The Chilipad Cube One Sleeper Half King cools and heats one side of a King bed with a water-based pad, and it needs no app or subscription. It's for one sleeper who wants active cooling and heating for $719 on sale ($799 list). The catch: Sleepme's FAQ says it cools the bed about 10°F below room air, so the advertised "as low as 60°F" depends on your room.
Cooling depends on room temperature, the standard warranty is only 1 year, and the product page doesn't publish power, noise or maintenance details.

The $719 is a sale price on Sleepme's product page for the One Sleeper Half King. It was marked "Save 10%" against a $799 list price. It sat under a "10% Off Original Chilipad" banner marked "No Code Needed." It isn't a coupon or member price. The page said "Ships in 1-3 business days." The Half Cal King showed the same sale and list prices, and the Half Queen was out of stock. Two Sleeper (dual-zone) prices weren't shown. The price is before tax, and ground shipping is listed as free to the 48 contiguous states.
A GOOD FIT FOR
One sleeper who wants active cooling and heating on their half of a King bed, without an app, Wi-Fi or membership.
THINK TWICE IF
| Exact variant | One Sleeper (single zone), Half King: Cube control unit, Cool Mesh Pad and remote |
|---|---|
| Temperature range | 60°F to 115°F, per the page's meta description. The visible copy says "as low as 60°F," and the FAQ says the Cube lowers bed temperature by about 10°F from room air. The visible page text gives no separate heating maximum. |
| Zones and sizes | One Sleeper (one temperature-controlled zone) comes in Half Queen, Half King and Half Cal King. A Two Sleepers option (two zones) is also listed, but its sizes and prices weren't shown. Sleepme says you can add a second single-zone system later for dual-zone control. |
| Controls | Buttons on the unit or the included remote (batteries included). No Wi-Fi, Bluetooth or app account |
| Under-bed clearance | Sleepme says the Cube fits under bed frames with 8 in or more of clearance |
| Subscription | None. The product page says "No Subscription Fees" |
| Power draw, water capacity, noise | Not stated by the manufacturer on the product page |
| Dimensions | Sleepme says the Cube fits any mattress and fits under bed frames with 8 in or more of clearance. It doesn't state pad or control-unit dimensions or weights on the product page. The page's "Specs" tab and "See Size Chart" link were empty. |
| Materials | The Cool Mesh Pad is water-based, and Sleepme says it has no electrical connections or wires. The page describes the Cube as a dual-sided topper ("Cool or Comfy"). It lists "Machine-Washable & Dryable" among the system's features but doesn't say which parts that covers. Sleepme doesn't state the fabric composition or the control unit's materials on the product page. |
The pad goes on top of your existing mattress, and Sleepme says any mattress works. It calls the Cube "plug-and-play" and lists "Easy Installation." The control unit fits under bed frames with 8 in or more of clearance. Sleepme says the Chilipad works with adjustable and split-adjustable beds. It recommends two single-zone systems for a split-adjustable bed and suggests putting the control units at the foot of the bed. You don't need Wi-Fi, Bluetooth or an app account. Sleepme doesn't state electrical requirements on the product page.
The Cube has a 1-year limited warranty, with an option to extend coverage. Sleepme's warranty terms give 1 year on the Cube control unit and 1 year on sleep pads. Exclusions include cleaning or maintaining the control unit, or washing the pad, in a way that doesn't follow Sleepme's instructions. They also include improper voltage or power supply, use outside the intended uses, and commercial use such as hotels or hospitals. Neither the product page nor the warranty page states the length or price of the extension (the Protection Plan).
There's a 30-night sleep trial with free returns. Sleepme's warranty terms say the trial runs 30 days from delivery, and you must request a return within that period. Sleepme must then receive the product within 30 days of the request. Returns within the first 30 days aren't charged shipping and handling, but expedited shipping fees aren't refunded. If you buy from an authorized dealer, the dealer's return policy applies. Sleep-system purchases made November 4 through December 25 get an extended trial through January 25 of the following year. The pages checked don't state refund timing, minimum nights or packaging requirements.
The Chilipad Cube is Sleepme's entry-level water-based pad for cooling and heating a mattress. The One Sleeper Half King covers one side of a King bed and was $719 on sale ($799 list) on October 13, 2026. You control it with buttons or the included remote, with no app, Wi-Fi or subscription. Sleepme's FAQ says it cools the bed about 10°F below room air, so the page's "as low as 60°F" depends on your room. The standard warranty is 1 year. Sleepme doesn't publish power draw, water capacity or noise, so running costs are unknown.
