Reviews

VERY NICE!JillI purchased this in dark brown and absolutely love it. It was easy to assemble, and is very sturdy. I’m already thinking about buying another set to complete my entire wall.5
Woah BillyShawnI'm impressed. I was going to build bookcases but was impressed with a closet system we installed so when two of the units fit exactly on the wall i wanted a bookcase on, i thought why not give it a try. Saved me money and time. As an engineer i was really impressed with the packaging, installation and quality. Cool beans. 5
Easy to set upJerryThe directions for this are very straightforward. The shelves are very sturdy and work well with each other.5
Perfect!ElizabethGreat color, easy to put together. I did it by myself without any problem.5
Great product.MichaelGreat product, easy install and very sturdy. Looks just like a built in professional book shelf.5
Easy assembly JessicaWe only had ours for about a week (we lost everything due to Helene floods) so I can’t comment on the longevity of the piece. But they were very easy to assemble by ourselves and they were very nice looking. I just wish they came with a way to cover the holes for the shelves after they are placed 4

An updated storage hero

BILLY bookcase has been a steady customer favorite for more than 40 years – but old faithful favorites also need to be updated to keep up with the times. We took a closer look at BILLY and came up with some ideas. One of them means more efficient use of materials, and another makes the bookcase easier to assemble and take apart.

“BILLY was introduced in 1979 and has helped millions of people to organize books and other things in the home. But the world has changed a lot since then, and even popular big-sellers need to adapt to new demands and ways of living,” says Umut Ates, one of our co-workers.

Paper means smarter use of raw materials

Instead of a thin layer of wood veneer, BILLY now has a hard surface of durable paper foil. ”The foil has different printed patterns that look like natural wood and means that less wood is needed to make each BILLY,” says Umut. Using materials only where they are needed is resource-efficient. “And it has meant another positive thing – an even more affordable BILLY.”

Easier to assemble and take apart

BILLY fits just as well in the living room as in other areas of the home – the office, dining room or library. It’s easy to expand and combine with other furniture. But one thing that has had potential for improvement is how the bookcase is assembled and taken apart. “Previously, you had to use about 50 small nails to get the back panel in place, but that’s history now. Instead, you snap on the back panel without any tools,” explains Umut. It also makes it easier to disassemble BILLY without damaging it if you move or want to resell your bookcase. “The improvements have made BILLY more adaptable – it can keep up changing life situations – and it wouldn’t surprise me if this storage hero is as popular in 40 years as it is today.”
