Substitute a known material into a known article?

Any special rules apply to this, or is just the usual novelty & non-obviousness?

Let me be a little more clear:
 
Taking a metal chair (known) and plastic (known) to make a plastic chair (assume unknown).

Other than useful, no special rules.  Obviousness would appear to be the most relevant, given the modest amount of information provided.

Cannot speak for US law but there is some guidance in WIPO Guidelines  PCT/GL/ISPE/1 13.14(a)(i)  that indicates that if the substitution does not involve any surprising effect ie. that it is a simple substitution of a certain material by another aving the same or similar properties then you would have difficulty in establishing a a problem to be solved from which a problem to be solved could be established - or simply the substitution would be obvious.
