Both USO and Workshop Rearranged create completely new WorkshopMenu0XXXXX FormID lists and workshopRecipe_XXXX FormID lists which replace all of the vanilla and DLC lists.
This means that any mod which directly adds their items to, or references, the vanilla or DLC versions of these FormID lists wouldn't be able to add its items because it is either (a) referencing a FormID list that no longer exists or (b) adding to a FormID list that looks nothing like it did originally and likely has a different number of sub-FormIDs attached.
Hence everything that doesn't use script injection to dynamically add items to these FormIDs and instead adds them using hard-coded overwrites in the .esm/.esp/.esl file requires a compatibility patch if you use Workshop Rearranged. For example, the DLCs and Creation Club mods use the overwrite method, and that's why Workshop Rearranged requires all DLC files to be installed, since it also directlyoverwrites all of those FormID lists.
Since you're on XBox, you'll need to wait until the authors of these two mods create versions that are compatible with Sofa King furniture (assuming they are being added to the vanilla menu's FormID lists), or for someone to create a patch to resolve the conflict.
