This cart is wonderful.  But, unfortunately, the brackets upon which the interior shelves rest are not sufficiently large to hold the shelves in place when the cart is rolled over thresholds.  My island lives in my mud room and is filled with all the items needed for a cook out for twelve.  When we moved it from the mud room to the patio, we rolled it over the threshold to the exterior door to the patio, and all the shelves and their contents fell down.  Fortunately, the serving pieces, which are earthenware, had already been taken out, leaving only the melamine dinnerware, which, of course, did not break. The next day we purchased larger, stronger brackets and installed them to support each shelf.
