Shares of both Tempur Sealy (TPX) and Select Comfort (SCSS) are higher after Dealreporter discussed the potential for a transaction, KeyBanc analyst Bradley Thomas tells investors in an intraday research note. Such a deal would have areas for value creation, but seems "more complementary and adjacent," the analyst writes. Further, he does not expect Tempur products to be sold in Select stores. He also calls the timing not ideal for Tempur, saying the company should be focused on keeping sales in the wake of its split with Mattress Firm. Thomas only sees "modest" synergies should the two companies combine. Shares of Select Comfort are up 10% to $35.33 in late afternoon trading while Tempur is up 4% to $53.06.
