Hi yellowgrly22,
The Brooklyn Bedding site only carries one mattress because it is designed to compete with the other “simplified choice” online mattresses that are listed in post #2 in this topic which all have only a single mattress.
Dreamfoam is their online channel that carries a much wider range of mattresses and R&S Mattress are their local stores. Each of these sales channels is targeted towards different groups of consumers and all of them are made at the same Brooklyn Bedding factory (except some of the mattresses at R&S Bedding which are made by different manufacturers).
