For everyone asking about dimensions.... I'm in work right now so don't have the cabinet in front of me. If you look at the picture of the cabinet, there are seven slots which I'm guessing are 7-8" wide based on the fact that I used a 5" wide ruler to fold the fabric and, 7 x 8" = 56" or about five feet wide. I believe it's just over six feet tall.
This particular cabinet can be broken into three pieces: the top, pull-out shelf, and bottom. It's heavy guage so it took all of my and Bob's strength to get the top and bottom pieces upstairs to my sewing room. The pieces screw together which makes the unit very sturdy.
As I said, the doctor still has another cabinet which, if I remember correctly, is about the same width but a little shorter. That one has dividers that can be repositioned on the shelves.
This was an opportunity that fell into my lap. But, I have to believe there'll be other similar cabinets some where out there. Good luck on your hunt!
