My husband (68) and I (71) were very surprised with the Pergola we purchased. We put the whole unit together and it took a couple of hours each day for I believe 4 days. We took our time. Followed directions very good ones we thought. Very surprised with the top and curtain material and metal. Now we can sit in our Hot Tub with privacy curtains. We are so happy with the way it looks, and it sits perfectly in a spot where the weather in our backyard is protected from the winds. Hope this will help in your decision if you purchase this product. I do feel we will need to replace the top material. it is great however it is so snug which is good but looks like it may not last a long time. The hardest part was stretching the material on top. Make sure you do this before placing the bottom together like it says in the instructions.
