There will be some essential shelves: top, bottom, and usually one in the interior. We define shelves in the assembly manual as either fixed or adjustable. Fixed shelves must be assembled to ensure the structural integrity of your unit, but we try to keep in mind that where one person might want to put bows and birthday cards, another might want to vertically store wrapping paper. There are multiple spaces to rearrange, remove, or add extra shelves. We may even have them available for sale if you want additional shelves.
