Pick the Eight Sleep Pod 5 if you want a bed that tracks your sleep and adjusts itself, and a yearly membership doesn't bother you. Pick the Chilipad 2.0 if you simply want a cold (or warm) bed, separate sides for a couple, and no ongoing fee.
- Both run cooled or warmed water through a layer on top of your existing mattress.
- Eight Sleep's autopilot, sleep reports and smart alarms need a paid membership, required for the first year; we estimate $200 to $400 a year.
- Chilipad 2.0 has no subscription; cooling, heating and scheduling are free.
- Approximate prices as of mid-2026: Chilipad 2.0 from $1,599 for one side; Pod 5 from around $2,900 for a queen.
- Chilipad 2.0 includes a remote, a 2-year warranty and a 30-night trial, and is HSA/FSA eligible.

On this page11 sections
It's 3 a.m. and you've kicked the blanket off, flipped the pillow to the cold side and peeled a damp sheet off your skin. Twenty minutes later you're cold and doing it all in reverse. If that's you, or the person next to you, you already know a fan and cooling sheets don't fix it. The heat is trapped under your body, in the mattress, which is the one place a fan never reaches.
Bed cooling systems go after that heat directly. Here we compare the most talked-about one, the Eight Sleep Pod 5, with the new Chilipad 2.0 by Sleepme. We've slept on both. Chilipad sponsored the video this is based on and asked for an honest side-by-side rather than a sales pitch, so we give the Pod 5 full credit where it's earned. We only have an affiliate link for Chilipad.
Quick verdict
For most hot sleepers and couples who disagree on temperature, the Chilipad 2.0 is the better buy: strong, steady cooling, independent sides, a bedside remote and no subscription, for far less over five years. The Eight Sleep Pod 5 is the more sophisticated machine and the right pick for data-minded buyers who want automatic adjustments and built-in sleep tracking and don't mind paying every year.
Why bed temperature matters
As you drift off, your core temperature naturally drops by a degree or two, and that dip is part of the signal that tells your brain it's time to sleep. When the bed traps heat, your body fights that dip all night, so you skim along in light, restless sleep instead of reaching the deep stage. Cooler nights may help you spend more time in deep sleep, when a lot of physical recovery happens. A gentle warm-up in the morning works the other way, easing you awake instead of yanking you out of a dream.
A cooled sleep surface won't fix every sleep problem, but for many hot sleepers it's the difference that matters.
What they have in common
The Pod 5 and the Chilipad 2.0 chase the same goal in the same basic way: water. Water moves heat far more effectively than air. Both systems pump cooled or warmed water through a layer that sits on top of your mattress, pulling heat off your body or feeding warmth back in. You keep your own mattress; nothing gets thrown out or replaced.
Both can also cool the two sides of a bed independently, so a hot sleeper and a cold sleeper can share. From there, the two split hard.
Eight Sleep Pod 5: the most advanced option
The Pod 5 is the most advanced system in this category, with no asterisk. It circulates water through a cover that grips your mattress like a fitted sheet, and it does two clever things at once.
- Sleep tracking without a wearable. No ring, no watch. It reads your heart rate and breathing through the cover.
- Autopilot. It uses that data to adjust your temperature up and down through the night on its own, following your sleep stages.
For couples, a single hub cools both halves of the bed independently, so if you run hot and your partner wears socks in July, you each get your own zone from one unit. On a still night we found it close to silent. That automation is the kind of thing that spoils you.
The catch is the membership. Autopilot, sleep reports and smart alarms all sit behind a paid plan, which is required for the first year. You can cancel after that, but the moment you do, the Pod loses nearly everything that made it special and drops back to manual control. It still cools and heats; you're just no longer getting what you paid the premium for. Over five years, by our estimate, the fee adds somewhere between $1,000 and $2,000 on top of the hardware. And if you already wear a sleep tracker such as an Oura Ring, Whoop, Apple Watch or Garmin, you'd be paying for tracking twice.
