It should be noted that the futon mattress will extend slightly above the back deck and forward of the seat deck. Depending on it's thickness, the extensions will be about 4" at the back and about 1" at the seat.
It should also be noted that because of it's extra height, the queen size may not be used as a true wall-hugger.
If you have special space restrictions, we will be happy to accommodate you by making up a frame size to meet your needs. This is usually accomplished by narrowing the armrests, but can even include a slight shortening of the decks.
Of course a small surcharge would apply.
