Do mattresses block sound

Mattresses can help absorb some sound, but they are not particularly effective at blocking noise. The materials used in mattresses, like foam and fibers, can dampen vibrations and reduce echoes, which might lessen sound transmission to some extent. However, they do not provide significant soundproofing, particularly against loud or low-frequency noises. For better sound insulation, additional measures like soundproofing materials or dedicated acoustic panels are recommended.
