Ooler Review (Discontinued)

Sleepme (formerly ChiliSleep) stopped selling the Ooler in December 2023¹. Sleepme says the Ooler app is still supported and that it honored the one-year warranty within its period, so any Ooler bought new is now out of warranty¹. If you’re shopping now, see Best bed cooling systems or Eight Sleep Pod 6 vs Chilipad 2.0.

Last verified November 2, 2026. We rechecked this review against the brand’s current pages on that date. Prices, specs and model names below come from the sources linked in the references. Where we couldn’t confirm something, we say so.

What the Ooler was

The Ooler was a water-based bed cooling system. A bedside control unit cooled or warmed water and pumped it through a thin pad that went under your fitted sheet. It was controlled from a phone app over Bluetooth and replaced the remote-controlled original Chilipad. Sleepme’s current water systems are the Chilipad 2.0 and, while stock lasts, the Chilipad 1.0 (previously called the Dock Pro)².

What replaced it

Price checked November 2, 2026 on sleep.me unless the source says otherwise.

Model	Status	Starting price	Temperature range	Controls	Warranty
Ooler (this review)	Discontinued Dec 20231	$639 half queen, $1,119 queen (July 2022 listing)	Not in our 2022 notes	App	One year1
Chilipad 2.0	Current	$1,599 to $1,799 for one sleeper3; Queen dual zone $2,998, King $3,1984	55°F to 115°F3	Nightstand remote and app5	2 years, extendable to 35
Chilipad 1.0 (was Dock Pro)	Sold while stock lasts2	From $1,2995	See Sleepme’s comparison5	App5	One year5
Chilipad Cube	Current	From $6995	60°F to 115°F5	Remote only, no app5	See Sleepme’s comparison5

None of these has a subscription³. The main alternative is the Eight Sleep Pod 6, which adds sleep tracking but needs a paid plan for at least the first year⁶. Our comparison covers the trade-offs and three-year costs.

Joel’s experience with the Ooler

These notes come from Joel’s original first-hand review, published on MoveWell in 2023 (its prices date from July 2022). They describe a product that is no longer sold, and they are one person’s impressions, not measurements.

• Setup took him about 10 minutes: slide the pad onto the bed, put the fitted sheet back on and pair the app.
• The controller was smaller than the original Chilipad’s, but it needed about 6 inches of clearance on all sides, so with a low bed it sat beside the bed rather than under it.
• He found the app a clear step up from the original Chilipad’s remote: easier to set exact temperatures and schedules.
• In Austin, Texas, it seemed to need refilling less often than the Chilipad. He called this “a less exact science”; he didn’t measure it.
• It made a steady sound like a white-noise machine, louder in the rapid-cooling mode.
• Covering both sides of a bed needed two units, one per side.
• His summary at the time: “it’s tough to ever go back to sleeping on a regular mattress again.”

If you still own an Ooler

Sleepme says the app still works¹. The care steps below are how Joel looked after his unit; check your manual before you follow them.

• Cleaning: add one packet of Sleepme’s system cleaner to the unit, then choose “Start deep clean” in the app’s device settings. It took about 45 minutes. Drain and refill afterwards.
• Draining: unplug the tubes from the control unit, take the unit somewhere you can pour water, and insert the drain key.
• Washing the pad: secure the tubes, wash in a front-loading machine on cold and delicate, then dry on a no-heat delicate cycle. Make sure it is fully dry before you reconnect it.
• Repairs: the warranty has run out, so any repair is at your cost. Ask Sleepme before buying a used Ooler.

What the evidence says

A hot or humid bed makes sleep lighter and more broken; that part is well supported by sleep-lab studies⁷. Evidence that a powered cooling pad improves sleep more than a cooler bedroom is thin. The best direct study used a passive gel mattress, not a water system, and found about 7.5 more minutes of deep sleep a night⁸. For menopause hot flashes, the main cooling-pad study is a 15-woman pilot without a control group⁹, and The Menopause Society does not recommend cooling techniques for hot flashes¹⁰. Our bed cooling roundup grades each claim.

We removed claims from the earlier version of this review that cooler sleep “boosts metabolism”, “reduces overall stress” or improves glucose disposal, because it cited no studies for them.
