Light
The strongest available lever on circadian timing.
- Circadian-aligned morning light
- Tunable white lighting
- Amber evening setting
- Near-total blackout
- Reduced device light
The engineered sleep suite
A room designed to be an instrument, not an amenity.
Seven inputs are monitored and controlled together. Each is changed on a schedule so its effect on the next morning can be observed rather than assumed.
Sleep engineering lab
Twelve engineered systems in one 926 sq ft plan.

Light
The strongest available lever on circadian timing.
- Circadian-aligned morning light
- Tunable white lighting
- Amber evening setting
- Near-total blackout
- Reduced device light
Observed effect pattern
Earlier, better-timed light exposure is associated with earlier sleep onset the following night.

The full specification
Every controllable input, written down.
Temperature
The body needs to lose heat to fall and stay asleep.
- Zoned room climate
- Active sleep-surface heating or cooling
- Guest-specific thermal schedule
Sound
Most awakenings are never remembered, but they are measurable.
- Acoustic treatment
- Noise monitoring
- White, pink or nature-based soundscapes
- Quiet-mode protocols
Air
Stale air is one of the most overlooked disruptors.
- HEPA filtration
- CO₂ monitoring
- Humidity monitoring
- Fresh-air strategy
- Target humidity range
Scent
Optional, guest-controlled, and off by default.
- Optional programmable scent cues
- Guest-controlled and allergy-aware
- No scent by default for sensitive guests
Nutrition
The last four hours before bed matter more than the diet label.
- Earlier, lighter dinners
- Caffeine and alcohol timing
- Sleep-supportive meal design
- Stable overnight energy strategy
Behavior
The routine is part of the room.
- CBT-I-informed routines
- Morning light
- Movement
- Wind-down sequence
- Consistent wake time
- Cognitive down-regulation
The base room, Performance Wellness Rooms, Santa Monica Proper
Stay active. Stay inspired. Stay in rhythm.
Sleep Week suites are built on the hotel's Performance Wellness Rooms: 926 square feet in the Landmark Building, designed by Kelly Wearstler, with movement and recovery tools already in the room.

The bed
Rest well to perform at your best.
Each bed carries crisp Bellino fine linens, hypoallergenic pillows and custom-designed throws for restorative sleep after a day of movement.
- Bellino fine linens
- Hypoallergenic pillows
- Custom throws
- Simmons Providence mattress
The bath
Recover and refresh in a spa-like bathroom.
Spacious travertine walk-in showers, marble vanities and premium Aesop amenities support the wind-down and morning routines.
- Travertine walk-in shower
- Marble vanity
- Aesop amenities
- Turkish cotton robes
Movement and recovery
Recovery tools already in the room.
The room keeps training and recovery rituals within reach without leaving the floor, which matters when we are testing how daytime load moves overnight physiology.
- In-room Peloton bike with on-demand classes
- Theragun for muscle recovery
- Strength and functional training equipment
- Proper Club Lounge: sauna, cold plunge, red light therapy
- Curated wellness minibar
Technology
Work and wellness on the same controls.
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.
- Bedside blackout shade control
- Bedside lighting control
- Apple TV and premium WiFi
- Proper TV app requests

Three-night mattress comparison
Three surfaces. One per night. Judged on your data.
The bed is a variable, not a fixture. Each measured night uses a different sleep surface while light, temperature, sound, air, bedding and pre-sleep protocol stay fixed, so any change in the record can be attributed to the surface itself.
The reference surface. 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 baseline for the two nights that follow.
Build, 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
Likely to suit you if
- You change position several times a night
- You share a bed but are not motion sensitive
- You run warm and want airflow through the core
Watch for: Coil transmission can register as micro-awakenings when a partner rises frequently.

01
One per night
A single surface is used for the full sleep opportunity, never split across a night.
02
Everything else fixed
Light, temperature, sound, air, bedding and pre-sleep protocol stay constant.
03
Blinded where practical
Order is rotated and surface identity withheld until the review to limit expectation effects.

Ranked on your data
Objective metrics 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, with your own numbers attached.
