Why Perfectly Snug is the Best Sleep Cooling System

Perfectly Snug vs. Chilisleep

Compare the Smart Topper to the OOLER

The Smart Topper’s specially designed fans create active airflow beneath and around your body to keep you and your bed cool and dry. Your sheets will feel like they're fresh out of the dryer - all night!

OOLER circulates water in your bed. Water systems will eventually leak which can cause mold and mildew.

The Smart Topper is clutter free with no control units or hoses.

OOLER has a bulky control unit with hoses that connect to your bed creating extra clutter.

The Smart Topper keeps you cool AND dry. Air automatically circulates underneath and around your body as well as removes moisture. Stay cool and sweat-free all night long.

Our bodies produce sweat and moisture while we sleep. A water-based solution like OOLER does not remove moisture from your bed.

Perfectly Snug’s Smart Topper cools without creating heat, so there is no extra generation of heat being expelled into your bedroom.

Chilisleep's OOLER control unit uses a large amount of power to cool the water inside of it. This leads to the Hub expelling heat into your bedroom causing your room temperature to rise significantly.

The Smart Topper is maintenance free! 

OOLER's water-based system requires regular refilling with distilled water and a chemical cleaning agent like hydrogen peroxide.

With the Smart Topper, simply lay it on top of your mattress, plug into a wall outlet, and you’re ready to sleep cool!

OOLER set up is tedious, not to mention filling the bulky control unit with water and adding a solution to keep it fresh.

These Customers Tried Our Competitors - Here's What They Had To Say

I have tried the Chilipadand never liked how I could feel the tubing beneath me, but the Perfectly Snug topper is the right amount of firm and plush.

—Rhyz B.

I have used the water ones (too much maintenance), Sleep Number Dual Temp (annoying tubes on the side of the bed), and Bed Jet (the better of the rest), and found Perfectly Snug to be the best in its class.

—Mark M.

I have previously owned a ChiliPad. This is way better ! Easier to install, no maintenance, takes up no space next to the bed, and it works great.

—Katherine W.

What Sleep Reviewers Have To Say

gear diary 5 star review

If you’re concerned about the price, I get it. After using the Smart Topper for a couple of months, I’m now in a place where I can’t imagine not having one on my bed. If this review sample eventually dies, I’ll become a retail customer — that’s how much I love using the Perfectly Snug Smart Topper.

—Dan Cohen, Senior Editor and co-owner of Gear Diary

sleep authorities 5 star review

Bottom line… it is very effective at regulating the temperature of your bed over a sustained period of time.

Is the Perfectly Snug Smart Topper better than the Chillipad? Yes, The Smart Topper is better than the Chillipad. This is because the Chillipad features a bulkier, remote-controlled design, while The Smart Topper comes in the form of a mattress topper and is app-controlled.

Is the Perfectly Snug Smart Topper better than the BedJet? Yes, similarly to the Chillipad, the BedJet has a bulky design that isn’t as hidden or minimal as The Smart Topper. Plus, this mattress topper is also remote-controlled, rather than app-controlled.

Is the Perfectly Snug Smart Topper good for partners? Yes, this mattress topper is perfect for partners who have different preferences when it comes to the temperature of their sleeping environment. This is because of the dual-zone climate control feature, where each side can be set to different temperatures.

—Macie Maislin, Sleep Product Tester at Sleep Authorities

sleep sherpa 5 star review

There are all kinds of products out there right now that claim to keep you cool while you sleep but the Perfectly Snug Topper does it in the simplest way by circulating fresh air under your sheets. With this topper you no longer have to wake up sweaty and I found myself switching positions a lot less frequently at night. While it is a big investment, it is a solution that will keep you at an optimal temperature in a way no other technology on the market can.

—Ben Trapskin, Founder of The Sleep Sherpa


Size Guide

The Smart Topper does work on an articulated bed. We recommend using the included bed-corner straps to keep your Smart Topper in place.

Product Care

The Smart Topper is powered by low voltage DC power from a power brick that plugs into any standard wall outlet. The power supply will work in any country.

The cover of the Smart Topper can be washed. Learn more about washing details here.

Yes, the Smart Topper will automatically turn off. You can also set the on and off times with scheduled preferences in the app.

There are no safety issues if the Smart Topper gets wet. If it does get wet, it should be aired-out to dry to avoid developing mildew or mold.


The Smart Topper is nearly silent when cooling is at a low level. At 50% level of cooling it’s equivalent to a forced air household heating noise. At full cooling, it sounds similar to a stand-alone fan running in the room. The level of cooling selected will determine how loud the fans will run. If you're sensitive to sound, there is a quiet mode setting in the app that constrains the fans to run at a maximum of 50%.

We designed the Smart Topper to be thin enough to retain the comfort characteristics of your existing bed, however, those with a particularly soft bed will notice that the Smart Topper makes their bed somewhat firmer.

Shipping and Returns

We currently offer free shipping within North America on all Smart Topper orders.

Sleep on it for 30 nights risk free! If you don't love the Smart Topper within 30 nights, we'll take it back and refund you the purchase price.

When returned in original packaging, Perfectly Snug offers free return shipping.

Room Environment

The Smart Topper cools using room-temperature air, so, the cooler the room, the more effective the cooling effects will be. The Smart Topper is effective in a room of up to 82F/28C. If the room temperature is above this, the cooling is less effective as it will be pulling in hot air.

The Smart Topper can allow you to spend less on AC, by simply adjusting the temperature setting in your home by a couple degrees. It uses very little energy averaging 20 W to cool each side of the bed - about 2 cents per night!

Please note that the Smart Topper does not replace air conditioning or heating as it does not change the temperature of the room overall.


The Smart Topper is much more than a mattress! A mattress can't actively cool or regulate your temperature. Unique features like adaptive cooling and heating, smart sensors to monitor your temperature, and scheduled sleep settings requires specially developed technology and materials.

The Smart Topper is a high quality, North American made product that comes with a high level of service and care.

This includes any material or workmanship defect in your Smart Topper in the cover, foam, mesh material, or electronic defects in the sensors, wiring heaters, or fans.