One more practical point, per Sleepme's comparison in the video: the Eight Sleep topper can't be washed, whereas the Chilipad's cover can.
Chilipad 2.0: simpler, and better than we expected
We went in expecting the Chilipad 2.0 to feel like the cut-price option. It didn't. On the first night the surface chilled within a few minutes and held there all night, with no fading and no warm patches creeping back around 4 a.m. We stopped the blanket dance and just slept. That steady temperature is what you actually feel, and it gets lost in spec comparisons.
Sleepme has been making these for over 10 years, and the 2.0 reads like a list of fixed customer complaints:
- Rebuilt cover. The water layer, which Sleepme calls the Hydro Layer, slides into one side or both. The cover is far easier to wash and has a mattress protector built into the base, so that's one less thing to buy.
- Fits more beds, including full, twin XL and split adjustable bases.
- Modular. Start with one side of the bed at roughly half the cost and add a second Hydro Layer later.
- Quieter dock. Close to a whisper, it tucks under most beds. The reservoir is easy to top up, needs refilling less often, and the digital display flips so you can read it from bed.
- A remote in every box. It sits on your nightstand like a thermostat for your bed, so you can change the temperature half asleep without finding your phone. It can sense when you're in bed and start your schedule.
- An app for weekly schedules, each partner's side and a gentle warm wake-up. It works with Google Assistant and offers open APIs.
The headline: no subscription. Cooling, heating and scheduling across the week are free for good, with no paywall in front of the features. The 2.0 also ships with a 2-year warranty, up from one, and its design is repairable, so if a part wears out you replace that part rather than the whole system. The temperature range runs from 55 to 115°F.
What you don't get is the Pod 5's built-in sleep tracking and autopilot adjustments. If those are what you want, the Chilipad isn't trying to compete there.

Price and five-year cost
As of mid-2026, the Chilipad 2.0 started at $1,599 for one sleeper. That's the half-bed setup with the dock, the cover with the Hydro Layer and built-in mattress protector, and the remote, all in one box. Couples who want both sides step up to the two-zone version, which costs more. Included with that price: free shipping, a 30-night sleep trial, the 2-year warranty, HSA and FSA eligibility, and the option to pay monthly at 0%. You pay once, and there's no fee after that.
The Eight Sleep Pod 5 started at around $2,900 for a queen, passed $3,000 for a king, and the Ultra with the adjustable base sold for over $5,000. Then add the required membership, which we put at roughly $200 to $400 a year, every year you own it.
Run that out over five years and our estimate puts the two about $1,600 to $1,800 apart in the Chilipad's favour, before counting the fees you'd still be paying in year six and beyond. Put another way, what one Pod 5 costs you over five years could cover a Chilipad that cools both sides, with money left over.
Who should skip each one
Skip the Eight Sleep Pod 5 if you don't want a recurring bill for a bed you've already paid for, you already wear a sleep tracker, or you suspect you'll stop opening the sleep dashboard after a few months. Without the membership, you're paying a premium for manual control.
Skip the Chilipad 2.0 if what you want most is automatic, data-driven temperature changes and nightly sleep scores without wearing anything. Also note the 30-night trial is short, so set it up and test it properly in the first weeks.
Which to pick
- Get the Eight Sleep Pod 5 if you're a data person who wants a bed that reads your heart rate, scores your night and adjusts itself while you sleep, and the yearly fee genuinely doesn't bother you. You'll probably love living with it.
- Get the Chilipad 2.0 if you sleep hot, share a bed with someone whose thermostat is set to the opposite of yours, or live somewhere hot or without good air conditioning. It's also a sensible fit for parents, shift workers, and women dealing with temperature swings from their cycle, pregnancy, postpartum or menopause.
What would we do? We'd buy the Chilipad. We want the cold bed and the rested morning, not a sleep dashboard we'd stop checking by month three, and not a fee leaving our account for a bed we've already paid for. The Chilipad 2.0 does the one thing we want, does it well, and gets out of the way.
