Though it looks like real birch, this nature inspired furniture for Woodrich® is actually made of aluminum. The birch-like finish is the result of a hand-applied finish of all weather, resin material. Each chair has a Viro woven seat and back, which adds beauty and assures comfort. The cushions and pillows are covered in Sunbrella® fabrics. The furniture is fully assembled for stability and comes with a five-year warranty on the frames.
