Fitting to its name, the New England Arbors Roosevelt Composite Pergola is grand, impressive, and sets a dramatic stage for your outdoor living space. At 12 x 12 feet, this pergola is constructed of a revolutionary blend of vinyl and recycled wood pulp. This results in a pergola that looks like wood but has the benefits of maintenance-free vinyl. Even up close, you'll have a hard time believe it's not real wood due to its gorgeous cedar color and natural feel. But the truth is, it's better than wood. To keep it looking great, all you have to do is rinse it with a garden hose to clean it. It will look like new year after year.DimensionsOverall (includes roof): 171.5L x 171.5W x 105.75H in.From outside posts (excludes roof width): 144L x 144W x 105.75H in.Inside posts: 134L x 134 x 94H in.Posts: 5L x 5W in.Weight: 235 lbs.Assembly for the Arcadia Composite Pergola takes two people approximately 4 hours and you'll need a drill, level, ladder, and measuring tape.
