Sears is currently holding price cuts to as much as 50% on mattresses with brands that include reliable names like Leggett & Platt, Sealy, Sealy Posturepedic and Serta.

But before you buy, make sure to check the fineprint, which includes the following clauses:

1) 50% off select Mattresses. Plus an Extra 10% off thru 12/12/09. Excludes Sealy Union LTD, Sealy Alford, Serta Oak Park, Serta Greenville, Great Price items, Strobel Mattresses, Wolf Mattresses, Natures Sleep Mattresses, Memory Foam Kidz Mattresses, closeouts, Kmart.com and crib mattresses.

2) Our 30-day Comfort Guarantee allows you to try out your new mattress and see how it feels in your home. If you’re not satisfied with your new mattress, contact Sears to receive a one-time credit (minus delivery charges) toward a new mattress of equal or greater value. Exchange of original mattress and new mattress selection must be made within 30 days of original purchase date. Original mattress must be undamaged, unsoiled and free of stains. Delivery fees will not be refunded. A new delivery fee will be charged and a 15% restocking fee will apply. Delivery fees vary.
