You'll probably look for many of the same qualities in outdoor tables, chairs, and sofas that you value in interior tables, chairs, and sofas - durability, comfort, and style (and of course price). The main distinction is that patio furniture must withstand exposure to the elements outside. While there is no such thing as 100% weatherproof patio furniture, there are significant distinctions in the materials utilized.
For millennia, wood has been a favored raw material for furniture. It has a natural beauty, is relatively easy to work with, and provides a strong framework for tables, chairs, benches, and other furniture. When it comes to outdoor use, though, not all woods are made equal. Many softwoods, such as pressure-treated pine, cedar, and fir, are inexpensive and extensively used for indoor furnishings, but they do not stand up to the weather and must be protected at all times while not in use. Hardwoods, on the other hand, are significantly more resilient to weather and can live for decades if properly cared for. On the flipside, they are often more difficult to form and more expensive than softwoods. Hardwoods, on the other hand, have significant variances.
Teak is without a doubt the most popular wood for outdoor furniture. Because of its great demand and limited supply, the price of this fine-grained hardwood has skyrocketed. Teak, on the other hand, has a number of qualities that make it perfect for outdoor use. It is extremely sturdy, and unlike many types of wood, it does not warp, split, or become brittle. This is due to the fact that teak is water resistant and does not expand or contract during the drying process. It contains a large amount of natural oil, making it very resistant to rot, decomposition, and insects. Teak is the most durable wood against the elements, lasting up to fifty years! If left untreated, it can patina into an appealing silver-gray over time, or it can maintain its lovely honey brown color with minimum oiling. This attractive wood is used in at least a few pieces by most patio furniture manufacturers. Skagerak and Skargaarden, for example, appreciate teak's natural beauty and use its inherent strength to create beautiful and exquisite outdoor lounge and dining furniture lines. It requires little maintenance and can be cleaned with light soap and water.
One of the few hardwoods tougher and heavier than teak is this reddish-gold Southeast Asian timber. Heat increases the strength (modus of rupture) and flexibility (modus of elasticity) of the material [Noh & Ahmad 2017]. Shorea (also known as meranti) is harvested under strict guidelines to ensure that it, like many other hardwoods used for outdoor furniture, is sustainable. It also has a high oil content, which protects it from insects, prevents rotting, and protects it from the elements. If not oiled periodically, shorea develops a silver-gray patina that can last up to fifty years. It does, however, come at a significantly lesser cost. The single significant disadvantage of shorea is that few merchants sell it, owing to public apprehension.
This tough Australian hardwood grows quickly, lasts a long time, and costs far less than teak. It has a rustic charm due to its natural washed appearance, which will develop into a silver patina if not oiled regularly. It's resistant to the elements and rot, and its oil functions as a natural pesticide. However, a sealer is recommended to improve eucalyptus insect resistance and reduce the negative impact of uneven moisture retention.
Unlike many of its hardwood cousins, Central and South American ipe (a.k.a. ironwood) has a deep rich colored grain that fades slower when exposed to weathering [Jankowska, Reder, Goofit 2017]. It has a high natural oil content, which aids in its resistance to insects, decomposition, and fungi. Its dense, rigid structure protects it from physical damage like denting, warping, and cracking. Ipe requires a lot of preparation when cut and bonded together, even though it can survive up to forty years.
It's critical to understand the advantages and disadvantages of various material possibilities before making a decision. Assess how well each fits your personal preferences and interests, as well as the needs of your residential or commercial environment. Because each circumstance is different, choosing the "best" material for outdoor patio furniture requires matching your personal needs with the intrinsic attributes of each commodity.
