Hi Janyee,
The reason you don’t see the names listed below on our site is because Sealy creates different names for different retailers in an effort to make shopping around more difficult. The nice part about the Spring Free line is that while the names do change, there is only one of each comfort (1 pillowtop, 1 plush, etc). The Fairway Dunes is an exact match to our Whistlewood and the Box top is known as the Laurel Cove on our site; both can be used on the adjustable frame. If you have any questions, please give us a call at 1 800 455 1052.
