Cofounder of Superhuman Chambers · About the author. General information, not medical advice. No independent clinical review is claimed.
Chilipad 2.0 circulates distilled water from a bedside Dock through a Hydrolayer pad to cool or heat one side of the bed. Sleepme gives a range of 55°F to 115°F, and it suits one sleeper who wants a nightstand remote and no subscription. The catch is that the $1,699 kit covers only your half, and Sleepme doesn't publish power draw or noise level.
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the Two Sleepers option nor the add-on Companion system showed a price, and power draw, noise and running costs are unpublished.

THINK TWICE IF
| Exact variant | One Sleeper (single zone), Half Queen: Dock, Hydrolayer, cover and nightstand remote |
|---|---|
| Temperature range | 55°F to 115°F (cools or heats) |
| Zones in this kit | One zone, for one side of the bed. You can add a Companion system later for the other side |
| Mattress fit | Mattresses 10 to 16 in tall. Works with adjustable and split-adjustable bases |
| Controls and sensing | Nightstand remote with two USB-C ports (one for power, one for charging accessories) and a free app. Optional presence sensing can start the sleep schedule when you get into bed early. Works with or without Wi-Fi |
| Water | Needs distilled water. Sleepme says the redesigned Dock has a higher-capacity reservoir so you refill less often, but it gives no volume |
| Subscription | None required |
| Power draw and noise | Not stated by the manufacturer (no wattage or decibel figure published) |
| Dimensions | 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. |
| Materials | 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. |
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.
Two-year limited warranty, with an option to extend it. The product page doesn't show the extension's price or terms.
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.
Chilipad 2.0 is Sleepme's water-based system for cooling and heating a bed. A bedside Dock circulates distilled water through a Hydrolayer inside a machine-washable, waterproof cover. Sleepme gives a range of 55°F to 115°F. The $1,699 One Sleeper Half Queen kit covers one side of a 10 to 16 inch mattress, with no subscription and no need for Wi-Fi. Sleepme doesn't publish power draw, noise level or reservoir capacity, so running costs are unknown. It comes with a two-year limited warranty and a 30-night trial.
