1980 Due to the oil crisis, Sika Møbler is in a major crisis and threatened with closure. The import of raw materials and furniture from Malaysia takes place in USD, which in one year rises from DKK 4.75 to DKK 12.50. The product sale only took place in DKK which was also devalued 2–3 times a year. The result is that both turnover and staff are reduced by over 50%, and Ankjær's second son, Knud, joins the company.
1983 Knud Andreasen buys the company. In the mid-1980s, there is a boom in conservatory construction, and the demand for wicker furniture in rattan explodes.
1986 Sika Møbler has made exclusive agreements with dealers all over Denmark, and therefore Knud establishes the sister company Cane-Line to meet the great demand for rattan furniture.
1988: Ban on export of raw rattan
Indonesia, Malaysia, and the Philippines, who produce all the world's rattan, makes it illegal to export rattan as a raw material. Sika Møbler's Danish production is therefore forced to close.
