Red Door is located on Main Street in Simpsonville and is hard to miss.. it lives up to it's name. :) Unassuming on the outside, it is a small white house with, yes, a red door. The inside is what counts though. They have a wonderful selection of used furniture in a small space and it's a place to frequent often, just to keep up with the changing inventory. The staff is very nice and willing to help. Parking is a little tight, but you don't have to fight crowds which more than makes up for it.
