You could have attributes called table and chair, each referring to a
furniture. Upon saving, have a validation check that table is a table
and chair is a chair. I'd recommend doing this with a furniture_type
method, rather than directly checking the range; if you somehow manage
to be able to change this ID silliness, you can then have the method
check something else instead (such as a enumerated type attribute).
