They come very well packaged, as you can see in the first image, so you have to wait a little for them to “inflate.”  They are very comfortable, you can really feel the good quality.  They are spongy but very firm.  It says in the description that they are light and let's say that they are but I feel they have a little weight to them, that kind of weight that lets you know that something is of good quality, which for me is perfectly fine.  I liked them a lot!
