What Is the Global Sleep Score™ (GSS™)?
The Global Sleep Score™ (GSS™) is a worldwide certification initiative that evaluates and recognises accommodation providers based on the overall sleep environment they provide to guests.
The GSS™ is built on five scientific pillars:
- Mattress Hygiene Index™
- Air Quality & Ventilation
- Light & Noise Control
- Bedding Quality & Cleanliness
- Sleep Experience & Amenities
Each hotel receives a Global Sleep Score (0–100) and an official Cloud Rating™ (Cloud 1–5), along with a detailed Sleep Environment Report and certification badge.
GSS™ allows hotels to show guests something they care deeply about:
high-quality, trustworthy sleep.

Why Sleep Environment Quality Matters
- Guests spend 6–9 hours of their stay in bed — more than any other activity
- The average adult releases up to 52 litres of moisture into the mattress each year
- Mattresses can harbour millions of bacteria, dust mites, and allergens
- Air quality, noise, and light leakage directly impact sleep quality
- 82% of guests say sleep quality affects whether they return
- Influencers are now performing “sleep checks” in hotel rooms globally
- Clean, healthy air reduces odours, allergies, and negative reviews
Sleep is the new wellness priority — and GSS™ makes it measurable, marketable, and certifiable.
The Global Sleep Framework™
At the core of GSS™ is the Global Sleep Framework™ — a structured, science-led approach that transforms sleep environment quality into a measurable, standardised, global benchmark.
Developed with sleep hygiene specialists, environmental scientists, and hospitality experts, it ensures hotels can:
- Improve sleep environment consistency
- Make sleep quality visible to guests
- Identify issues proactively
- Benchmark against global standards
This framework supports properties in achieving higher Cloud Ratings year-round.
