Mattress Motion Isolation Explained

Motion isolation describes how well a mattress limits movement from traveling across the sleep surface.

Foam response

Slow-response foams often damp movement strongly because they absorb energy and rebound gradually.

Latex response

Latex is more elastic and can transmit more rebound depending on layer thickness and support structure.

Coils

Individually encased coils generally reduce cross-bed coupling compared with traditional connected spring units, but movement can still travel.

Use model-level evidence

Construction clues are useful, but couples who are very sensitive to movement should rely on model-specific testing where possible.
