Named after the Slovenian word for one, the design stands on a single, powder-coated steel tube for a leg, which is bookended by either a round or square base and top.
The smaller rod that creates the two hooks skewers the leg, forming a graphic line that runs straight across the middle of the tabletop from below.
Ena's simple metal frame cuts down on any extraneous details, while minimising the amount of material needed in the process.
The table can be adapted in different colours and finishes to match its surroundings and can survive both in indoor and outdoor environments.
Rex Kralj was founded in 2012 to resurrect designs, prototypes and sketches from celebrated Slovenian architect Niko Kralj.
This marks the first time that the brand has collaborated with other designers to go beyond Kralj's existing catalogue of work and imbue a new range of products with his design philosophy.
"My passion for modernism and geometrical elements is what connects me to Niko Kralj," said Harrsen. "Ena's design maintains purity in form, while the hook adds both a practical and unexpected detail."
