Serta maintains its position as the nation's No. 1 bedding producer and has increased its lead over No. 2 Sealy to $316 million, according to Furniture/Today's ranking of the Top 15 U.S. Bedding Producers.

But the fastest-growing bedding major last year was No. 3 Simmons, which boosted its bedding revenues by 16.5% and finished the year just $8 million behind Sealy.

Furniture/Today uses public and private information to develop the wholesale shipment figures in its report of the Top 15 U.S. Bedding Producers. We begin the process by sending a survey to some two dozen bedding producers, asking them to supply audited and accountant-verified figures for their 2013 bedding shipments.
