Your articles provide lots of interesting material on making evaluations based on the materials and densities used.
What is your opinion on the following mattress make up:
20cm base layer of Bultex foam (38 kg/m3 - 3.5 kPa)
7cm layer of Sensus heat-sensitive memory foam (50 kg/m3 - 1 kPa)
2cm layer of polyester quilting (25 kg/m3 - 1.2 kPa)
How firm or soft would it be?
What is comparable in your range?
Just to clarify on my previous email the quilting layer should have said 250 g/m2 polyester... not 25kg
