Presidents’ Day is one of the best mattress sales weekends of the year, giving even Black Friday some competition. Even though it has come and gone for this year, sales are still running for select mattresses—like one of our favorite cooling mattresses, the Purple Restore Cool Touch. Until March 4, use this Mattress Firm promo code to save up to $500 off this mattress, and also get a $300 “Instant Gift” credit towards an adjustable base. Tempur-Pedic is also running a Mattress Firm sale of its own. Any purchase of a Tempur-Pedic mattress above $3,299 gets 0% interest for 72 months (72 equal monthly payments required). This special is running until March 4.
