The bed
Each bed has crisp Bellino linens, hypoallergenic pillows, and custom throws, part of the setup that helps you recover after a day of movement.
The bath
Spacious travertine walk-in showers, marble vanities, and Aesop amenities support winding down at night and waking up in the morning.
Movement and recovery
The suite keeps workout and recovery tools within reach, without leaving the floor. That matters when we're measuring how your day affects your night.
Technology
Fast WiFi, Apple TV, and bedside controls for blackout shades and lighting. The Proper TV app can order room service, request amenities, or book the Club Lounge.

Three-night Hästens comparison · Powered by Hästens

The reference surface. Marquis is the lightest complete bed Hästens builds, the first place its materials, horsehair, flax, wool, cotton and Swedish pine, appear together. Because it feels familiar to most guests, it makes a clean baseline for the two nights that follow.
Construction, top to base
Top
Hästens top mattress, cotton and wool, shallow contour
Comfort
Layered horsetail hair, ventilating and naturally springy
Support
Bonnell spring system in a slow-grown pine frame
Base
Single-layer platform, low mass, stable edge exit

Night one · Surface A
Hästens Marquis®
A shallow, familiar shape. Pressure spreads evenly but not deeply, so side sleepers still shift position.
Night two · Surface B
Hästens 2000T®
Three spring systems free up the shoulder while supporting the lower back, which is usually why the second half of the night gets quieter.
Night three · Surface C
Hästens Vividus®
The deepest pressure relief in the rotation, and about as good as a mattress alone can get.
Relative score, 0 to 100, from spec sheets. These are samples, your own record decides the ranking.
01
One per night
One Hästens surface is used for the whole night, never split, so the mattress stays the only thing that changes.
02
Everything else fixed
Body-clock, sound, air, behavior and food factors stay the same. Only the mattress changes.
03
Climbing the collection
The rotation runs from the entry-level bed to the masterpiece build, so it's construction, not price, that shows up in your results.
04
Ranked on your data
Measured data from the Human Coherence Dashboard™ counts first. Morning ratings settle close calls.
Hästens, our mattress partner, supplies these beds. They are premium consumer products, not medical devices, and Sleep Week does not sell them. We disclose the partnership wherever it appears. Prices are estimates for a full bed system and vary by size and market. Three nights point to a direction, not a certainty. Treat the recommendation as a spec to try at home, checked against your own sleep data.

A pattern across three nights is a hypothesis to test at home, not proof.
We log suite conditions continuously and review them alongside your body's data. A pattern across three nights is worth testing at home, but it is not proof of cause.
