1) Too early to comment on the product quality as I purchased it only a few days ago.
2) Assembly instructions were not good enough in the assembly sheet that came with the package. Video was a bit better, although not entirely.
3) Based on the online product description, the product seems to be made in the USA. However, the packaging and the product itself had "Made in China". Pasting the text from the website description below:

"This 4 Piece Rattan Sofa Seating Group with Cushions on your patio or deck, is great for get-togethers with family and friends. Made in the USA, this set includes two chairs, a loveseat, and a coffee table."
