Collapsible


Wintersport and skiing are almost synonymus. Tobogganing, is a type of winter sport, albeit not as popular as skiing but extremely fun and favoured in some regions.

In collaboration with Max Kimpel we developed and realised a polyethylen based, space-saving sleigh that can be stored flat in the warmer months of the year.
This collapsible sled is a proposal for young families and winter sports enthusiasts who normally use public transport or own smaller cars.

The appearance of the collapsible sleigh is inspired by the traditional shape of the swiss »Davoser« sleigh. The shaping principal for it is simple. A two-dimensional sheet of polyethylene is transformed into a three-dimensional body. The shape and the radial curves on the surface are CNC milled.
Polyethylene provides the necessary flexibility, strength and tension and due to it’s unadulterated property it is easy to recycle.
The skids which are pushed over the edges of the body are made from stainless steel tubes. A statement of durability and trust. Even though its shape has been inspired by a classic design; its appearance, material combinations and belting system are ingenious and inventive.
A unique belting system underneath the sleigh allows for the form to be reversibly fixed into position.
Next to economic advantages its collapsible feature allows users to transport it easily and to save space when it is stored. Its light weight design is favourable for its comfort and leaves the user with more energy for adventures in the snow. The collapsible sleigh summarises as a traditional yet cutting edge product.
