What sofa beds are best for nightly use in larger rooms?
A foam mattress can be used on a futon frame if it is flexible enough to bend with the frame.
Many standard foam mattresses are too thick or rigid to fold easily, which can make it difficult for the futon frame to switch between sofa and bed positions.
Mattresses made specifically for futons are typically thinner and more flexible, making them better suited for the folding mechanism. Additionally, a futon frame with closely spaced slats provides better support for a foam mattress, helping to prevent sagging.
