Sleeping-Surface Gap Formation Test

Scheduled — no results yetCS-TST-006

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

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

What are we testing?

Can normal or adverse loading create an exposed gap between the underlying modules on the final sleeping surface?

Why this test matters

Gaps at the sleeping surface deserve serious attention — particularly for non-mobile infants.
A modular substructure makes this a directly testable interface question.

Method basis

Co-sleeping.com internal protocol. Two different things are measured and reported separately: internal module separation underneath the topper, and any exposed opening at the final sleeping surface. This is an engineering test — not an “entrapment certification”.

Planned procedure (draft protocol)

1Record baseline: module separation, surface profile, connectors in normal installed condition.
2Apply 90 kg distributed load directly over a junction; repeat with 120 kg.
3Apply 90 kg load 250 mm to one side of the junction.
4Apply opposing loads on adjacent modules where physically realistic.
5Repeat after topper-migration cycling and repeated-load durability cycling.

Loads / conditions

90 kg distributed over junction
120 kg distributed over junction
90 kg offset 250 mm

What will be recorded

Separation between structural modules underneath
Any visible/exposed gap on the final sleeping surface (with rigid scale in frame)
Topper indentation above the junction
Topper displacement
Recovery after unloading

Result

Scheduled

This test has not been run yet under the current documentation protocol. No result is published until a dated, signed internal test record exists for the stated product revision.
