Very deceptive store warranty experience

I went shopping at this store because I needed a mattress in a hurry and they are local. The first mattress I bought hurt my back so bad that I returned it within 3 days. The second mattress I bought began giving me back problems after 3 months. The whole middle of the mattress sank down and springs started making themselves well known. It really hurt. I called the store because they told me I had a 10 year warranty but they never provided the details. Not even on the receipt. I was pointed to their website and informed I was required to pay someone $25 to inspect the mattress and then had to pay $69 for another delivery should the inspection prove the mattress was defective. To me, this is no warranty at all. It says that I have to pay extra for the warranty to take effect. I don't know about the rest of you but when a product is rated with a 10 year warranty and is clearly defective after 3 months the consumer should not have to pay to replace it. I will never do business with this company again. I might even drop the mattress off at their front door so that they have to dispose of it.
