Buyer beware. They will sell you a mattress with a ten year warranty, but when something goes wrong Mattress Firm will say it's within normal limits. They will have you take photos and upload them to their website and use those to make their warranty decision. Of course, if you would like to have an inspection you can pay $39.95. Better yet they will send you a 20% off coupon so you can buy a new one. I just spent nearly $3000 less than two years ago. I shouldn't have to buy a new one yet because the old one is lumpy.
