Stair Chairs for St. Peters Homes
St. Peters is largely made up of two-story and split-level homes built from the 1970s onward. Straight staircases are the norm, and a straight stair chair is often the quickest way to make the upstairs bedrooms or lower level easy to reach again.
A stair chair lets you sit down at one end of the staircase, ride smoothly to the other floor and step off, so bedrooms, laundry rooms and basements stay part of everyday life. For many St. Peters homeowners, it's the difference between moving and staying in the home they love.
Straight and Curved Stair Chairs in St. Peters
The right stair chair depends on the shape of your staircase. We install both types throughout St. Charles County.
Straight stair chairs
For staircases that run in one straight line from floor to floor. Usually the simpler installation.
Curved stair chairs
For staircases with a landing, a turn or a change in direction. The rail follows your stairs.

How much does a stair chair cost in St. Peters?

Is a stair chair the same as a stair lift?
Yes. "Stair chair," "stair lift" and "chair lift for stairs" all describe the same thing: a seat that travels along a rail mounted to your staircase. We install them in homes across St. Charles County and the rest of our service area.
My St. Peters home has stairs with a landing or a turn. Can you help?
Yes. Staircases that turn, have a landing partway up or change direction need a curved stair chair, which uses a rail shaped to your stairs. We install both curved and straight stair chairs in St. Peters.
