Eight Sleep Pod 4: a EUR 2,500 way to fix something a window can fix
The temperature science is real. The price, lock-in, and software subscription are extreme. Worth it for a narrow band of buyers who genuinely can't cool their bedroom.
Guide

Vetted under the Codex charter
We only stock products that pass our ingredient, evidence and sourcing review. If a SKU stops meeting the bar, it's delisted — full stop.
