Not at all like what's in the store

Horrible experience - the mattress felt pretty soft (it is a firm mattress, but I like a little plush) in the store, but when it arrived at home, it's hard as a rock. Manufacturing defect? Sears was NOT good about returning it, nor was Sealy. Apparently, their warranty doesn't cover if it's too HARD, only if it's too soft, so no returning it for free - 15% plus $70 to return it, with or without a replacement/change. This mistake just cost me a lot of back pain as well as $200+. Not happy with either Sears or Sealy. Never again for either of them.
