Polyurethane Specs in the US vs. Brazil

Mattress Talk General Mattresses Questions

]Dear all,

I am moving from Brazil to the US, and I wanted to check for equivalents

I have a poly foam mattress in Brazil with density of 28 kg/m3, which has an ILD at 40% (not 25%) of 145 Newton.

Would an US foam mattress of HD36 and IDL at 25% of 35LB be equivalent?

I sincerely appreciate the help!
