“I needed a stairlift because it was so hard for me to go up and down the stairs – I was always afraid of falling. I had to hold onto the banister with both hands and put both feet on each step. Now, I can get up and down the stairs and outside without being so worried!”

“I was looking for a stairlift for my mother – she’s going on 92 years now and she has mobility issues. She loves the straight stairlift from Harmar. Great crew, great installation. Everything was just wonderful. We couldn’t be happier with it.”

“Before getting my SL300, I took my stairs very cautiously. I used to have to count each stair when going down so I don’t miss one. I’m so grateful for my stairlift because I don’t have to dread taking the stairs.”

Factors to Consider before Making a Decision

The Pinnacle straight stairlifts are designed to perfectly fit any straight staircase without any curves to the structure. With a narrower seat and 1” installation from the wall, the SL300 is optimal for narrow stairways. 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 SL600 seat offers a more comfortable chair with a larger backrest, 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?
