Specialised Models

Stair Lift Weight Limit: is there a Maximum?

Some manufacturers offer specialised stairlifts that can support more than 272 kg (42 stone). These models are less common and may require custom manufacturing to meet specific needs.

Some more specialised stair lift types that may suit you are:

  • Platform Stair lift
  • Standing Stair lift
  • Elevator Lift

Platform Stair Lift

Platform lifts, also known as Wheelchair lifts, a chair lift for stairs or vertical platform lifts, are a vital solution for some where a conventional stair lift is unsuitable. Unlike stairlifts, which are designed to transport individuals seated in a chair along the contour of a staircase, wheelchair lifts accommodate users while they remain in their wheelchairs.

Platform Stair lifts of wheelchair lifts can have weight limits that exceed 340 kg (53 stone).

Standing Stair Lift

A standing stair lift caters to individuals who face difficulty navigating stairs due to balance, joint, or flexibility issues but can stand upright safely. Unlike traditional seated stairlifts or wheelchair lifts, a standing stair lift features a small platform and a secure, upright posture support, allowing users to ascend or descend stairs in a standing position.

Standing Stair lifts typically have a weight limit of 136 kg (21 stone).

They are an ideal option for a narrow staircase where traditional seated stair lifts cannot fit, offering an alternative that enables individuals to maintain their independence and access different levels of their home or public buildings without assistance. By addressing the unique needs of users with limited mobility, standing stair lifts enhance quality of life and facilitate safer, more comfortable home environments.

Elevator Lift

An elevator lift, often referred to simply as an elevator, is a permanent fixture in multi-story buildings designed to transport people or goods between floors efficiently and safely. Unlike stairlifts or wheelchair lifts that are added to existing staircases, elevator lifts are integrated into the building’s structure, offering a seamless solution for vertical mobility.

An Elevator Lift can have weight limits between 907-2,268 kg (142-357 stone).

Important Considerations

Accuracy is Key

It’s essential to have an accurate understanding of the user’s weight to select a stair lift that provides the necessary support. The weight capacity of the stair lift should meet or exceed the user’s weight to ensure safety and longevity of the equipment.

Consultation and Customisation

When in doubt, consult with the stair lift supplier or manufacturer. They can provide detailed advice on which models are best suited to the user’s weight and other specific requirements.


For users near the upper limit of a stairlift’s weight capacity, or for those who require additional space or features, customisation options are available.

Future Proofing

Consider the long-term needs of the user. Opting for a stair lift with a higher weight capacity can be a wise choice to accommodate any future changes in the user’s mobility or weight. By considering the user’s weight and consulting with professionals to find the right stair lift model, you can ensure a safe, comfortable, and reliable mobility solution in the home.


Always prioritize safety and suitability when selecting a stair lift, ensuring that the chosen model adequately meets the specific needs of the user.
