Mattress retailer Innovative Mattress Solutions has purchased Mattress King of Alabama, according to iMS CEO Kim Knopf.

The 19-store Mattress King deal, gives iMS 150 stores in six states. Headquartered in Winfield, W.Va., iMS operates as Mattress Warehouse, Sleep Outfitters and Mattresses Unlimited in West Virginia, Ohio, Kentucky, Indiana, Tennessee, and now Alabama.

Mattress King is based in Huntsville, Ala., and also operates stores in the Birmingham and Tuscaloosa markets. Owners Wayne and Kay Koswoski opened their first Mattress King in Huntsville in April 1989. The company grew to 19 stores despite losing two stores to tornadoes that swept through the state on April 26, 2011.
