Hi JFKinDC,
Yes there would be many. Almost any mattress that was made completely from foam (either memory foam, polyfoam, or latex foam) and many pocket coil mattresses can be shipped compressed and rolled. Most online manufacturers do this so that their mattresses can be shipped by courier instead of truck freight which is much less costly.
All of these are also flexible and would bend around corners without any difficulty even when they are fully expanded.
Just in case you haven’t seen it yet … the better options or possibilities I’m aware of in the Washington, DC area are listed in post #2 here and the tutorial post includes several links to many of the better online options I’m aware of and include many “foam” mattresses that ship compressed.
