Memory Foam Density

Choosing the correct density memory foam mattress or topper

You may be aware that memory foam is specified as being of a certain weight or density. This is usually expressed in kilos (or kgm) and usually varies between 40kg and 80kg.

What this refers to is the weight that the memory foam would be if you had one cubic metre of it. So, a cubic metre of “45kgm” density would weigh 45kg and a “75kgm” would weigh 75kg.

All Sehriech memory foam mattresses and toppers are 75kgm density which is at the high end of top quality memory foam.
