safety must come first, get a chairlift..... many are available on craiglist

Hi,
If only stair case is straight up or down. Isn't there Acorn brand?

I researched chairlifts a year or 2 ago........

ACORNS reputation wasnt real good, they may be importing units from china or some such

Some local char lift suppliers sell used ones at a big discount.......

Elderly person has one installed and dies, or moves for whatever reason.

so the unit is de installed, and sold used toanother user
