You might have other questions too:
You might worry about the damage a stair lift installation might do to your home, specifically to the walls. Actually, stair lifts are usually fitted to the steps or treads on the staircase and run on a rail, thereby sparing your walls any damage.
What if there’s a power cut? Stair lifts run on two 24v batteries which are charged by the mains electricity. So the stair lift will still be operational, regardless of whether there is mains power or not.
Will a stair lift be able to bear your weight? Most stair lifts will be able to bear a maximum weight of around 19 stone. For example the Brooks Lincoln Straight Stair lift. There are other makes of stair lifts such as the MediTek HD (Heavy Duty) which is able to bear weight up to a maximum of 25 stone, also known as the D160 Deluxe Stair lift.
If you’re up stairs and the stair lift is down stairs what then? This is easy; you can recall the stair lift using a remote control.
