Sofa Matress
Size and Shape:Sofa mattresses are often thinner and narrower than standard mattresses to accommodate the space constraints of a sofa bed. Common sizes include twin, full, or queen, depending on the size of the sofa bed.
Materials: Many sofa mattresses are designed to be flexible or foldable so that they can easily fit into the sofa when it is folded into a seating position. This flexibility allows the mattress to be stored compactly without taking up much space.
