Over 60 million BILLY bookcases have been sold around the world. Why? Because it just works. It’s practical, it’s sleek, and it blends with almost any style — modern, boho, minimalist, Scandinavian, farmhouse, you name it.

🛠️ Easy Assembly and IKEA Quality
Yes, you assemble BILLY yourself — but that’s part of its charm. IKEA designs its furniture for easy DIY setup. All you need is a screwdriver, a hammer, and a bit of patience.

Secure the back panel properly for stability.

Use the wall anchor (included) — especially if you have children or pets.

If you’re stacking or combining multiple BILLYs, use the joining hardware IKEA provides.
