A sleeper sofa mattress frame comprising:
- a foldable mattress frame comprising a left rail, a right rail, a bottom rail, a head frame portion, a torso frame portion, and a foot frame portion;
- a first solid support deck located at the torso frame portion and coupled to the left rail and the right rail, the first solid support deck comprising a first solid support deck mattress facing side and a first solid support deck underside;
- and
- a first support rail coupled to the first solid support deck underside at first support rail ends, the first support rail comprising the first support rail ends and a first support rail middle segment disposed between the first support rail ends,
- wherein the first support rail is affixed to hold the first solid support deck in a bowed position against a bias force of the first solid support deck, wherein, in the bowed position, a gap is formed between the first support rail middle segment and the first solid support deck underside;
- wherein, under a weight of a mattress, the first solid support deck is configured to move into a flattened position such that a portion of the first support rail middle segment closes the gap and contacts the first solid support deck underside;
- wherein the first solid support deck is bowed to inhibit hammocking or sagging of the mattress.
