There are some things that should not be purchased on the internet. Mattresses are one of them. I did not do enough research and found this out too late. People and sites talk about equivalents and the same mattress being sold under many different names by different retailers. Most of the internet sites sell a cheap or dated version of the mattress sold in stores, and the savings if any are inconsequential, especially if you are unhappy with the product when it arrives, because it is not returnable. The 2010 Stearns and Foster mattress has intelicoils which are a spring within a spring and a queen size should have 800-850 springs. The mattresses sold on the internet have 600 single coil springs. They are nothing like the mattresses sold in stores. I place most of the blame on Stearns and Foster as they are the ones who put their name and reputation on the line by manufacturing two grades of mattresses and using dozens of names. They are doing a disservice to their customers. The only way you can be sure you are going to get a mattress you are happy with is to lay on one in a store and order the mattress from that store. I would never order another mattress off the internet. My next purchase will be from a local store. Mattress Firm has current models for the same price as the internet, and you can try them out before buying. Most department stores have sales a couple times a year where the prices are the same as on the internet for a much better product. Also here is another place to do your research.
