Eight Sleep Pod 4 vs. Pod 5
A generation apart, but the same temperature range, the same sensors and the same subscription. Here is what the extra money actually buys — and when a used Pod 4 is the better decision.

The short answer
If you already own a Pod 4, keep it. The Pod 5 is a refresh — redesigned hub, updated cover, a broader accessory lineup with the Blanket and Pillow Cover — not a new class of product. The published cooling and heating range is identical at 55°F to 110°F per side, the biometric tracking covers the same metrics, and Autopilot is still a subscription on both. If you are buying your first Pod, buy the Pod 5 new for the warranty and support, or hunt a clean second-hand Pod 4 and save well over a thousand dollars.
Pricing and specifications from Eight Sleep's published product documentation, September 2026. Pod 4 figures reflect its pricing while it was sold new. SleepSage has not completed in-lab thermal measurement of either generation, so no lab scores are assigned.
Pod 4
The generation that made Eight Sleep mainstream. Same core temperature and tracking experience as the Pod 5, no longer sold new, and by far the cheapest way into the ecosystem if you find a healthy unit.
Pod 5 — current
$2,799 with a redesigned hub, refreshed cover, 5-year warranty with membership, and the widest accessory lineup: Base, Blanket and Pod Pillow Cover.

What genuinely changed
A redesigned hub, updated cover construction, and two accessories that did not exist before: the hydro-powered Blanket and the Pod Pillow Cover. Those extend where the temperature reaches, not how cold it gets.
What did not change
The published 55–110°F range, independent sides, heart rate and HRV tracking, snoring detection, thermal and vibration alarms, and the Autopilot subscription requirement.
The subscription math
$199 a year on either generation. Over five years that is roughly $1,000 on top of the hardware, and dropping it costs you the automation and the extended warranty.
What we would do
- Own a Pod 4? Keep it. Spend the upgrade money on the Base or Blanket instead if you want more from the system.
- Buying your first Pod? Buy the Pod 5 new — the 30-night trial and membership-backed warranty are worth the premium on a water-cooled device.
- Value hunting? A clean second-hand Pod 4 delivers the same nightly experience for far less. Confirm the hub runs dry and the account transfers.
- Hate subscriptions? Neither Pod is for you. Look at the Chilipad or the Navien OptiSleep.
