What Is SensorSafe?

The SensorSafe 2.0 chest clip monitors your child’s well-being, sending timely alerts directly to the caregiver’s smartphone if unsafe conditions arise. Originally developed to reduce incidents of children left unattended in vehicles, SensorSafe notifies caregivers if the car is switched off with a child still buckled, if the child unbuckles themselves mid-drive, if the back seat temperature reaches an uncomfortable level, or if a break is needed due to extended seating time. The alert system extends to emergency contacts with GPS coordinates if necessary, ensuring a continuous line of protection.

Good quality, works well.
Color: White, Size: Medium
Love it!! It took several hours and a brief air dryer time to get it fully fluffed up. It is perfect for my twin size bed. I found it very comfortable to sleep on although I would prefer it a bit more dense. Side sleeping, it flattens too easily. it comes with a carry bag but I had no use for it. Nice quality and soft cover.

Highly recommend getting this product.
Color: White, Size: Medium
Great pillow that is worth the money. We travel often as a family and got these and it was worth it. The quality is good and it it firm enough to be comfortable. I got good support and also enjoyed the fact that it can be rolled up into the travel pouch and transported.

If you want an afforable, adjustable pillow - give this a try
Color: White, Size: Medium
I live this pillow. I bought two one for travel and one for home. I'm a side sleeper and most pillows are too fat for me, but my old pillow finally got too flat. It is very light and has an interior pillowcasing with a zipper under the main pillow zipper. Open both and access/remove the shredded foam (?) stuffing material. Be sure to save it in case you removed to much, I ended up putting some back in. It is slightly curved on one long end. It find it very comfortable, and there is no smell from the filling. I'm sensitive to stuff like that. I took off one start, as I wish it came with a pillow case just that size. It fits in a regular pillowcase sort of. The long side of this small pillow fits in the short end of a regular pillow case, but then you have all that extra length hanging over it, I asked my mom to cut and sew a few down for me.

It was by far the best of the 3 I ordered
Color: White, Size: Medium, Color: White, Size: Medium
Good shredded memory foam pillow. Great for traveling. Great for side sleeper. I have had neck and shoulder problems and went through a ton of pillows before settling on Luxome Layr adjustable pillow. But way too hefty to travel with. I bought three travel pillows for a trip I am currently on - this one, a sleep number one and Alkamto travel and camp Pillow. The Alkamto was a no-go right away. Too squishy. Little support. Loved the Nappler. My husband liked it too so ordered him one. I will say his came in and was not as full as mine. I had some leftover fill from my Layr pillow so filled it out a bit for him. He doesn’t need one as supportive as mine so it wouldve be fine. It is nice because if it’s too firm you can pull some filler out. Had I gotten the second first it still would’ve been the best but I’m glad mine was fuller. The sleep number came in the next day and way good but not as good. Gave that to my adult daughter. Returned the Alkamto one as useless. The Nappler rolls up pretty easy and compacts down well in its bag so I could fit in my carry on. Was good for the flight - a long flight with lay down seats but crappy pillows. I’ve used it instead of the hotel pillows and also now the cruise ship pillows. 5 days into travel and I’ve very pleased.

Very comfortable/ Good support
Color: White, Size: Medium
I travel often and I’m always frustrated that I have to leave my good pillow at home. I bought this one very quickly and on a whim and boy was I surprised! I slept very well the first night with it! I didn’t have to make any adjustments to it at all! I like that it’s white and can go inside of any pillowcase. When you take it out of the dryer to initially fluff it, it looks very big, but is extremely comfortable and does not strain my neck at all! It provides excellent support.
