There will be some shelves that are essential: top, bottom and usually one somewhere in the interior. We define shelves in the assembly manual as either fixed or adjustable. Fixed shelves must be assembled, 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 more.
