SL600 Pinnacle Premium Straight Stairlift

The Pinnacle SL600 is one of the most reliable and user friendly straight stairlifts available today. Its ultra narrow profile keeps stairways accessible, the ride is exceptionally smooth and quiet, and the no grease track means less mess and less maintenance for homeowners. With thoughtful options like a power swivel seat and power footrest, it’s designed to make every trip up and down the stairs safer and more comfortable.

"I never realized how much confidence a stairlift could give me until I tried the SL600. It’s smooth, easy to use, and doesn’t get in anyone’s way. It has truly changed my daily routine for the better."" – Anita G., Ashburn, VA
