Make sure you install mod loader and minecraft forge for the client, make sure you install minecraft forge for the server. Then place the client jammy furniture mod zip file in .minecraft/mods and the server jammy furniture mod zip file in the mods folder in the server. It should work, I tested it myself and it worked perfectly.
It's installed correctly because some of the items are craftable, but others are not. For example, my friend and I can craft the cabinet without the top, but cannot craft the one with the top. Were able to craft the lamp, chair, and table also. But were unable to create either of the sinks (just to give you an example)
Both the cooker and washing machine were craftable, but neither of us were able to open their GUI's. Same with the cabinet
