This utility model relates to the field of modular sofa technology, and discloses a modular sofa that can be used for both sitting and sleeping, which can be freely combined. It includes a sofa base, with a fixed plate slidably connected between the two sides of the inner wall of the sofa base. Four telescopic rods and two hollow sleeves are fixedly connected to the top of the fixed plate. An extension plate is fixedly connected to the top of the four telescopic rods, and a drive frame is fixedly connected to one side of the two hollow sleeves. A drive assembly is provided on the inner wall of the drive frame. This utility model, through the combined use of the telescopic rods, hollow sleeves, extension plate, and drive assembly, enables expansion via the extension plate and worm gear mechanism. Users can easily pull out the extension plate and use the worm gear to drive the lead screw to raise and lower, keeping the extension plate aligned with the plane of the sofa base. This effectively increases the length of the sofa, providing more resting space, and is especially suitable for users who need a larger resting area.
