Verdict: Eight Sleep Pod 4 outperforms on features with dual-zone AI tracking and alarms per its 2024 specs, but costs over three times more than the 2019 Chilisleep Ooler at $2549 versus $699. Ooler covers a wider 55-115°F range without subscriptions while Pod 4 requires one for full functionality. Pod 4 wins for advanced users despite the premium.
