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 additionJolizGreat addition5
Pleased purchaserLindaAdding the extension to our Billy bookcases brings them up to almost ceiling height -- really makes them look built in.5
Poor PackagingKRISTENIt was if IKEA didn’t value Billy. We believed the great product with a great price was what we would be getting again. We we wrong. Really wrong. You could have cared less about Billy. It was wrapped with poor quality tape and was missing the instructions as well as the back. What the heck. Never again. We cared more about Billy than you.1
Awesome!MargaretLooks great! Helped me make built-in shelves in my bathroom. Wish they were a little cheaper though5
Pretty Nice!Juan G.I love the way it looks, is just a little bit pricey.5
Book shelvesJANETWaited a long time for stock to come in but once receiving it was exciting to get these beautiful affordable shelves put up..lots of extra hardware but missing 1 shelf screw which was not fun..we are enjoying the shelves5
Excellent product excellent priceJimExcellent product excellent price5
I love my glass doorPETRAI love my glass door book and bar shelfs5
So soClaudiaThe way it attaches to the main bookcase makes seem unstable, but since so high up I don’t worry too much about it.5
Great addition to the Billy BookcaseRogiVeraI started with a couple of Billy bookshelves and then decided to make an entire library. I added the top units to make it look like an entire wall of bookshelves and when it was all done it look like a custom job. Great product with limitless options4
Wish it worked with all height Billy bookshelvesAllysonFrustrated that this only works for the 79” height bookshelf.2
Matches bookcaseGlennMTypical good IKEA quality - but not set up to attach to Billy bookcase (no holes etc.)5
Kellys88If you are really perfectionist consider that this part looks a bit different from the Billy bookcase3
Love my Billy bookshelvesUser413This makes the height perfect for my room.5
Easily attaches to base unitAllThumbsJust the right height for the room4
Defective productGHPTThese don't actually attach to the Billy bookcase. The instructions claim that there are holes on top of the bookcase to attach this to, but there are no such holes. After more than an hour on the phone with customer service, the rep acknowledged that there's no way to attach the extension.1
Fits perfectly!CindyHThe Billy height extension units perfectly fit Billy bookcases to allow me to store more of my favorite things. They are easy to put together and appear fairly seamless once in place.5

Our take on wood

Wood is the material most commonly associated with IKEA furniture, and for good reasons. It’s renewable, recyclable, durable, ages beautifully and it is an important part of our Scandinavian design heritage. At IKEA, we believe that sourced in responsible way, wood is a key change driver for climate mitigation. In 2012, we set a goal that by 2020 our wood would be from more sustainable sources. We are happy to announce that we have reached this goal and today, more than 98% of the wood used for IKEA products is either FSC-certified or recycled.

Forests are critical for life on earth

Forests contribute to maintaining balance in the atmosphere, purify the air that we breathe and are part of the water cycle. They nourish wildlife biodiversity and provide homes for indigenous communities who depend on forests for their livelihoods. 90% of plant and animal species living on the planet need forests to survive. They provide sources of food, fuel, timber and many other ecosystem services that we rely upon. Sourcing approximately 19 million m3 of roundwood per year from some 50 countries, IKEA has a significant impact on the world’s forests and the timber industry and a huge responsibility to positively influence how wood is sourced. Responsible wood sourcing and forest management ensure that the needs of people dependent on forests are met, that businesses can work sustainably, that forest ecosystems are protected and biodiversity is enhanced.

100% wood from more sustainable sources

At IKEA, we work with strict industry standards to promote responsible forestry. We don’t allow any wood in our supply chain from forest areas that are illegal or contain high conservation values or from forest areas with social conflict. Before starting to work with IKEA, suppliers must demonstrate that they meet IKEA critical requirements on wood sourcing. IKEA requires all suppliers to source wood from more sustainable sources (FSC-certified or recycled wood). All suppliers are audited regularly and non-compliant suppliers are required to implement immediate corrective actions. By working together with our suppliers, we are proud to announce that we have reached our more sustainable sources goal, which we set out to achieve by 2020. Today more than 98% of the wood used for IKEA products is either FSC-certified or recycled.

IKEA Forest Positive Agenda for 2030

As pressure on the world’s forests and the surrounding eco-systems increases due to unsustainable agriculture, the expansion of infrastructure and illegal logging, it is time to take an even more holistic approach to protect and support these important resources for generations to come. The IKEA Forest Positive Agenda for 2030 set out to improve forest management, enhance biodiversity, mitigate climate change and support the rights and needs of people who depend on forests across the whole supply chain and drive innovation to use wood in even smarter ways. The agenda focuses on three key areas: • Making responsible forest management the norm across the world. • Halting deforestation and reforesting degraded landscapes. • Driving innovation to use wood in smarter ways by designing all products from the very beginning to be reused, refurbished, remanufactured, and eventually recycled.

We accomplish more by working together

For many years, IKEA has partnered with businesses, governments, social groups and non-governmental organisations to fight forest degradation and deforestation and increase the volume and availability of wood from responsibly managed forests both for our own supply chain and beyond. We are on a journey to improve global forest management and make responsible wood sourcing the industry standard, contributing to building resilient forest landscapes and improve biodiversity.

What is particleboard?

Particleboard is made from recycled wood and sawmill waste – so wood pieces with the wrong shade, woodchips and sawdust become a valuable resource instead of being discarded. We use boards for things like bookcases, bed frames, sofas and kitchen frames. To protect from wear and moisture, we apply varnish, veneer or foil that adds to the furniture's look. The day your sofa or bed needs replacing, the material in the particleboard can be recycled into something entirely new.
