There is something unknown and invisible influence on furniture design works. Nobody realizes that something of image-binding in KEVI double wheel covered the housing and the shifted stem.
Always a new car requires a new wheel-design. A wheel design makes an impact on modeling image of the upper-part.
But now, Rasmussen’s design has achieved an international standard.
Masterpiece will stay alive as a design principle in the future.

Simple design and good quality parts ensure an upper-part for a longer life. Eco-conscious and repairable fittings are desirable for furnishing market needs.
Reproducing the disassemble mechanism and replacement are important before waste disposal. And repairing parts should be supplied for user to save resource.

KEVI original castors (1965 -1971) stocked for distribution in 50yrs

My stock for a half-century would be useful for the next generation.
Some possible suggestions are as below:
– For restoring of early KEVI chairs
– Good educational materials for industrial design to teach molding and assembly structure simplified
– Understanding PAT management and design registration to know how to prevent the occurrence of copied products

– Important for design art museums, designers and students as Danish modern design collection of KEVI original products
– Comparative display of imitation and timeless designs as the history of world design registration and strange standardization

Above all, it is the best for the archive of Fritz Hansen A/S and Design Art Museum collection.

* Notice: : ABE collection

Early KEVI’s typical model set or all stocks are available for sales.

The condition of the stock is

– Early products: almost fine with little rust from shipping from Copenhagen

– Package: uncovered because of long store in warehouse since imported in 1972
