Best bed cooling systems for 2026, ranked

Key takeaways

• The Orion Sleep System heats and cools each side separately. Its range is 50°F to 113°F, it fits over the mattress you have now, and its heating and cooling need no subscription.

• Eight Sleep’s Pod 6 has similar functionality to Orion with a higher price tag. It comes in Full and Twin as well as the larger sizes and tracks sleep through the cover, but Autopilot is required for the first 12 months, and the Pod costs more than Orion at every size both sell.

• Water moves more heat than air. Orion, Eight Sleep and Sleepme pump chilled or warmed water through a cover on the bed. BedJet and Perfectly Snug blow air, which is cheaper but can only cool as far as the air in your room allows.

• Count the yearly cost as well as the sticker price. Two of these five charge for a membership, and one makes it a condition of purchase.

• Couples need true dual-zone control. Every pick here can run two sides at two temperatures, but some need a second unit to do it.

How bed cooling systems work, and how we ranked them

A bed cooling system changes the temperature of the surface you sleep on, not the room. Most use a thin cover or pad on top of the mattress and a unit beside the bed that either circulates temperature-controlled water through the cover or blows air under the sheets. Nearly all of them heat too, so the same system warms the bed in winter.

They’re for people who wake up hot even with the room cool and the sheets light, and for couples who can’t agree on a temperature. A cool bedroom only does so much, because the air trapped under your covers counts for more than the room, as we explain in what’s the best temperature to sleep at.

We ranked these five on temperature range, whether each side of the bed can be set on its own, whether it works on the mattress you already have, what it costs to buy, what it costs to keep running each year, and the trial and warranty. Prices are list prices from each brand’s site on October 25, 2026, before any sale.

1. Orion Sleep System - Water cooling with no required membership

The Orion Sleep System is a water-based heating and cooling cover that goes over your existing mattress. The Smart Cover fits over the mattress like a fitted sheet, under your own sheets, and a Control Tower beside the bed heats or cools water and circulates it through the cover. Each side can be set separately, anywhere from 50°F to 113°F.

Most of what it does works without paying again. Heating, cooling, two-sided control, schedules and the app are all included, with no subscription. Orion Intelligence, the sleep-tracking layer (sleep stages, heart rate and recommendations), is an optional $250 a year, and cancelling it leaves the heating and cooling untouched.

It comes in Queen, King and California King, and fits a standard bed or a single adjustable base kept nearly flat. It doesn’t come in Full or Twin, and it doesn’t fit a split king. List prices are $2,395 for a Queen, $2,595 for a King and $2,695 for a California King. It has a 30-night trial, a two-year warranty and free shipping, and it’s HSA and FSA eligible. Its design has won an iF Design Award and a Red Dot Award.

What works: Heats and cools each side separately across a 50°F to 113°F range, with temperature control included in the price.

What doesn’t: Only three sizes, so Full, Twin and split king beds are out, and the cover is spot clean only.

Best for: Couples who sleep at different temperatures and want to keep their current mattress without a yearly fee.

2. Eight Sleep Pod 6 - Sleep tracking built into the cover

The Pod 6, released in September 2026, is Eight Sleep’s latest water-based system. A cover goes on the mattress and a hub sits under the bed or beside it. Each side can be set from 55°F to 110°F, and the cover tracks sleep and heart rate. It comes in Full, Queen, King and California King, plus single-zone Solo versions down to Twin.

The catch is the membership. Autopilot, which runs the Pod’s automatic temperature changes, schedules, alarms and sleep reports, is required for the first 12 months and costs $199 to $399 a year depending on the tier. After a year you can cancel it, but the Pod then works only as a manual dial for each side. Eight Sleep’s warranty also depends on keeping an active membership: two years on the $199 plan, five years on the $299 and $399 plans.

It also costs more than Orion. The Pod 6 lists at $2,899 for a Queen and $2,999 for a King, about $500 more than Orion at Queen size and about $400 more at King. With the required first year of Autopilot, a Queen comes to at least $3,098. An optional Base that lifts your head and feet costs $1,999 more. There’s a 30-night trial with a full refund of the Pod and membership.

What works: Full and Twin sizes that Orion doesn’t make, and sleep tracking built into the cover.

What doesn’t: A year of Autopilot is required, it costs more than Orion at every size both sell, and much of the Pod’s function depends on keeping the membership.

Best for: People who want detailed sleep data and are willing to pay for a membership to get it.

3. Chilipad 2.0 by Sleepme - Water cooling you can buy one side at a time

Sleepme’s Chilipad 2.0, launched in May 2026, is a water-based pad that’s zipped inside a zip-off, machine-washable cover on the mattress, connected to a dock beside the bed. It runs from 55°F to 115°F and comes with a bedside remote as well as an app.

