Tranquilo Mat as Seen on Shark Tank


Tranquilo Mat calms babies by mimicking the sounds and motions of the womb.

While in utero, your baby is suspended in amniotic fluid and gently swayed and jostled from every shift in your body position, as well as lulled by constant motion and sounds from your heart beats, blood flow, and other bodily functions.

The sounds inside the womb have been recorded as high as 80-90 decibels —nearly as loud as a vacuum cleaner or hairdryer!

After emerging from nine months in a warm cocoon of constant motion and white noise, it’s no wonder new babies often “cry for no reason.”

Through his work with newborns, pediatrician Dr. Harvey Karp found that most fussy babies are soothed by harnessing the calming reflex through shushing and constant motion reminiscent of the womb. But driving around the block, endlessly bouncing up and down, and other soothing techniques are exhausting for already overwhelmed and sleep-deprived parents.

Tranquilo gives worn out parents a break! Designed by a maternity nurse with over six years experience caring for thousands of infants, Tranquilo Mat provides your crying baby with the reassurance of the womb by combining the comfort of vibrations with white noise.

Tranquilo’s lightweight vibrating baby mat rolls up to the size of a newspaper and goes wherever baby goes! Take it with you anywhere—grocery store, library, gym, daycare, the beach,  softball games. Worried about your crying baby irritating other passengers on your next flight? Tranquilo can help!

Different babies have preferences for sounds, vibration strengths, and levels of white noise—preferences that may surprise you and differ from your own. Whether your crying newborn has colic or your baby simply won’t stop crying, we’ve got options! Choose from five different vibration modes including whooshing and heartbeats sounds. A 60-minute shut-off setting is also available.

Easy to clean

Interior electronic components are fully protected from diaper leaks and spit up. To clean,  simply toss the 100% cotton cover in with the rest of your laundry and wipe off the waterproof interior liner with a damp cloth. Coming soon: 100% organic cotton replacement covers in adorable prints so you can keep using your mat while the other cover is in the wash!


Tranquilo has carefully sought out, tested, and selected only phthalate-free, BPA-free, and lead-free components including all parts encased in the waterproof barrier. Tranquilo Mats have been tested by a third party laboratory in the U.S. Common sense safety considerations are included in our labeling and use instructions.

A word on Battery Life 🙂

Batteries last up to two weeks with regular use and over a month with more intermittent use. In total, you can get approximately 24-48 hours of continuous use from your Tranquilo vibrating mat with one set of batteries. Inexpensive store brand batteries don’t last nearly as long as high quality name-brand batteries. To save battery use, we recommend using the 60-minute auto-off function (activated by pressing and holding the ON button for 5 seconds instead of the standard 3 seconds). This feature allows the mat to work in calming baby whilst still conserving batteries. For the eco-friendly and budget savvy folks, we recommend investing in some rechargeable AA-batteries to use with your Tranquilo Mat.

Please note that if your mat turns on but then turns off when you try to change the mode, that’s a sign that the batteries need to be changed. Additionally, in rare cases, if the mat is turned on but the low mode doesn’t work until all modes have been cycled through, this is a sign that the batteries are low and should be changed.

And stay tuned as we are working hard to develop a safe, rechargeable and eco-friendly alternative while still maintaining the ultimate in portability!

Can I leave my baby alone (or overnight) with the mat running?

Tranquilo Mat was designed to be a safe and portable baby-soothing option, not an overnight white noise machine. In addition, the mat adds extra material to cribs so we wouldn’t advise leaving your baby alone with the mat for an extended period of time.

If you wish to use the mat to help baby sleep, we recommend opting for the 60-minute shut-off function, which also helps preserve batteries. Please note our battery life information above.

After reading all of the instructions and warnings and accepting full responsibility for how you choose to use the product, you are free to make any decision that works best for your child and family.
