IKEA had some really neat kitchen islands. You can adjust the height to fit your needs.
Mine is a rolling folding kitchen cart I got on sale at a local grocery store with extras. I love it. I can put it away when I have guests, either by rolling it into my sewing studio or folding it up and putting it in the garage.
Unfortunately, I don't see them anywhere anymore. I've even tried online for some friends. If anyone sees them please PM me.
