The covers went on sale for $104 each last month at the high-end NK department store, drawing ire from a Stockholm homeless charity, the Aftonbladet newspaper reported.
Advocate Yvonne Borg said she couldn't see how sleeping under what appears to be cardboard would be "particularly pleasant" and said she saw the marketing as exploiting homeless people.
The bedding was designed by Dutch company Snurk, which says it donates a small portion of profits to homeless groups, the newspaper said.
Department store spokesman Jorgen Eriksson told the paper exploitation "is not the purpose" of the marketing.
"One buys it to show awareness," he said.
The duvet covers have been selling quickly and the department store said it was nearly out of stock, the report said.
