Mattress maker Tempur Sealy International (TPX) is under pressure from activist investor H Partners Management LLC, which has asked the company's shareholders to vote against three of its directors and also has hopes for a new CEO. According to The Deal's Senior Writer Richard Collings, the best way to facilitate a turnaround might actually be to break up the Tempur-Pedic business, which makes high-end foam mattresses, and the Sealy operation, which makes lower margin box spring mattresses. The two businesses combined in a merger that closed in 2013, but hasn't delivered the hoped-for Ebitda boost. The Deal's Senior Reporter Lisa Allen has the details from New York.
