I purchased 4 of these for around our fire pit. They are definitely not as firm looking as the picture depicts, when you sit in them they really spread out however they are fairly comfortable. 
I wouldn’t leave them out in the weather, as the sun will fade the cover material, and rain over time will destroy the foam chip filling.
The cover zips on and off for easy washing.
The colour teal is true to the colour shown online.
Over all I like them, they are great for laying back and star gazing.
