When we decided to design a stair climber three years ago, we did it because we felt like we had an opportunity to offer the same Jacobs Ladder technology in a stair machine. However, today, there are a number of stair climbers out there, some good, some not so good. The Stairway offers a self-powered, self-paced workout. Just like on Jacobs Ladder, you control your own speed. It has a lower step height than other commercial stair climbers and a lower ceiling height requirement. It has a normal 8.5 “ step with 4 stairs visible to the user. It carries a 4 Year Parts, 1 Year Labor Warranty and is a lower cost than other commercial stair machines.
