I'm on the lookout for a small cabinet armoire to put in my office in which to house my small collection of books and office supplies. The length, width, color, wood doesn't matter so much as it has to have doors that can close.
The simple act of closing the doors on something as basic as some books, files and paperwork can be powerful. It's a mental vacation from items that remind you of work, study, to-do lists, receipts and bills. When the doors are open, it's time to work; when they are closed, it's time to relax and play.
Besides, open shelves collect dust.
