One thing I would do if the mattress you tried at the store is still there is to photo all of the tags and display information and compare the info to the tags on the mattress you received. If the information is not EXACTLY the same then you did not receive the product you paid for and you can claim "bait and switch". There are so many differences that can be made to change the quality, feel and cost of a mattress even down to the thickness of the foam layers and top covers but those differences should be listed on the tags and information.
This^^^^ Compare all that info with your receipt. If it all matches, JCP delivered what you purchased. If that's the case you will likely end up fighting with the manufacture...good luck. Hope it doesn't turn into a pricey lesson. That stuff should always be purchased at a place that offers their own warranty(such as the no questions asked 120 night sleep guarantee)
