JC Penney is broke and filed bankruptcy, do you really expect to get anything out of them? Do you really think they really care about customer service when they probably won't be around after the 1st of the year? Might want to get as much back from them as you can, then go to a furniture store and buy your mattress, preferably one that has been around for a while, and will still be around for a while. One with a 120 day no questions asked return policy (often you pay a little extra for hat as well). Pay for delivery and pay with a credit card.

You may stand a fighting chance from Serta, especially if the mattress is not the one you ordered, but probably not. Good luck, your going to need it. Gene
