Twenty-three-year-old Louisville native and University of Kentucky graduate Kim Brown Knopf opened her first mattress store, Mattress Warehouse, in South Charleston, W.Va. in 1983. Nearly 20 years later, when she wanted to expand her company into her native Kentucky, the Mattress Warehouse name was owned by another company in that state. So, the Kentucky mattress stores opened under a new name, Sleep Outfitters.
Today, her company, Innovative Mattress Solutions (iMS), employs more than 500 people and operates more than 160 stores in seven states (Ohio, West Virginia, Kentucky, Indiana, Tennessee, Virginia and Alabama) under the Mattress Warehouse, Sleep Outfitters and Mattress King names, and features America’s most iconic bedding brands – Sealy, Tempur-Pedic and Stearns & Foster.
