ChiliPad Dock Pro
The subscription-free water-cooled alternative to Eight Sleep — premium climate, no ongoing fees, no HRV tracking.
Eight Sleep Pod 6
The most sensible Eight Sleep yet — the Pod 6 shrinks the hub by half, adds 9x more sensors, changes temperature 20% faster and, for the first time, sells single-sleeper Solo sizes from $1,999, while the dual-zone queen drops to $2,899. The catch is unchanged: an Autopilot membership ($199–$399/year) is mandatory, and the warranty length depends on which tier you pay for.
Eight Sleep Pod 4
A premium smart sleep-climate system — dual-zone water cooling/heating, HRV tracking, subscription required.
Eight Sleep Pod Cover Pro
Pod 4 climate and tracking on your existing mattress — cheaper entry into the Eight Sleep ecosystem.
OOLER Sleep System
Legacy Sleepme water-cooled system — solid track record, app scheduling, superseded by Dock Pro for new buyers.
ChiliPad Cube
The budget water-cooled pad — real water cooling for $719 a side, but remote-only, no scheduling and a warmer coldest setting than Chilipad 2.0.
BedJet 3
The air-flow alternative to water-cooled systems — no water management, more affordable, less rigorous temperature control.
Eight Sleep Pod 3
Most of Pod 4's features at a lower price — solid value when discounted, slightly narrower climate range than Pod 4.
Eight Sleep Pod 5
The maximal Eight Sleep — the Pod 5 Ultra adds an adjustable base, a top-down hydro-powered blanket, built-in audio and snore mitigation, but at $6,099+ it costs about 1.5× the Pod 4 (~$4,000). The core dual-zone climate and HRV tech are the same as the Pod 4, which remains the value. Note: Eight Sleep replaced the Pod 5 with the Pod 6 on 23 September 2026 — check remaining Pod 5 stock against Pod 6 pricing.
Sleep Number Climate360
Smart-bed approach to sleep climate — climate built into the mattress, not added as a layer. Premium pricing.
Slumber Cloud DryLine Cooling Sheets
Cooling sheets, not active climate — meaningful passive heat dissipation at the budget tier.
Tempur-Breeze Pro Cooling Mattress
Passive cooling — not active climate. Premium Tempur build that runs cooler than standard memory foam without a hub.
