Opsvik's furniture can be found under the brand names: Rybo (Garden), Nomi High Chair, Håg (Capisco, H04, H05, Conventio Wing), Varier (Balans), Stokke (Tripp Trapp) Naturellement (Reflex), Cylindra (Furniture objects) and Moment (Globe).
The saddle chair Håg Capisco was launched in the 1980s and inspired by the horseback rider's dynamic posture.
In 2010 this design classic was made accessible for a wider audience when the Capisco Puls was launched.
Peter Opsvik's kneeling chairs were originally manufactured by Stokke (now Varier), Håg and Rybo.
[19] Opsvik has also received Torsten & Wanjas Söderbergs design award[20] in Sweden for his pioneering, movable and variable furniture.
In 2013 Norsk Form (The Foundation for Design and Architecture in Norway) awarded Opsvik Jacob-prisen for 2012.
His Tripp Trapp Chair is held in the collection of the Museum of Modern Art (MoMA) in New York.
