Copenhague CPH30 Walnut Extendable is a dining table extension designed by Ronan and Erwan Bouroullec for the Danish brand HAY. The table consists of plywood that can be chosen with a linoleum or lacquered walnut top. The base is made of solid walnut and has the same angled legs as the rest of the series but differs thanks to the pull-out design. The central sliding mechanism makes it easy to insert additional leaves. The table, which comes in sizes 200 and 250 cm, can have four leaves. When using more than two additional leaves, you will need to purchase the CPH30 Extendable - Support Leg. The extension panels are always sold separately. Copenhague CPH30 Walnut Extendable is also available in oak.

The Copenhague series includes several tables that Ronan and Erwan Bouroullec designed in 2013 specifically for the University of Copenhagen. The furnitures look is welcoming and homey but made to be durable and easy to care for. These important requirements were set by the university when producing the series. By using a rich design history combined with modern technology, the Bouroullec brothers met the requirements. A broad series with a strong design language.
