I think part of the answer depends on what you are able to to.
Are you able to reach high? Bend down and pull totes from under the bed? How much weight can you lift?
A 56 quart size tote full of fabric is heavy.
I have some industrial shelving that stands by itself and the shelves are adjustable. Tennsco is the maker. I needed help to set it up - a 24 x 48 x 84 inch unit. I had to have some of the tall ones cut down to 78 inches.the only tools needed were a rubber mallet and a hammer. These units can be confiigured in various sizes.
