Hi
From what I have learned here this seems to be a decent foam however please comment if you know otherwise or have an opinion.
2" 4 lb Premium Quality High Density/HDX Memory Foam
It’s probably made by Sleep Innovations which is an American manufacturer.
I don’t know the other properties of the foam (response rate, temperature sensitivity, breathability, relative softness etc) but at least it has a money back guarantee so you can test it for yourself with little risk
