If you are in need of a discount code to use for your purchase then you can use my referral code. Sleep Number gave me this code when we bought our beds to pass on to friends and family to get them the greatest discount on their purchase. You cannot stack coupons with current promotions but does work along side their promotions to get you the greatest discount possible on your whole purchase. You may need to chat or call them to complete your purchase if your coupon code does not work online. They can enter it manually to get you the discount. So if they are having a sale and the top mattress is 30% off and many times the base is not in sale, then this coupon will get you a discount on the base and sheets.
