After researching many pergola manufacturing companies, we chose Backyard Discoveries.  The price was the best and photos and reviews appeared to be of good quality.  I was relieved when the boxes were delivered and I could confirm the quality of the manufacturing and design.  The instructions were well written, and the assembly was clearly well thought out.  My son and I were able to easily assemble the pergola in about 8-10 hours on a Saturday.  I was impressed at how easily it went together with pre-drilled holes everywhere and top quality hardware.  The product and company exceeded all my expectations.  In sunny California we enjoy the pergola almost every day.  I would highly recommend this product to anyone considering a pergola to enhance their property.
