IKEA is a large multinational retailer of furniture and home furnishings established in Sweden in 1943. It has grown to over 500 stores worldwide. In the past, IKEA faced issues with formaldehyde in some products in the 1980s and child labor violations by some suppliers in the 1990s. To address such issues, IKEA took actions like stopping problematic product sales, working with organizations like UNICEF and ILO, and monitoring suppliers more closely. IKEA also focuses on sustainability and uses mainly renewable and recyclable materials in its products.
