Composed of just three different elements, the Jam bookcase is a cleverly and elegantly executed design. The defining element is a wedge, which allows the bookcase to be assembled without the use of screws or tools. The shelves are quite simply jammed onto the wedges and then gravity and friction take care of the rest.

"We always find ourselves captivated by the simple things that surround us – simple things that fascinate us because they only need a minimum number of elements in order to become very functional final objects. The humble wedge is a great example of such a thing. Due solely to inclining surfaces set against each other in friction, a wedge is able to support something as weighty and considerable as a door. It was this observation that led us to design a flatpack bookcase that can be assembled without the need for any tools or screws." – Rudolph Schelling Webermann

The Jam bookcase is available in various sizes and can be placed against a wall or used as a room divider. The shelves' softly rounded corners give the unit an inviting and friendly visual expression. With its versatile design, the bookcase works just as well in small apartments as it does in large offices, where its purity and materiality craft a calming and pleasant presence.

Rudolph Schelling Webermann consist of Carsten Schelling, Ralf Webermann and Sven Rudolf who met during their studies at FH Hanover University of Applied Sciences and Arts. After working for different studios, the three designers decided to start their own design studio. Rudolph Schelling Webermann is specialized in consumer product design.

"We are driven by the romantic idea that a designer is an inventor of products that is able to create a better world. We love to challenge materials, products and people's behavior. The way to our designs lies in the search for a new, better, different, unjustly forgotten or humorous idea."