Each dock runs one zone, so a couple needs two. That makes it flexible: one person can buy their half (from $1,699 for half a Queen) and add the other side later. A full two-sided Queen costs $2,998, and a King $3,198. Its basic functions don’t need a membership, and it works without Wi-Fi. It has a 30-night trial and a two-year warranty, and it’s HSA and FSA eligible. It needs distilled water and an occasional cleaning cycle.

What works: A washable cover, a split king option and the choice to cool only one side of the bed.

What doesn’t: Two docks beside the bed for a couple, and a two-sided setup costs more than Orion or Eight Sleep.

Best for: One hot sleeper who shares a bed with someone who’s comfortable as they are.

4. BedJet 3 - Air cooling at a lower price

BedJet cools with air. A bedside unit sends a stream of air under your sheet, which cools by moving room air across your body or warms it with a built-in heater. Nothing with wires or water goes in the bed. BedJet lists the range as 66°F to 109°F, and says the low end depends on how warm the room is; it isn’t a substitute for air conditioning in a hot room.

A single unit lists at $699. The dual-zone kit for couples, with two smaller units and a sheet that splits the airflow between two sides, lists at $1,549 for a Queen. It has an app, and a remote works without a phone. BedJet has a 60-day trial and a two-year warranty.

What works: At $699 for one unit, it costs far less than the water systems, it heats as well as cools, and the trial runs 60 days.

What doesn’t: Air can only cool as far as the room allows, and a hose runs from the unit to the bed.

Best for: Cold sleepers, and hot sleepers in air-conditioned rooms who want something cheaper than a water system.

5. Perfectly Snug Smart Topper - Air cooling with nothing beside the bed

The Perfectly Snug Smart Topper is a 2-inch mattress topper with fans built into the foot end, so there’s no unit on the floor and no hose. The fans pull in room air to cool and the topper has heating built in. You set it through touch buttons under the sheet or an app, on 20 levels rather than a temperature in degrees.

Queen, King and California King toppers are dual-zone. A Queen costs $2,195 and a King $2,395. There aren’t any app subscription fees. It has a 30-night guarantee and a one-year warranty. At its highest cooling setting, the company says it sounds like a standalone fan.

What works: No unit beside the bed, no water to manage and no subscription.

What doesn’t: Like any air system, it can’t cool below room temperature, and the warranty is half as long as the others’.

Best for: People who don’t have room beside the bed for a tower or dock.

The five systems side by side

How to choose a bed cooling system

• Decide between water and air first. Water systems can bring the bed surface well below room temperature. Air systems cost less but can only cool with the air you already have, so they work best in a cool or air-conditioned room.

• Add up the first year, then every year after. Take the list price, add any required membership, and check what still works if you stop paying.

• Check the size and the base. Not every system comes in Full, Twin or split king, and some don’t work on an adjustable base that bends in the middle.

• Look at what sits beside the bed. Water systems need a tower, hub or dock on the floor with a hose to the bed, and couples on Sleepme need two.

• Use the trial. Give it a couple of weeks of real nights before you decide, and keep the packaging until you’re sure.

Frequently asked questions

Do bed cooling systems actually work?

Yes, in the sense that they change the temperature of your sleeping surface. Water systems like Orion, Eight Sleep and Sleepme can cool the bed below room temperature. Air systems like BedJet and Perfectly Snug cool by moving room air, so the result depends on how warm the room is.

Is there a bed cooling system without a subscription?

Yes. Orion’s heating and cooling need no subscription, with its sleep tracking available as an optional $250 a year, and Sleepme, BedJet and Perfectly Snug don’t charge a membership for their basic functions. Eight Sleep requires its Autopilot membership for the first 12 months.

How much does a bed cooling system cost?

At list price, from $699 for a single BedJet to $3,198 for a two-sided Sleepme Chilipad 2.0 in King. Two-sided water systems in Queen run from $2,395 for Orion to $2,899 for Eight Sleep and $2,998 for Sleepme. Membership fees, where there are any, come on top.

Which bed cooling system is best for couples?

Look for one that sets each side independently from a single system. Orion and Eight Sleep both do this with one unit. Sleepme and BedJet need two units for two sides, and Perfectly Snug does it in Queen sizes and up.

Do you need a new mattress for a bed cooling system?

No. All five go on top of the mattress you already have, as a cover, pad, topper or sheet. Check the size range and whether the system works with an adjustable base before you buy.

Are water or air bed cooling systems better?

Water systems cool further, because water carries heat away far better than air does. Air systems cost less and keep water off the bed. If your bedroom gets hot in summer, a water system like Orion, Eight Sleep or Sleepme is the safer choice.
