Is the SL300 right for you?
The SL300 is a great fit if your staircase is straight, the rider is under 300 lbs, and you want dependable, safe everyday access without paying for premium extras. If you'd like a larger seat, higher capacity or a lifetime motor warranty, compare it with the Harmar Pinnacle SL600. If your stairs turn or have a landing, you'll need the Harmar UP curved stairlift.
