ILD (indentation load deflection), also called IFD (indentation force deflection) is a measurement of the force required to compress a material by 25% of its thickness. While ILD can be a helpful technical tool for characterizing a sheet or layer of latex, it is often misused or misunderstood.
At Savvy Rest, we recommend customized layer configurations for mattresses based on years of experience, customer interviews and customer feedback, not ILDs.
