Observed recovery response
Earlier, better-timed light exposure is associated with earlier sleep onset the following night.

The bed
Each bed carries crisp Bellino fine linens, hypoallergenic pillows and custom-designed throws, part of the environmental calibration that supports recovery after a day of movement.
The bath
Spacious travertine walk-in showers, marble vanities and premium Aesop amenities support the wind-down sequence and morning activation.
Movement and recovery
The suite keeps training and recovery protocols within reach without leaving the floor, which matters when we are measuring how daytime load moves overnight physiology.
Technology
Premium WiFi, Apple TV and bedside controls for blackout shades and lighting. The Proper TV app orders in-room dining, requests amenities or books a Proper Club Lounge session.
Suite description, dimensions and amenities are drawn from Santa Monica Proper's published guestroom information. Square footage is approximate and actual suites may vary. Sleep Week is a proposed collaboration; the Coherence Recovery layer described above is designed inside this base building.
Three-night mattress comparison
The reference surface for Thermal Design. Independently pocketed coils give zoned support with airflow through the coil layer, and a thin latex comfort layer keeps contour shallow. Most guests recognise it as familiar, which makes it a useful biological baseline for the two nights that follow.
Construction, top to base
Comfort
Natural latex, ~5 cm, shallow contour, fast recovery
Transition
Zoned foam rail to reduce shoulder and hip pressure
Support
Individually pocketed coils, firmer through the lumbar zone
Base
High-density perimeter for stable edge exit

Measured on this night
01
One per night
A single surface is used for the full sleep opportunity, never split across a night, so the Thermal Design variable stays isolated.
02
Everything else fixed
Circadian, acoustic, atmospheric, behavioral and nutritional inputs stay constant while only the thermal surface changes.
03
Blinded where practical
Order is rotated and surface identity withheld until the review to limit expectation effects on the recovery record.
04
Ranked on your data
Objective metrics from the Human Coherence Dashboard™ are weighted first; morning ratings break close results.
Surfaces are premium consumer specifications, not medical devices. Sleep Week does not sell mattresses; any commercial relationship with a manufacturer is disclosed. Three nights indicate a direction, not a certainty, the recommendation is a specification to trial at home, calibrated against your own measured recovery data.

A visible relationship across three nights is a hypothesis to test at home, not proof of cause.
