I have a chrome wire cart that measures approximately 19"x 16" x 35". There are four drawers and it has wheels. I mostly use it for current projects and it is wonderful. I got it at Costco, but I have seen similar in other places. They look similar to a big chrome rolling shelf things they have in bakeries and such. Much smaller of course. It is sturdy and holds a lot of stuff. I don't really use it to store things, just for the stuff I plan to make at the moment. It is small enough to bring out and work on something, then put away when you are done.
I used to have one that was a bit bigger, but the same type and maker. I used it for big craft fairs. We put grids on the top and had a lot of heavy ornaments hanging on it. It had shelves, not drawers. It was taken apart and put back together for every show. And it held up perfectly.
