Can a foam mattress be used on a futon frame?
A foam mattress, such as those from Koala, Sleeping Duck, or Eva, can be used on a futon frame if the frame provides adequate slat support and remains flat.
Foam mattresses are generally compatible with futon frames as long as the frame remains flat and provides sufficient support, such as closely spaced slats to prevent sagging.
For instance, modern furniture brands like Koala, Sleeping Duck, and Eva design their foam mattresses to work well on supportive flat surfaces with appropriate slat spacing.
However, foam mattresses tend to be less flexible than traditional futon mattresses, so they may not suit futon frames that fold or bend into a sofa position.
