Choose if	Couples who want separate bed temperatures on their current mattress and will keep paying for Autopilot.	You want water cooling or heating on both sides of a King for about the price of one side of Chilipad 2.0.
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.	You give up the 2.0's two-year warranty, bedside remote and quieter Dock, and each Dock needs $88 of cleaner a year.
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. Solo, for one sleeper: Twin, Twin XL, Queen, King and Cal King Sensors: 18 in the Cover, up from two on Pod 5	Temperature range: 55°F to 115°F (13°C to 46°C), cooling or heating Zones and sizes: Two Sleepers has two temperature-controlled zones in Queen (out of stock), King and Cal King. A retailer listing says the two-person version uses two Docks. One Sleeper sizes and prices weren't shown Power: AC 100 to 240 V, 50 to 60 Hz, 235 W maximum rated power per Dock. No average draw is published Water: Holds 1 liter when full. Use distilled water, not tap or reverse osmosis water. The manual calls for 1 gallon of distilled water per Dock Controls and app: Buttons on the Dock, or the app for sleep schedules and Warm Awake. Runs without internet, but app control needs it. No subscription fees Upkeep: One System Cleaner packet and a water top-off each month per Dock. Twice a year, clean the grille and reservoir, then drain and wash the pad Noise: Not stated by the manufacturer. Sleepme says only that the 2.0 Dock is quieter
Exact variant	Pod 6 Standard, Queen 60 W × 80 L (Cover and Hub), the current equivalent of Pod 5 Core, Queen	Chilipad 1.0 (the renamed Dock Pro), Two Sleepers, King: two temperature-controlled zones
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. Neither the product page nor the Dock Pro manual gives dimensions or weights for the Dock or the topper. The manual asks for 6 inches of clearance around the Dock's front grille and back vent. Sleepme also asks for at least 2 inches between the mattress and the headboard or footboard, so the connector fits.
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. Depending on the pad, the topper goes on like a fitted sheet or slides on from the side. Plug in the Dock, attach the hose and fill the reservoir with distilled water until the water droplet icon disappears. The manual says that takes about three refills, and Sleepme says frequent top-ups are normal for the first few weeks. The Dock can sit at the head or foot of the bed or on a nightstand, and Sleepme recommends a surge protector. On a split adjustable bed, Sleepme says you need two one-person systems to cover the whole mattress. Put the connector at the foot.
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 kit is the "Legacy 1.0 Dock & 1.0 Chilipad Pro Cover." Sleepme calls the 1.0 topper a functional one focused on temperature control, while 2.0 gets a performance-grade cover. It doesn't give the topper's fabric or the Dock's materials. The manual says to drain the pad, machine wash it cold on a gentle cycle and tumble dry on medium.
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.	One-year limited warranty, per the product page. Sleepme's warranty terms give Dock Pro control units and Pro mattress toppers one year each. They cover defects in materials and workmanship, and Sleepme repairs or replaces at its discretion. Exclusions include cosmetic damage, accidents, misuse, improper storage, commercial use and normal wear on the pad. The manual says skipping its maintenance steps voids the warranty. Sleepme may charge shipping or handling fees on a claim, though not if you send the item back within the first 30 days. Sleepme sells a Protection Plan, but the warranty page gives no price or length.
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.	There's a 30-night sleep trial with free returns in the contiguous US. You start a return at Sleepme's Returns Center, and refunds are processed within 30 days of Sleepme receiving the product. Outside the contiguous US you pay return shipping, and expedited shipping fees aren't refunded. Sleepme can refuse a return or deduct from the refund if parts are missing or the system is used or damaged beyond what's reasonable. Final Sale items can't be returned, but the 1.0 listing carried no Final Sale label. Purchases made November 4 to December 25 get a trial through January 25 of the following year. The trial covers purchases from Sleepme's own sites and its official Amazon, eBay and Walmart pages. If you buy from another retailer, Sleepme can't process the return.
