Review Content Sturdy All Weather Arbor This arbor is just one of several outdoor items that Ive purchased from Highwood USA. The arbor is made of weatherproof recycled plastic that looks like wood. The weathered acorn looks just like the pictures on the website. The item was well packed and had no damage. It was easy to assemble alone but two people is recommended due to its size. I anchored into the ground with metal anchors that I purchased at a local garden center.
