Saved views are the key.
Make two layer sets, 1st with dimensions, 2nd with furniture. Save a view from each layer set then they are set as visible on your plan view.
First view "dimensions View"
Second View "furniture view"
Then make your layout dragging 1st and 2nd view to that same layout. Saved views will now keep their layer settings.
Same applies to other settings/atributes too, like pen sets etc. Views have to be used to save different settings from your model.
