If you want to dip your toes into bed cooler world without breaking the bank, Adamson might be your best bet.

This water-cooled unit requires more upkeep in the form of filling and changing the water.

However, it offers a cooler sleeping environment at a fraction of the cost of 8sleep.

This one’s worth checking out and potentially returning if it doesn’t work out.

4. Sleepme Ooler

This water circulation model offers strong cooling power and quiet operation.

Users love the consistent temperature it maintains all night.

The product has good scheduling options and requires cleaning every 3-6 months.

Used Bed Cooler

Source: Ebay

You can sometimes find used units on eBay for around $200-300 and pair them with inexpensive medical cooling pads.

With some hunting, this gives you close to high-end cooling performance at a budget price.

The downside is that you will need to set up alerts on eBay or constantly refresh the search page.

How Bed Cooling Devices Work

Bed cooling devices use different technologies to lower the temperature around your body while you sleep.

Here are details on how the main types work:

Circulating Water Method

Devices like the ChiliPad and Ooler rely on circulating cool water to pull heat away from your body.

They consist of:

  • A control unit with a water reservoir and chiller that cools the water.
  • Pads or tubes filled with the chilled water. These go under your sheets and conform to your body.
  • Hoses to circulate the water between the control unit and the pads/tubes.

The chilled water in the pads absorbs your body heat.

As the water warms, it gets recirculated back to the control unit, where it’s cooled again.

This creates a constant flow of chilled water to maintain your chosen temperature all night long.

Some key advantages of the circulating water method:

  • Provides uniform cooling over large areas. The pads mold to your shape
  • Operates quietly, only the soft hum of the chiller
  • Temperature stays steady through the night

Potential disadvantages include possible leaks from the pads or hoses over time.

And keeping the water clean to prevent mold buildup.

Air Cooling Method

The forced air method uses a blower to direct air under your sheets.

Popular models like the BedJet work this way.

The main components are:

  • A control unit that houses a fan/blower and air temperature control.
  • A hose that attaches to a vent is placed under your sheets.

The blower forces air out of the vent into your bed.

Some units use room temperature air for gentle cooling breezes. More advanced models can actively cool the air before blowing it.

Benefits of forced air devices:

  • The cooling effect starts quickly once turned on
  • No water to leak or maintain
  • Units tend to be more compact

Potential negatives are noise from the airflow.

And cooling may not be evenly distributed – more focused on areas closest to the vent.

So, in summary, circulating water keeps the whole bed at an even cool temp.

While forced air provides quicker, more localized cooling.

Bed Cooler Benefits

Bed Cooler Mattress Benefits

So, why go to the trouble of getting a cooling device for your bed?

Let’s take a look at the real benefits for your sleep quality and health.

Sleep Deeper

Being too warm in bed can lead to tossing and turning, frequent wakeups, and lighter, disrupted sleep.

By keeping your optimal temperature of around 65°F, bed coolers allow you to fall into deeper, more restorative sleep stages.

Wake Up Refreshed

Waking up overheated and sweaty leaves you feeling groggy and tired.

Cooler sleep lets you wake up feeling recharged and ready to take on the day.

This is a small investment toward having a more productive day at work or school.

Lower Sleeping Heart Rate

Studies show cooler bedroom temperatures lower your heart rate as you sleep.

A lower resting heart rate is associated with higher sleep quality.

Reduce Insomnia

Many people have trouble initially falling asleep or get night sweats that disrupt sleep.

The right temperature improves sleep onset and continuity.

A mattress cooler is a small investment before turning to prescription medications or OOC drugs.

Ideal for Hot Sleepers

Genetics can play a big role in how you experience temperatures at night and during the day.

If you run hot when you sleep, bed cooling provides relief without freezing your whole room.

This is also perfect for partners with different temperature preferences.

May Ease Anxiety

Some evidence shows cooler sleep environments can reduce anxiety, likely by lowering heart rate and preventing night sweats.

There is also a vicious cycle when it comes to sleep stress.

You stay up all night worrying about not getting enough sleep, which leads to poor sleep the following night and so on.

Key Features to Compare

When shopping for a bed cooler, there are several key features to evaluate:

Cooling Power

Check the temperature range the cooling device can achieve.

Can it get down to your desired sleeping temperature and maintain that temperature throughout the night?

More powerful units have larger chillers and water reservoirs.

Noise Level

This is critical if you or your partner are light sleepers.

The hum of the chiller unit and water circulation pump can be distracting.

Air-blown models tend to be louder than water circulation options.

Look for decibel ratings and consumer reviews.

Size Options

Bed coolers come in sizes for twin, full, queen, king, and more.

Measure your mattress and get the right fit.

Some coolers can even be configured for two control units on extra-large beds.

Programmable Options

Preset cooling schedules or modes are convenient.

Look for models with app control and integration with smart home systems.

Features like gradual wake-up warming, temperature auto-regulation, and sleep-tracking data may be desirable.

Maintenance Needs

Most bed coolers require periodic cleaning and maintenance, especially water-based models.

Check how often you need to change filters, add cleaning solutions to the water like hydrogen peroxide, and inspect for leaks.

DIY Cooling Options

Before investing in a bed cooling system, some simple DIY ideas to test cooling yourself include:

Frozen Ice Packs

Freeze reusable ice packs and place them under your sheets near hot spots.

This can provide temporary cooling for a few hours before re-freezing.

However, you might run into issues with wetness from condensation.

Pet Cooling Pads

Get a basic pet cooling mat or pad and place it in the fridge/freezer before bed.

These are larger than typical cooling packs; you can pick a bigger size for better bed coverage.


Use a small fan in the bedroom focused on exposed body parts like feet.

This will provide targeted airflow and evaporative cooling.

It’s not the best solution, but certainly cost-effective.

The Bottom Line

You don’t need to spend thousands on an 8sleep to get bed cooling.

Affordable alternatives from ChiliSleep and BedJet offer similar functionality at a fraction of the price.

And DIY options can give cooling a test run.

We hope you find the right bed cooler to fit your budget and needs.

And finally, get that blissful, uninterrupted sleep. No AC required!


What are the downsides to bed coolers?

The main downsides appear to be:

  • Require regular cleaning and maintenance
  • Water circulation models can spring leaks
  • It may not get as cold as advertised
  • Some noise from the cooling unit
  • Bulkier devices may not fit under all beds

So, there are some tradeoffs compared to the premium options.

However, users report reliable cooling, especially with models from Ooler and BedJet.

How do these bed coolers compare to the 8sleep?

The 8sleep chiller starts at over $2,000 and requires a $15-24 monthly subscription for additional features.

The alternatives above offer similar cooling at a fraction of the price without any subscription.

They lack some “nice-to-have” features like automatically warming up the bed in the morning.

But overall, they provide excellent cooling according to users.
