Frequently asked questions

What exactly comes with the Cube?

The Cube is a temp-controlled mattress pad controlled by an attached control unit with a water tank. As a new user, you’ll receive a reversible, hydro-powered cool mesh mattress pad, a control unit, and a remote to conveniently adjust mattress pad temperature. Our innovative product cools or heats your bed between 55-115°F to create a revolutionary, customizable sleep environment.

How do I set up the Cube?

View Instructional video here!

Real Simple magazine included the Cube in its list of best cooling mattress toppers in 2021. And it actually is real simple to use. Here’s the basic order of operations we generally recommend for new users:

  1. Mattress as base
  2. chiliPAD (connecting tubes can go at the head or foot of the bed)
  3. Fitted sheet
  4. Blanket or duvet on top (think of it as a refrigerator: if the door is left open, all the cold air will be let out; using a top layer traps the air to regulate your temperature preference!)

The control unit measures 12" x 12"x 12" and can be placed next to your bed. (While it can be placed under the bed, ensure there’s ample space for ventilation; a clearance of 18 inches on all sides is recommended).

How do I set a comfortable temperature? Does it have to be set low?

Since everyone is unique, it may take a few nights to find your own sweet spot. Some like it warm while others like it cool. Sleep studies show the ideal sleep temperature for optimal rest & recovery is 60-68ºF (15-20?C). Ultimately, if you are unsure where to begin, start at 65°F (18?C) and adjust up or down from there. No matter where you end up, temperature-wise, the Cube will help you master the art of getting amazing deep sleep!

Why is getting deep sleep so important?

Deep sleep helps your body and mind heal. Deep sleep has restorative power for us physically, including cell regeneration, a strengthened immune system, tissue and bone repair, and more. According to the CDC, more than one-third of American adults are not getting enough sleep on a regular basis. A good night’s sleep can help to maintain blood sugar levels, shed excess fat, and reduce the risk of metabolic diseases like obesity and diabetes.

Can I use the Cube on just half of our bed?

Yes! The Cube can be optimized for one or two sleepers. The mattress topper is available in Me and We, Queen, King, and Cal King sizes. “Me” sizes are designed for one sleeper (one control unit) and cover half of the mattress; “We” sizes are designed for two sleepers (two control units) and cover the entire mattress. Even better, if you purchase the WE unit, you and your partner get two control units so that you can each find your ideal sleep temperature, night after night.

Can my environment effect the peak performance of the sleep system?

Peak performance is dependent on multiple factors such as ambient temperature, individual body mass and humidity and may not be suitable to replace conventional A/C.

How often should I clean the Cube control unit?

We recommend cleaning the system once per month by adding one packet of ChiliSleep System Cleaner to your Cube reservoir and fill with distilled water. To keep your system in top shape, follow these helpful cleaning tips.

How do I wash the Chilipad®?

We recommend a front-loading washer (or a top loader without an agitator). Secure the pad tubes with a thick rubber band, rope, etc. Wash with cold water on a delicate cycle.

To dry the pad, keep the pad tubes secured and dry on a delicate cycle with no heat. Do not bleach, do not iron, and do not dry-clean the pad.

Make sure the pad is completely dry before reconnecting to a power source.

What is your shipping and return policy?

  • Fast and free standard shipping and returns. Will be shipped in 1-2 business days.

  • 30-night sleep trial (full refund included)

  • 1-year warranty

  • Straightforward and easy assembly and maintenance instructions

Will a WE sleep system work with an adjustable bed?

We recommend two ME Sleep Systems rather than one WE Sleep System for Split Adjustable Beds. Because both sides adjust independently, placing two ME pads on the mattress will allow each side to adjust without damage to the pad or restricting the adjustable positions.

Additionally, we advise installing ME pads placed on adjustable beds with the connection hoses at the foot of the bed. After installation and during use, make sure that the hose remains loose (not taut) and free from crimping between the mattress and bed frame, which can damage the hose.
