Factory Notes from the Mattress Database
Firmness should be translated into materials, not left as a subjective word.
A 13 gauge spring feels firmer than a 15 gauge spring when the rest of the build is similar.
Quilting fiber and cover tension can change first-touch softness even when the support core stays the same.

FAQ
How should OEM buyers describe firmness?
Use a 1-10 target plus material details such as foam ILD, spring gauge, comfort layer thickness and sample reference.
Can the same mattress be made softer?
Yes. Softer comfort can come from lower ILD foam, extra plush layers, pillow-top construction or a different quilting package.
How should buyers use this sleep library topic in a product brief?
Use the topic as a checklist, then convert each decision into measurable fields such as density, ILD, spring gauge, fabric weight, height, packaging and certification requirements.
How does the mattress finder help visitors on this page?
It guides visitors through construction, firmness, height, buyer program and OEM features so they can compare suitable Guangyun platforms before sending an inquiry.
