Love my book shelf extensions MilinThey look so good and have taken on a whole new look once installing crown moulding. Love love love
Billy ExtensionRobynVery easy to assemble and attach to other Billy pieces. Consistently good design and quality.
Versatile performerWarrenThe extension gives an easy way to make the Billy more versatile so that you can be more creative with a space.
It is easy to install and makes a more dramatic appearance than the stock, shorter unit. It also adds about 1/4 more storage space, so if you have a lot of books or other things to showcase, it makes a real difference.
Overall easy to install. The only negative is that there are additional seams which takes away from a true custom look but that is a fair trade-off. A little trim goes a long way, as they say!
Great bookcases!SusanWe bought five Billy bookcases (3 narrow and 2 wide) with extenders for floor to ceiling storage. Once each case was attached to its neighbor and then the wall it is very solid and looks great. And thanks to another reviewer's great advice we plan to trim it out for a built-in look.
Bought again.TereaHad bought these before, you changed the connectors from metal to plastic. They break easily.
Very versatileRonaldA very solid extension for a Billy bookcase. The back panel is solid instead of thin (like a Billy). Thus this is a very very solid construction that you can use in many other ways.
Stepped UpAllanWhat a clever idea to get your bookcase in the correct proportion to your ceilings. And extra space to boot.
a bit confusing to put together, and I am considered a "handy" person.Stephenexposed cam hardware is not attractive. Possibly provide some plugs to camoflage this exposure.
I'm very pleased with the purchase.MaximMy hopes were justified.

Just what I neededRalphVery handy, cost-effective way to expand my book storage in a limited space.
FunctionalRosinaThese are useful, but it would be better to have the top screws be with flush heads to avoid clearance issues when using and extension unit.
Extension issueTimothyNice that it adds height, but does not sit well on top the bookcase. Could benefit from more pins to better align with the main unit
OddMariaI'm not sure if I will add this to the Billy shelving or return. Does't seem too useful.
Great addition.DoryNice quality and was easy to assemble. The only complaint is that you have to carefully mark the top of the existing bookshelf to put the anchors in place. You need to then drill pilot holes for the anchors to screw into. If your measurements are off, your shelf extension won't line up properly. If the billy bookshelves had pre-drilled holes, that would make attaching things a whole lot easier.
