Full-Width Topper Fold & Recovery Test

Scheduled — no results yetCS-TST-004

Product revision: CS-MATTRESS-2026-08-A

Internal engineering test — not an EN, ASTM, CPSC or medical certification.

What are we testing?

Can the structural full-width topper form and retain a fold by accident in a normal sleep situation — under the influence of a small child or a sleeping adult — rather than through deliberate folding or play?

Why this test matters

Any topper can be folded deliberately, or end up folded during wild play. That is not the safety-relevant question.
What matters is whether a fold can occur by accident in a normal sleep situation, and whether the construction recovers on its own.
The comparison point is loose bedding, which can fold and stay folded.

Method basis

Co-sleeping.com internal protocol. We publish measured behaviour (retained overlap, recovery time) rather than an invented “infant-safe” certificate.

Protocol

Protocol under development together with third-party test laboratories.
