1800Mattress.com (formerly known as 1-800-Mattress, Dial-A-Mattress and Dial-A-Mattress Operating Corps) was an American bedding retailer headquartered in Hicksville, New York and famous for its ads that used the slogan "leave off the last S for savings" (since the word "mattress" has 8 letters and only 7 are necessary for the phoneword).
