Our story: from cardboard festival tents to beds, lamps and business solutions.


We make absolutely everything from cardboard: whether you live, work or play!
As true cardboard creatives, we offer smart, innovative, and creative cardboard solutions because we believe that cardboard is functional, original, surprising, innovative, and an environmentally friendly choice.
How it started
In 2015, the founders noticed how many tents were discarded at campsites after festivals (a staggering 25%) and decided to do something about it. With the expertise and passion for cardboard from Delft University of Technology, the Kartent was born: a fully recyclable cardboard tent, strong enough to withstand rain and large enough for two people. Due to the success of this tent, the Kartent Junior was also created. These tents have been a resounding success worldwide, including at Madnes (NL), Welcome to the Village (NL), Best Kept Secret (NL), Helfest (FR), Unify (AUS), and more. To further improve the reuse of the cardboard after festivals, a cutting machine was purchased that could cut the cardboard into all sorts of shapes.
From tents to beds, lamps and toys
The 2020 pandemic gave us the unique opportunity to unleash our creativity even further: using a cutting machine, we created new products like a chair, a table, and a waste bin made from used cardboard. And it didn't stop there: we switched from used cardboard to recycled cardboard, and many more new products were born, including a cardboard bed, lighting, play walls, and much more.

Why cardboard?
Did you know that cardboard is not only strong and affordable, but also sustainable? Our high-quality cardboard is made from at least 73% recycled material, supplemented with new FSC-certified wood fibers from responsibly managed forests. This way, you're choosing quality and making an environmentally conscious choice! With over 300 unique products designed, locally produced, and made-to-order only, we don't overproduce—that's what makes us unique. Fast delivery, strong, lightweight, and always 100% recyclable.
We are Kartent and we love cardboard!

Timo is a shrewd multi-talent and enthusiastic polyglot. He once started at the big PWC, but the suit was too tight and cardboard boxes were more his thing. Now he gets to play with cardboard every day!
☕️ The best thing is a (black) coffee that someone else makes for you.

Koen Hobbelink
Product creation
Is heavy metal coming from the warehouse? Do you hear someone screaming in the distance? Are there smoke clouds drifting past the windows? Then it could be that Koen is doing some serious work! Don't be put off by his wild appearance, because Koen has a character as soft as cardboard!
☕️ His coffee taste is like his music taste: Nice and black.

Bo Lambrecht

Bo started as a product design intern, but felt so at home among the cardboard that he never left. He now combines his studies with working in the warehouse, where he is up for any job.
