A furniture system with a reclining assembly including a modular furniture assembly and a reclining assembly. A passageway in the reclining assembly allows coupling to a slit in the modular furniture assembly with a coupler. The reclining assembly includes a housing and a footrest assembly that moves with respect to the housing. An additional base can be coupled to the front end of the footrest assembly, with one or more (e.g., two) sled rails mounted on an underside of the additional base, such that the additional base slides on the sled rails as the footrest assembly moves from the compressed non-reclined position to the extended position.
