Eight Sleep Pod and Sleepme Dock Pro (formerly ChiliSleep) are the two leading bed cooling systems. Both use water-based temperature control. Both work with your existing mattress. The differences are price (Eight Sleep is roughly 2x), sleep tracking (Eight Sleep has it, Sleepme does not), and subscription requirement.
Verdict
Winner: Eight Sleep Pod for biohackers and data-lovers; Sleepme Dock Pro for buyers prioritizing pure cooling at half the price
Eight Sleep adds sleep tracking, AI Autopilot, and snore detection (Ultra only). Sleepme delivers the same dual-zone cooling without subscription and at half the price.

Who should buy which
Eight Sleep if: You want sleep optimization platform, AI adjustments matter to you, you do not mind subscription.
