KeyBanc analyst Bradley Thomas came across an "interesting datapoint that is negative" for Tempur Sealy (TPX) during his recent mattress industry channel checks. A smaller retailer, with less than 50 stores, is in the process of changing its floor to Serta Simmons Bedding from Tempur, Thomas tells investors in a research note. Despite being pleased with Tempur's product and productivity, the retailer said Serta-Simmons was offering substantially better terms, Thomas writes. He believes this development, which follows Conn's (CONN) similar decision in Q4, highlights the "continued competitive challenges" in the mattress sector. Thomas has a Sector Weight rating on Tempur Sealy. The stock in afternoon trading is down 35c to $44.19.
