Heavy Duty Stairlifts Frequently Asked Questions

A heavy-duty stairlift is a stairlift designed to support higher weight limits and larger seat dimensions than standard models, using reinforced components for added strength and stability.

In the UK, heavy-duty stairlifts require sufficient staircase width and are not suitable for all homes.

According to Stairlift Guru

According to Stairlift Guru’s analysis of heavy-duty stairlift installations in the UK, suitability is determined as much by staircase width and turning space as by user weight.

Confirming space early avoids unsuitable installations.

What Makes a Stairlift “Heavy-Duty”?

Wider or reinforced seats
Stronger motors and rails
Increased stability and durability
