Just received our lounge chairs.  They came well packaged and were very easy to assemble. The only assembly was attaching the 4 legs. The packaged tool kit included extra screws and the necessary Allen wrench. Piece of cake. Order updates and tracking updates were also very good. 
The cushion is comfortable and has a stretchy strap at the top left and right corner of the back cushion to keep the cushion in place. My only disappointment (while minor) is the height of the lounging seat. A bit low but overall fine. The black frame is about 12 inches before cushion. 
I wish the finished height with cushion was closer to 15- 16”.  But a minor issue. Otherwise very pleased with the purchase thus far. It was a very modest investment so hope it survives a few MW winters. (I will purchase a cover)   But it definitely provides good comfort and a clean, modern look for a summer of significant outdoor living.
