What a 100 means for smart mattress covers
An active-temperature cover judged on the range it can hold, how precisely, and what it senses.
This score compares Eight Sleep Pod 4 against 18 other smart mattress covers only. It is not comparable to a score in another category — a mattress and a sleep mask share no attribute, so a single ranking across them would be arithmetic without meaning.
How the score was reached
Function & Control
- Sleep-stage tracking
- Heart rate / HRV
- Learns and auto-adjusts
Temperature & Airflow
- Dual-zone control
- 55°F range
- Temperature regulating
Not declared
Eight Sleep publishes nothing about durability & care, verified & non-toxic. These are left out of the score rather than scored as zero — silence is not evidence of a failing. They are why the score is capped at 90 for this product.
