Good for full height bookcase, bad for half size.Anonymous reviewerI purchased this 2 weeks ago along with a half height BILLY Bookcase. I have pictures on the wall and wanted to put a half size bookcase and an extension above that to maximize the bookcase space, while preserving the wall space I needed for the pictures I have on the wall. Turns out the BILLY Height extension unit is not compatible with the Half Height BILLY Bookcase. Whats missing is the last part where it asks you to put the screws into the holes on the top of the sides of the BILLY which are missing from the half height BILLY. So if you want to attempt this, be prepared to measure the exact spot where you need to attach the extension to and drill your own pilot hole into the half size BILLY. I wish ikea would've done a compatibility guide as I was planning this build based on the information on their website.4

What is veneer?

A veneer is a thin wooden sheet fixed on things like particleboards to add a durable surface and a natural wood look – so we enjoy the many benefits of wood without using solid wood. The most common veneer types are birch, ash, oak and beech and we’ve made a special UV lacquer that helps preserve the wood's natural structure. A benefit with a slightly thicker veneer is how you can repair and sand the surface if it’s damaged to give furniture a longer and more beautiful life.
