About TÔNN

TÔNN Furniture designs furniture for everyday life. Everyone’s daily lives look different and change over time. That’s why we’ve created the Portal shelving system, which is easy to adapt, rebuild, and divide. We believe that sustainable and personalized interior design is the key to thriving at home.

It all started back in 2011 when our founder, Josefine Halfwordson started casting concrete tables in a basement in Stockholm. A few tables to friends became many and soon the company Betonggruvan (“concrete mine” in Swedish) was born. 

A lot has happened since. Tables have been replaced by shelves and the name Betonggruvan has become TÔNN furniture. Why TÔNN you might wonder? TÔNN is a made up word that (for us) means a new chapter, an open mindset and of course – room for change.

You can buy our furniture here in our webshop with worldwide delivery

The birth of the shelf


The Portal shelf system was born in our first store on Sveavägen in Stockholm. TÔNN was then called Betonggruvan and we made the shelf to be able to show the products that we used to sell. The shelf was easy to assemble, change and rebuild. And it did a good job. So good in fact that more and more customers started asking if the shelf was for sale. After some time drawing, designing and developing, Portal finally became a product! Since then, we have added more combinations, heights, colors and accessories. The shelf is now sold and shipped all over the world and thanks to our customers’ feedback and wishes, we continue to develop it together.


We help you plan your Portal shelf

Adapt the Portal shelf to your home. Fill in desired width, height and color in our Portal planner. We’ll get back to you with a sketch and price.

When you are satisfied, we’ll send you a shopping cart with all parts for your shelf ready to be ordered. The service is free of charge, of course!

Life in @_fridalund's Portal.
Every good story needs an ending to make room for exciting new chapters. Such is the tale of our pinewood shelves. We bid them farewell last autumn, but a handful of the small 45 cm are still in stock.

Chin up, pinewood seekers! Head over to TÔNN 4-ever on Facebook, where you can buy, sell, and inquire TÔNN furniture. Hope you’ll find some pinewood treasures there.
