AwesomeDuy M.Awesome product, waited a long time to get it.5
Easy to install.Caryn B.The Billy bookcase extension was easy to install, especially after watching a Youtube video.5
Almost perfectRISA H.It’s perfect except it only attaches in two small spots and lifting it with that piece barely secure is hard.4
Works well, but wish compatability was clearerHerbert M.Bought 2 of these to use with shorter Billy bookcases - which did not have the pre-drilled holes on top. While the intended models to use it with are mentioned in the detailed description, this really needs to be called out prominently on the main page.3
Great productBarbara E.We put two of these together with extension pieces on top to just about reach the ceiling. With a wood strip from Home Depot where the two pieces meet, they look like one piece. We were going to do the crown molding on top, but decided to keep it simple for now. Can always add that later. Went together quickly and easily. My guy did it without help. Of course this it attached to the wall. They are also screwed together for more security since we have the wood down the center and might have wood molding later. I considered getting plastic plugs for the shelf holes but read that someone had success with spackling compound. If the spackling doesn’t work long term, it is easily removed and can be replaced with the plastic pieces then. Quality is excellent. Paint surface is extremely strong. Units are sturdy. We are completely happy with this purchase.5
Changed hardware to cheaper qualityJorgeI’ve gotten this product before, but this time IKEA has changed the hardware to cheap plastic so they do break easily. I had to come up with an other way of putting it together.2
Bookshelf extendersPeggyThese shelf extenders allowed us to customize our Billy bookshelves. They were easy to assemble, gave extra height to our bookshelves, and look seamless.5
My experience with BillyJACQUII purchased 2 bookcases and 2 extensions for floor to ceiling look. I'm 77 years old and assembled all of the units myself, thanks to the very easy to follow instructions. Now my son-in-law will come and secure them to the wall.5
These extensions are greatEthanMy ideal library would have wall-to-wall books. These extensions are an easy way for me to take my existing Billy bookcases and move them towards that goal. They are easy to put together and install. Their quality is the same high quality as the bookcases themselves.5
This product works perfectly exceptABBYThis product works perfectly except the billy bookcase I was attaching this to did not have the predrilled holes and took extra measuring and drilling to get the pieces to work together4
PantryKathyWorked perfectly for what it was bough for5
Looks great for high ceiling roomsMichaelThe Billy bookcases with the extension look really great in our room with 9-foot ceilings. They go together easily and the extension seems sturdy.4
Just what I wantedTamiThis is a very heavy piece. Worked just like I wanted.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 veneer?

A veneer is a thin wooden sheet attached to things like particleboard 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.
