Exhibit 99.1 FOR IMMEDIATE RELEASE Contact: Tammy Nystuen Select Comfort Corporation (763) 551-7496 tamara.nystuen@selectcomfort.com SELECT COMFORT CORPORATION UPDATES FOURTH QUARTER SALES EXPECTATIONS Minneapolis - (Dec. 3, 2004) - Select Comfort Corporation (NASDAQ: SCSS), the nation's leading bed retailer and creator of the Sleep Number(R) bed, today announced that it expects net sales for the fourth quarter ending January 1, 2005, to be below prior guidance. "Sales during the early part of the holiday season, particularly over the Thanksgiving weekend, were slower than anticipated," said Bill McLaughlin, chairman and chief executive officer. "Based on these results and uncertainty concerning consumer confidence over the holidays, we felt it prudent to update fourth quarter sales expectations." Based on current trends, Select Comfort expects fourth quarter net sales to be $143 to $149 million, which is 12 to 17 percent higher than fourth quarter 2003 net sales on a comparable basis. Previous fourth quarter 2004 guidance was $153 to $158 million. The company will report fourth quarter sales results on January 10, 2005, after market close.
