Dear Savvy Senior: Can you recommend some good stair lift companies? I have a difficult time getting up and down the stairs and am interested in purchasing a stair lift for my house but could use some help choosing one. — Arthritic Ann

Dear Ann: A good home stair lift is an excellent solution for those with mobility challenges who have trouble with steps. A stair lift will carry you up and down the stairs in a safe seated position, providing easy access to the second story or basement level of your home.

To help you choose a quality stair lift that meets your needs and budget, here are a few shopping tips, along with some top-rated companies that make them.

Types of lifts

There are two basic types of stair lifts that are sold today: straight and curved. The type you need will depend upon the design of your staircase.

A straight stair lift is one that travels in a straight line up a flight of stairs uninterrupted by landings, bends or curves, and costs between $2,500 and $5,000 installed. Curved lifts, however, are much more elaborate and will go around corners, bends and changes in direction. Curved lifts are much more expensive, typically running $8,500 to $15,000 or more depending on the complexity of the installation.

You also need to know that all stair lifts mount to the stair treads, not to the wall, so they are very sturdy and can be installed in almost any home.

If you are a large person, you may need to get a heavy-duty lift with a wider seat and bigger lifting capacity — all companies offer them. Or, if you’re tall, find out about raising the seat height during installation.

Most stair lifts available today also have seats, armrests and footplates that fold up out of the way, and swivel seats that make getting into and out of the chair easier. They also come with standard safety features like seatbelts, braking systems and footrest sensors, push-button or rocker- switch controls located on the armrest for easy operation, and “call send” controls which allow you to call or send the unit to the other end of the stairs. Make sure the lift you choose has all these features.

Depending on the company, you may also have the option of choosing between an electric (AC) and a battery-powered (DC) stair lift. Battery-powered units charge at the base station (some recharge anywhere on the track) are quieter, smoother and better than electric lifts and will work even if there’s a power failure in the home.

Where to shop

While there are many companies that make and sell stair lifts, two of the best, based on reputation and customer satisfaction ratings, are Bruno (Bruno.com, 800-454-4355) and Stannah (Stannah-Stairlifts.com, 888-465-7652).

Unfortunately, original Medicare does not cover stair lifts nor do Medicare supplemental (Medigap) policies, but some Medicare Advantage plans may help pay. There are also many states that offer Medicaid waivers that will pay for lifts to those that qualify, and the VA offers cash grants to veterans with disabilities for home safety improvements.

To save some money, you may want to consider purchasing a used or refurbished model. Or, if you need a stair lift for only a short period of time, consider renting one. Most companies offer these options, and many offer financing programs too.

To get started, contact some stair-lift companies who can put you in touch with a dealer in your area. All dealers provide free in-home assessments and estimates and can help you choose an appropriate lift.
