Q: I received this chair today and definitely regret buying it. The off gasses made me and my son both sick with difficulty breathing and sore throats. There was no odor however some chemicals do not have a smell. There is formaldehyde per the package insert. Wish I had known this before buying. The reviews seemed to convince me that it was also pretty comfy but sadly I would not want to sit in this chair for More than a few minutes. It's very firm and not the chair I was hoping for. It's currently outside off gassing and will most likely keep it because I'm too lazy to pack it back up. It will probably grace the corner in spare room to torment any guests we have in the future.

A: negative

Q: I haven't used these products yet, the raincoat used before was very heavy. It's very inconvenient to put on. So I tried this raincoat, it feels great to put on. There is no sense of obstructing action. When I opened the package, I found a variety of raincoats in different colors, each of us can choose the color we like. I think we can take it with us on the field trip. Because it was raining hard days ago, it was I who carried a raincoat like this I won't get caught in the rain, I don't even feel it. It's a great feeling. A raincoat is long enough, it won't get your knees wet. That's not what other raincoats can do. So I suggest you take a raincoat like this. It won't take up your space and it will bring you convenience.

A: positive
