As part of the CYBEX Gold Car Seat line, this versatile seat combines ease of use with cutting-edge safety features, designed to protect your child from their first ride and through every stage.

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.

Not durable
I love the initial fit and feel of this bra. Its very comfortable and silky. I was disappointed to discover the poor design which allows the underwire to poke through much too quickly. It happened on both of my bras from this company. I bought 2 hoping the first was just defective but the second had the same issue in the same area.

Great coverage for a chesty gal with smaller band size
Size: 34F, Color: Gentle Rose
I don’t know why I can find bras that fit better on Amazon than in store, but this one is a good one. It fits well and is as comfy as you can expect from an underwire. It has zero lining and that can be an issue, so pay attention to that if it is important to you for the nip coverage!

Did not last long
Size: 44E, Color: Black
I really like this bra very much, it was very comfortable and fit well, but the wire popped out of the fabric in less than a couple of months. Very frustrating.

Good bra but doesn't last long
Size: 40H, Color: Brown Purple
Love these bras...BUT...after just a few short months they have broken. I bought a bunch of these at first because they are very comfy and fit well. However, I now only have 2 left because the underside has broken on all the rest. It has snapped on 2 of them and 3 other it has popped through the lining. I'll have to find something else.
