What B2B Buyers Should Specify

  • Density vs firmness
  • ILD test meaning
  • Compression set
  • Layer-by-layer BOM control

Factory Notes from the Mattress Database

Density measures material mass; ILD measures how much force is needed to compress the foam.

A high-density foam can still be soft if its ILD is low.

Requesting both numbers prevents suppliers from substituting a cheaper foam that looks similar in photos.
