate on common surfaces such as wood, carpet, tile and concrete when properly secured.
The Helix has a 400 lb weight capacity, making it suitable for users weighing up to 400 lbs. The unit itself weighs 65 lbs and uses a high-grade aluminium frame. The stated capacity should not be exceeded, and the operator should ensure the rider is properly positioned and secured before powered stair travel.
The Helix uses independent motorized crawler tracks designed to maintain stable contact with curved, rounded and spiral stair layouts. An operator controls the powered movement using the upper control and lower assist handles while the seated rider remains in an upright position. The automatic braking system is designed to provide controlled movement during stair ascent and descent.
The Helix provides up to 120 flights of stair travel per charge using its rechargeable lithium-ion battery. The battery is removable and includes a charge-level display, allowing it to be removed for charging when convenient. Actual battery range can vary depending on the user's weight, staircase configuration and operating conditions.
No. The Helix is a portable mobile stairlift that does not require permanent rails or structural home modifications. Its folding design allows it to be stored or transported when not required, making it suitable for homes, caregiving environments, travel, rental programs and backup stair access. The unit can also be moved across flat surfaces using its wheels.
The Helix has a stated minimum landing area of 38 × 38 inches. Its turning radius is listed as 44 × 44 inches with the tracks open and 35 × 35 inches with the tracks closed. Staircases and landings should be assessed beforehand to ensure there is adequate clearance for positioning, turning and controlled operation.
