How does SafetoSleep work?

Simply place your baby on the mat and power it on. Next, launch the SafetoSleep smartphone application on your mobile device to pair it with the mat over Bluetooth. Once the pairing is successful, you will be able to monitor your baby from the app

Can I add additional layers of blankets, swaddling cloth, or fitted sheet between the mat and my baby?

Yes. However, we recommend keeping additional layers to 1 cm (.40 inches) or less.

How many devices can SafetoSleep talk to at a time?

SafetoSleep connects with one device at a time.

What is the range of the Bluetooth connection?

The range of the Bluetooth is about 100 feet. Do note that if your house is concrete or has interior masonry construction, the Bluetooth range might be be somewhat reduced.

I have twins on the way. Can I use two mats in the same house?

Yes, you can use more than one mat in the same house. Do note that each mat connects to only one device each time, so you will need two devices to take advantage of the monitoring function of two mats.

How much energy does the SafetoSleep mat emit and is it safe for my baby?

SafetoSleep products meet all U.S. and European standards for power emission. Unlike prevailing baby monitoring products, the optic fibre based technology used in SafetoSleep products does not emit electro-magnetic frequency (EMF) radiation and is 100% safe to use with babies and adults alike.

Where on the mat are the sensors located?

The sensor covers the entire surface of the mat.

What mobile devices are compatible with SafetoSleep products?

SafetoSleep products will work on any Apple or Android smartphone or tablet. The Bluetooth capability must be enabled and properly paired with the mat to receive alerts. At this moment, only Apple and Android devices are supported.

Is the Smartphone application free?

Yes, the app is free to download on the Apple App Store and Google Play

Is the SafetoSleep mat portable?

Yes. The mat is wireless and powered by 4 X AA batteries, so it’s easy to take with you.

How do I know if the batteries are low?


You may refer to the battery indicator on the LCD display panel of your STS200.


With typical 15-hour per day use, the batteries will last approximately 30 days. We recommend using lithium rechargeable batteries for best performance and environmental consideration, but alkaline batteries are compatible as well.

When my baby is sleeping on the SafetoSleep mat, the alarm goes on and off intermittently. Why is this so?

SafetoSleep is designed to alert you the moment your baby’s breathing patterns become irregular so you can take steps to check on your baby as soon as possible. In younger infants, slow or shallow breathing is very common and perfectly normal. The SafetoSleep mat is sensitive enough to detect these events and alerts you to check on your baby just in case.
