Klippan is a model of sofa manufactured and sold by IKEA. IKEA's nomenclature conventions name upholstered furniture after places in Sweden. The Klippan sofa is named after Klippan Municipality in Southern Sweden. Klippan was developed by IKEA's product developer and head of design Lars Engman and designer Noboru Nakamura. It was launched in 1980 and continues to be one of IKEA's most popular and longstanding products. It comes in a standard two-seat size and can be fitted with a range of removable and interchangeable fabric covers. As well as standard cotton covers, IKEA sells 'exclusive' collections of covers, retiring designs after a year.
