Free Shipping. Uwharrie Chair creates indvidually hand-crafted outdoor furniture in either Pressure-treated Pine or Premium Uwharrie Polymer. Pressure-treated Pine is a hand-selected domestically harvested lumber product, while Premium Uwharrie Polymer is a recycled pre-consumer high-density vinyl. Both require no additional protection from exposure or weather, and both are available in solid finish or Wash. A wash color is essentially diluted paint; it allows more of the natural coloring to come through and offers a more distressed and rustic look. All Uwharrie Chair products have a lifetime guarantee against insect infestation, water damage and rot, and all are shipped with stainless steel hardware.
