Sleep Better With The Smart Topper
Your body temperature changes while you sleep. Why shouldn't your bed? The Smart Topper is a specialized 2 inch layer that sits on top of your mattress. It has built-in sensors that automatically adjusts its temperature to keep you sleeping comfortably all night long.
The Smart Topper Really Works
The Smart Topper measures your body temperature and automatically adjusts air circulation underneath and around your body which keeps your body cool and dry all night long. It cools you when you need cooling or warms you when you need warming.
The Smart Topper keeps you dry. Water-based solutions like Eight Sleep and ChiliPad do not extract moisture from your bed to keep you dry.
The Perfectly Snug Smart Topper cools beneath you where you need it most. BedJet does not cool beneath you (where it's hottest).


No Water
The Smart Topper uses specially designed fans to create active airflow beneath your body to keep you and your bed cool and dry. Your sheets will feel like they're fresh out of the dryer!
Eight Sleep and Chilipad circulate water in your bed risking leaks, mold, mildew, and condensation.
No Beside Equipment Or Hoses
The Smart Topper is clutter free. There are no control units or hoses.
Eight Sleep, Chilipad, and BedJet have bulky control units with hoses that connect to your bed.

Active Airflow
The Smart Topper uses active airflow underneath your body to keep you and your bed cool and dry. This cool air flow under your body, prevents heat build up where you lay and carries away excess humidity reducing night sweating.

Dual zone controls allow for you and your partner to set personalized temperature settings on each side of the bed. No more fighting over the thermostat!
Moisture Removal
The gentle cooling airflow underneath and around your body ensues that you'll stay cool and dry throughout the night.


Smart Sensors
The sensors in the Smart Topper monitor your body temperature to detect when your body temperature has risen or fallen below your set temperature. When it detects the temperature change, it will automatically adjust cooling and heating throughout the night.
Schedule Your Sleep
Your sleep temperature changes throughout the night. Schedule your sleep temperature preferences so you can fall asleep quickly, sleep soundly, and wake up naturally.


Burst Mode
A burst of cooling or warming is perfect for rapid relief. Simply hold down the up or down button for an instant burst of warming or cooling.
Foot Warming
Hate getting into bed with icy cold feet? Turn on the foot heater and say goodbye to icy cold feet. Climb into a cozy warm bed with heating concentrated at the bottom of your bed.

What Sleep Reviewers Have To Say

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

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

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.
