Outdoor wood furniture can be made out of many different materials including teak, shorea, cedar wood and even eucalyptus. Teak wood and shorea wood patio furniture will age to a warm gray tone when exposed to the elements. This process does not harm the integrity of the wood, at all. Cedar patio furniture has been used for decades and is has a very aromatic scent. Eucalyptus patio furniture has been growing in popularity and like shorea outdoor furniture it is comparable to teak but is less expensive.
