Tempur Sealy International Inc. escalated a legal battle with former customer Mattress Firm Inc., filing a lawsuit accusing the retail chain of selling copycat products without authorization, the Wall Street Journal reported. The complaint, filed on Tuesday in a Tampa, Fla., federal court, accused Mattress Firm of selling mattress and bedding products in the Tampa area that are “strikingly similar” in their appearance and their advertisements to Tempur Sealy’s trademarked Tempur-Pedic brand. Richard Anderson, the president of Tempur Sealy’s North American operations, said in a sworn declaration that Mattress Firm appeared to be testing a confusingly similar Therapedic brand in the Tampa market and online for the critical Labor Day sales weekend.
