For durability and a lifetime of carefree maintenance, it's hard to overstate the advantages of furniture made from today's high-density polyethylene (HDPE).  Poly furniture beats wood hands down regarding it withstanding the elements, including the sun's hot rays, winter's ice and intense summer downpours. 
There's no need to bring poly inside no matter what the season-it can be left outside all year-round.  Poly will hold its color for decades with minimal fading.
Unlike wood, poly won't rot, split or crack, and is impervious to insect damage.  Plus, because the color runs thoughout the lumber, small nicks and scratches never need to be touched up.
Finally, poly furniture is easy to keep clean.  An occasional washing with mild detergent and rinsing is all that's needed to keep it looking like new.
