Choose if	Couples who want separate bed temperatures on their current mattress and will keep paying for Autopilot.	You want to cool or heat your half of a 10 to 16 inch mattress from a bedside remote, with no subscription and no need for Wi-Fi.
Main trade-off	Autopilot adds $199 to $399 a year, and a Pod 5 bought secondhand or from a marketplace isn't covered by Eight Sleep's warranty.	The $1,699 kit covers one side only, neither the Two Sleepers option nor the add-on Companion system showed a price, and power draw, noise and running costs are unpublished.
Key specifications	Temperature range: 55°F to 110°F, set separately for each side of the bed Water or air: Water. The Cover has a water cord at the foot of the bed for the Blanket add-on. A launch report says the Hub has a built-in reservoir in place of Pod 5's removable tank Noise: Eight Sleep publishes no decibel figure. A launch report calls the Hub quiet rather than silent Hub power: Input 120/240 V AC, output 550 W at 12 V DC. Average power draw isn't stated Subscription: Autopilot required. Standard $199 a year (2-year warranty), Enhanced $299 and Elite $399 (5-year warranty). Monthly: $17, $25 or $33 Bed sizes: Standard, for one or two sleepers: Full 54 × 75, Queen 60 × 80, King 76 × 80, Cal King 72 × 84 in.

Exact variant	Pod 6 Standard, Queen 60 W × 80 L (Cover and Hub), the current equivalent of Pod 5 Core, Queen	One Sleeper (single zone), Half Queen: Dock, Hydrolayer, cover and nightstand remote
Dimensions	Cover: Queen 60 in W × 80 in L, 1 in thick. Hub: 16.54 in L × 7.87 in H × 6.50 in W, 15.2 lb. Eight Sleep doesn't list the Cover's weight.	Not stated by the manufacturer. The product page shows no dimensions or weights for the Dock or the Half Queen Hydrolayer. The system fits mattresses 10 to 16 inches tall.
Installation	The Cover fits over your mattress like a fitted sheet. Eight Sleep says it works on any mattress and gives no thickness limit. The Hub can slide under the bed or sit on or near your nightstand. It's 7.87 in tall, so measure first if you want it under the frame. It takes 120/240 V AC input. Eight Sleep lists no installation service, plumbing or electrical work.	You set it up yourself. Stretch the cover and anchor band over the mattress like a fitted sheet, then place the Hydrolayer inside and secure it with S-hooks. Connect the water hose and power cord, and add the included System Cleaner packet. Then fill the Dock with distilled water until the screen shows the Hydrolayer is full. It works on adjustable and split-adjustable bases. Sleepme doesn't recommend it for a top-split mattress if both sides need to raise and lower independently.
Materials	The Cover's top fabric is 100% polyester. The side fabric is 46% polyester, 44% rayon and 10% spandex. The inner fabric is 96% nylon and 4% spandex. Eight Sleep lists no OEKO-TEX or other textile certification for the Cover and doesn't say what the Hub is made of.	The Hydrolayer is a water-filled membrane with ultra-thin internal channels. The cover is breathable and machine-washable, with built-in waterproof protection, but Sleepme doesn't give its fabric composition. Sleepme says the core electronics are designed and assembled in the USA, and the soft goods are made by partners in Asia.
Warranty	Two years with Autopilot Standard ($199 a year), or five years with Enhanced or Elite. Coverage starts on delivery and needs an active membership for the whole term. It covers only Pods bought from eightsleep.com. Pods from third-party marketplaces, unauthorized resellers or secondhand sales aren't covered, and the warranty can't be transferred. The warranty page still lists Pod 5 among the Pods it covers. Upgrading to a new Pod ends the old Pod's warranty.	Two-year limited warranty, with an option to extend it. The product page doesn't show the extension's price or terms.
Returns	30-night trial with free returns. Email Eight Sleep support within 30 calendar days of delivery, and it sends a prepaid return label. Refunds typically take 5 to 10 business days after approval. Shipping to a freight forwarder voids the return. The policy doesn't say whether Autopilot fees are refunded or what condition the Pod must be in.	You get a 30-night sleep trial with free returns. A return starts with a Return Authorization, and refunds are issued within 30 days of receipt. Outside the contiguous US, you pay return shipping. Sleepme can't process returns for items bought through third-party retailers. Orders placed November 4 to December 25 get an extended trial through January 25 of the following year.
Unresolved questions	Average power draw and yearly electricity cost Noise level in decibels Reservoir capacity and how often to refill or clean it What still works if you cancel Autopilot after the first 12 months Whether Autopilot fees are refunded if you return the Pod during the trial Whether Pod 5 owners get upgrade pricing Whether the Hub has a UL or ETL safety listing Whether and when Eight Sleep gets the FDA clearance it says it's pursuing Long-term reliability of the new Hub, which went on sale in September 2026	Dock power draw and yearly electricity cost Measured noise level, since Sleepme says only that the 2.0 Dock is quieter than earlier generations Dock and Half Queen Hydrolayer dimensions and weight System Cleaner price and replacement schedule Price and terms of the extended warranty Prices for the Two Sleepers option and the Companion system Long-term durability and leak resistance of the Hydrolayer
