[Elfsea] Futon question

[Floyd Brigdon]

    Greetings,

    After another travesty with the air mattress this weekend, Angelique and
I are looking into building/buying a portable camp bed and are trying to
find somewhere to puchase a king sized futon for said bed.
    The problem is that they seem to be almost non-existant....
    Would any of you good gentles have any idea about where to find a king
sized futon? Or what other options do you all use?

    Thanks in advance.

    YIS,

    Milo
