What is the weight capacity of a stairlift? 

We have a wide range of products to meet all our customers’ needs for both straight stairs and stairs with turns, so whatever you’re looking for, we’re sure we can help. The weight capacity of each lift is set so that we know you can use our stairlift safely up to that weight. 

Our stairlifts are manufactured to hold 5x their maximum weight limit – they could carry a fully-grown polar bear, so you definitely won’t break it! Your safety is our priority, so we set the weight limit to ensure your stairlift carries you upstairs and keeps working for decades, keeping you moving for longer. The maximum weight capacity of our stairlifts is 25st /158kg, but it depends on the model. 

There are two models of Stannah stairlifts with a higher weight capacity – the Starla and the Siena. Although all our stairlifts can comfortably carry up to 300 lbs (21,4 st /136 kg), the Starla and Siena straight models have a higher weight limit of 25 st /158 kg.

Stannah stairlifts are made to fit you and meet all your needs. They can carry you safely up and down your stairs without you having to worry about reaching their maximum weight limit. You may be picturing a robust-looking, bulky chair that takes up the width of your staircase. That’s not the case when you buy a Stannah stairlift. Our stairlifts have all been designed, first and foremost, to be safe. 

Their safety features make you feel secure while you glide up the stairs. But they’ve also been designed to look good. We’re manufacturers, but we’re also people.

Our chair lifts are also customizable, you can choose the fabric and colour of the upholstery, and make sure your stairlift looks exactly the way you want it to look in your home.

Although the maximum capacity of our stairlifts is 25 st /158 kg, the type of stairlift you choose according to your individual needs might have a slightly different limit.

The Siena is our most popular stairlift thanks to its simplicity and practicality. It’s also one of our most adaptable stairlifts, which means that as well as the many colour choices and options of upholstery, it can be installed on both straight and curved stairs. 

The Siena is one of our heavy duty stairlifts with a maximum capacity of 25 st /158 kg for straight stairs. For curved stairs, the limit is 21,4 st /136 kg.

The Starla is our most customizable stairlift thanks to the different options of upholstery and wood trim we offer you. You even get to choose which type of wood you’d like on your stairlift if you want it at all! Part of the versatile nature of the Starla is that it can also be installed on both straight and curved stairs, so depending on what your stairs are like the weight capacity of your Starla will vary.

 The Starla is one of our heavy duty, or bariatric lift models, with a maximum capacity of 25 st /158 kg for straight stairs. For curved stairs, the limit is 21,4 st /136 kg.
