BILLY Height extension unit, birch veneer, 32x11x14"

It is estimated that every five seconds, one BILLY bookcase is sold somewhere in the world. Pretty impressive considering we launched BILLY in 1979. It’s the booklovers choice that never goes out of style.

Great for adding extra shelvesHalWe have added 2 toppers to each off he bookcases. Easy to assemble And attach. Looks great!5
Good productJamesGood product5
Get what you pay forDeboraIt’s an easy item to assemble just wish they used metal parts instead of plastic. The little circles you are suppose to tighten break so easily.5
Surprising!!SallyWe were very surprised to see one side of the back piece was a different color than the rest of the unit. It was all white the first three we bought!4
Extension cabinetSusanThese extension cabinets brought my cabinet up to the ceiling in my dining room which made the room look taller! We love the look and the ease of putting everything together!5
Fits an old billy shelfTakiyahFits an old billy shelf we had perfectly.5
Billy extensionJoelleGreat product5
Worked as plannedJohnny43It fit perfectly on our existing Billy book case5
Daca1434Really adds to the Billy bookcase5
Great ideaEssayons121I bought them to be extensions, but they would work due to height restrictions. I ended up using them as additional shelving in the closet.5
FantasticGranny9Did exactly what thy were suppose to. Extend the height of the bookcases.5
Wonderful Product!NetzivI bought this to add a shelf to my existing BILLY bookcase. It fits practically seamlessly. I thought I would have to screw on brackets to attach it to the bookcase, but there were already built in holes for the included attaching screws. My only regret is that I don't have enough room above the unit to go higher. This product really does what it is supposed to. Thank you Ikea!5
i dont understandhchfdhf8585Better than Billy the bookcase but still WHACK. No easy installation and just confusing directions.1
Easy installGJCOThis is a great feature especially if you have too many items for your bookshelf. The extra row will allow us to hold more of our books, and it blends nicely with the original shelf (which we got over 10 years ago). Reasonable price.5
A great shelf extensionTrixie4300Happy to have an additional space for my shoes.5
Doesn’t lineup rightTocam2The Billy does not look right because when you use the wall anchor it creates a gap between the two pieces of furniture3
Great ideaDfourGreat way to extend our bookcases and have even more room for all our books.5
Love BUTLynnielinnie8THERE IS NO WAY TO ATTACH THIS TO THE WALL WITH ONLY 3” clearance to the ceiling. There are only two attachments in the front of the top cabinet, none in the back, so this is not so secure eiher. There should also be a way to attach one bookshelf to the next one. I have a big gap at the top i cannot squeeze closed. There is a half inch gap in the back short of attaching to the lower cabinet.3
