“I couldn’t be happier with the Pinnacle. I’m so glad I made this choice for my home. I feel safe going up and down the stairs again, and it’s never in the way for my grandkids!”

“I used to be the one to bring the laundry up to the second floor. But now that my wife can use her Pinnacle, she’s more than happy to ride upstairs with some fresh bedding or towels in her lap.”

“My husband and I take turns using our stairlift. Since we were both athletes, our knees aren’t what they used to be. So, the call-send feature on the Pinnacle’s remotes is a lifesaver! If he rides it up to the second floor, I can call it right back down to me when I need it.”


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 offer 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 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?
