Love storage shelves!

I have at least 8 of these throughout my home, most of them I personally put together. They are so easy to assemble and so useful. Besides my books, I have photos, displays and other things that contain my world. I even have 2 in the sewing room! I'm 77 years old and 3 of them were just put together by me last week. At Holiday times, I have a section that gets adjusted for what I want displayed appropriate for the holiday. I love adjustable shelves!

Book it, Danno

Variation on the standard Mainstays bookcase. True white color as always. Looks more expensive than the regular bookcase. Wish they would drill holes for the shelving all the way down from the top to the bottom so that you can adjust the shelves anywhere you want them

Love it!

Here is a do it yourself assembly product that is a joy to put together. The bookcase is not only well engineered and well built but the assembly instructions are easy to follow. I had gotten two of the bookcases and liked them so much I ordered 12 more. What more can I say?
