Harmar offers a variety of stairlifts—from straight to curved, and basic to heavy duty. We want to make sure you find your perfect fit, and with extra options to really make your lift yours, we’re here to help! Consider your staircase type, your personal needs, as well as those of any household members.

Harmar offers multiple options and accessories. Depending on the model of your lift, you may have the option to upgrade your regular seat belt to a retractable seat belt; or, you may need a key lock to ensure none of your house guests take unexpected trips up and down your stairs. For a smooth, efficient trip up and down the stairs, consider the optional power folding footrest and power seat swivel. Ask your Harmar dealer which accessories would be right for you.

The Pinnacle straight stairlifts are designed to fit any straight staircase without any curves to the structure. With a larger seat and 10.5” folded width, the SL600 is optimal for narrow stairways and offers increased comfort. To avoid any obstruction near doorways, walls, or walkways, add a folding rail to the bottom of your stairlift.

At Harmar, we understand everyone has different needs. We offer three different sizes in our straight stairlifts: SL300, SL600, and SL600HD. The SL300 seat offers a smaller, more compact seat, while the SL600HD can accommodate up to 600 lb and offers a wider, padded chair and larger backrest. Which will best suit your lifestyle and home?

A stairlift is a motorized device that helps people travel up and down stairs with ease. It consists of a chair with a footrest and armrests that travels along a rail installed on the stairs. With easy-to-use controls, the stairlift gently transports the user, providing independence and accessibility for those who seek an alternative to stairs. Designed with safety features like a seatbelt, footrest, and armrests, a stairlift offers a seamless and secure option to navigate stairs, supporting a wide range of needs.

A vertical platform lift is a mechanical device that provides vertical transportation for people who wish to or must remain in their wheelchairs, scooters, or other mobility devices. It functions like a small elevator, moving vertically between different levels, such as from ground level to a porch or between floors in your home. They’re designed to accommodate both indoor and outdoor use, offering a reliable way to move between levels without stairs.

Outdoor stairlifts are designed to be weather-resistant as they’re built with durable materials that can withstand various weather conditions, such as rain, snow, and extreme temperatures. Harmar lifts typically feature waterproof covers, rust-resistant components, and UV protection to prevent sun damage. Regular maintenance is recommended to ensure they remain in good working condition, especially in harsh climates.

Harmar products are available through any of Harmar’s authorized dealers located throughout the United States and around the world.
