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.5
Stepped UpAllanWhat a clever idea to get your bookcase in the correct proportion to your ceilings. And extra space to boot.5
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.4
I'm very pleased with the purchase.MaximMy hopes were justified.5
GoodNicholeItem as described5
Not really worth the added expenseSheriI ordered these to top the primary bookcases to gain additional height/storage. However, considering the size, the value is not proportional4
Just what I neededRalphVery handy, cost-effective way to expand my book storage in a limited space.5
FunctionalRosina O.These 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.4
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 unit3
OddMaria S.I'm not sure if I will add this to the Billy shelving or return. Does't seem too useful.2
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.4
Happy I could gain onePauletteHappy I could gain one more storage area!5
It suited my space verySheelaIt suited my space very spot on. I love how you cam easily customize it.5
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.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 leftovers – so wood pieces with the wrong shade, woodchips and sawdust become a resource instead of possibly 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.
