Whether have one in your house or all your friends have it in theirs, IKEA‘s super basic Lack coffee table is kind of a home decor must-have among 20-somethings. And though it only set you back about $10, it probably managed serve as a makeshift mini ladder a time or two. If you’ve ever wondered just how it manages to be so durable, National Geographic has an answer for you. The publication recently released a video showing exactly how the table is made and it’s weirdly mesmerizing.

Unlike the heavy side tables you probably find at your local flea market, a key feature of the Lack table is how lightweight it is. Turns out that’s because it’s 90 percent cardboard. Sure the frame is made from wood, but inside you’ll find raw paper filler that’s been magically transformed into a honeycomb shape. IKEA calls this structure the “board on frame” technique.

In the video one of the men who works in the factory tells the camera he weighs 100 kilos (220 pounds). He then stands on a layer of the honeycomb and it doesn’t even crumble a little bit. The filler is layered inside the table to create an ultra durable design that can also stand up to even to most destructive of college students. IKEA, we love you and we’re forever grateful.
