Do I need all the items in a set?

[Raaxon]

I'm curious as to whether or not I need ALL the items in a series to get the House Points for them. Example: Do I need every piece of Sleek furniture, including wall and floor, to get the points, or can I leave one or two items out?

Yes, for full points, you should include the floor and wall along with the full set.
