Modular sofa bed and coffee table with storage

Abstract

A modular furniture system divides the sofa into modules that can be combined with a modular coffee table at will to achieve the desired furniture configuration. The sofa modules have foldable armrests and there are storage spaces under both the sofa modules and the modular coffee table. The modules can be put together using connectors to make a sofa bed. The modular coffee table can also be taken out separately to form a double sofa and coffee table, or the coffee table can be expanded to become an ottoman. Each of the sofa modules can be taken out separately and used as an armchair.
