With SensorSafe

The CYBEX Eternis S with SensorSafe™ is the only seat your child will need from birth and beyond. With three modes - rear-facing, forward-facing, and booster, this All-In-One Convertible Car Seat is designed for use from birth up to 120 lbs. The Eternis S with SensorSafe features Linear Side-impact Protection, and a patented 3-position reclining headrest that guides the child’s head and neck into a proper position while they are asleep. With SensorSafe™ technology, you'll gain instant insight into your child's well-being—right to the SensorSafe app on your phone. Built into the chest clip of CYBEX car seats, SensorSafe provides alerts when unsafe situations arise including if a child unbuckles themselves; if the back seat has become too warm or too cold if a child has been seated for too long, and if the driver accidentally leaves the child behind.

 

Specifications 
  • Rear-facing from 4 lbs. to 50 lbs. Forward-facing from 22 lbs. to 65 lbs., Belt-positioning Booster from 40 lbs. to 120 lbs.
  • SensorSafetechnology uses a Bluetooth-enabled chest clip to send mobile app alerts when potential unsafe situations arise (not used in Belt-positioning Booster mode).
  • Linear Side-impact Protection absorbs up to 25% more impact forces in a collision (when compared to the same car seat without L.S.P. extended).
  • Patented 3-position reclining headrest helps prevent the child's head from falling forward while asleep, keeping the head and neck in a proper position.
  • In-seat recline provides correct ergonomic positioning and extra legroom, allowing your child to ride rear-facing longer.
  • 12-position, height-adjustable headrest with a no-rethread harness.
  • 6-position one-hand adjustable recline for the best fit to your car.
  • Magnetic buckle holders for easy entry and exit from the seat.
  • Removable newborn insert provides support from 4 to 11 lbs.
  • Dishwasher-safe cup holder can be positioned on either side.
  • Harness pads and 2-position padded buckle.
  • Steel reinforced frame provides strength and durability.
  • Energy-absorbing shell and base help reduce the forces felt by the child in a collision.
  • Dual-level indicators to help ensure the proper angle.
  • Innovative one-pull LATCH removal system.
  • LATCH Connection storage provided under the seat when not in use.
  • Designed and engineered in Germany.

Time release.. ONLY way to go
Used this brand before... when refill needed, came back for more. Time release is the best way to go as it works all night. Not one big hit when you 1st go to sleep... A nice "hit"... to get you to sleep and then a slow release of the rest, to KEEP you asleep... Don't think you'll be disappointed. I use sustained release with any vitamin/supplement I take (assuming the company makes it) .. including this. It's the best way to allow your body to utilize the product.

A subtle sleep enhancer.
Melatonin, in my experience, is a very subtle drug. I took it for about a month and then stopped before I actually saw what it was doing. It allowed me to fall asleep quicker and when I woke up during the night, to fall back asleep quicker as well. No more tossing and turning. I prefer the timed release version since I tend to sleep about 4-5 hours straight and then wake up sporadically after that. I had been buying the timed release from GNC but this brand is much cheaper, more pills, and just as effective. I've also tried popping another one after that initial 4-5 stretch of sleep to further prolong sleepy time, but I don't know how effective that is. It doesn't put you to sleep, so there's no grogginess when you wake up. It just jump starts the natural process.

Time release is the best way
I like these time released tablets. Time release is surprisingly hard to find unlike the immediate release style tablets. Time release allows for a longer sleep pattern as it enters the blood stream slowly over time allowing it to stay in you system. Immediate release will hit you hard and fast but your body will metabolize within a couple of hrs leaving you without the melatonin in you system. I took off a star for being pricey, but these do work very well.
