This product will:


Recline to perfectly adjust to vehicle seat

Maintain a comfortable body temperature

Grow with your child by adjustable headrest

Reclining headrest keeps child's head within safety zone for protection in case of impact

Linear Side-impact Protection (L.S.P.): Adjustable side protectors absorb force of impact earlier and away from child

12-position adjustable headrest allows seat to grow with your child

Extra-wide and deep seat cushion with extra soft padding

The patented three-position headrest adjustment allows the child?s head to rest comfortably leaning backwards and thereby preventing the dangerous situation with the head tipping forward when they fall asleep. This not only is more comfortable for the child, it also keeps the head in the Safety Zone in the event of a side-impact crash.

The Linear Side-impact Protection (LSP) system with adjustable side protectors starts the absorption of energy in a side-impact earlier and together with the thick side wings helps dissipate the energy away from the child for ultimate protection.

The 12-position headrest adjustment allows the seat to grow with the child.

Installation is easy using the rigid LATCH system that connects to the vehicle?s lower anchors. This keeps the seat steady for easy climbing in and out of, as well as keeping it steady in a side-impact crash.

Padded armrests allows the child to sit comfortably and helps keeping the lap belt in a low and secure position. Built in ventilation system improves comfort on hot days.

5 kids, needed the perfect booster
November 10, 2016
We have 5 kids, ages 8 to newborn. We also have the Honda Odyssey so we have 3 in the middle and 2 in the back (you can't fit 3 booster seats in the back because they won't be able to buckle). We got this seat in pink and another one in blue for the back seat and they are PERFECT! When they fall asleep it keeps their head from falling down and they are really comfortable. Would definitely recommend them!

Functional & Comfort in a safe stylish combo

My son just heighten out of his 5pt harness at 8yrs old so I wanted the next safest and long lasting high back booster for him. He loves this!! The head tilt keeps his head and neck safely within the head cushions when he falls asleep. It never tips forward. The extra impact was easy to activate on the side making me feel even better. The seat belt lines up nicely and is never in the wrong location on his body. The rigid latch keeps the seat from skidding around which makes us both feel more secure!! The only thing I wish it had was something to keep him from submarine get but I haven't seen any other boosters that do. I'm so happy I made this purchase!!
  • Rigid latch
  • Head tilt
  • Comfort

Leaps and bounds better than any other booster seat
September 3, 2015
I have an 8-year-old that had been using a backless booster seat for several months. One night, we were traveling home from visiting family, and she fell asleep. When I looked back, her neck was flopped over sideways, and I remember thinking how dangerous it would have been if we'd gotten in a car accident with her like that. I recently bought the Cybex Aton Q infant seat for our younger child, and I began browsing the Cybex booster seats. When I saw this one and how much protection it offers older children, I felt like I had been extremely negligent to let her ride around in a car without head/neck protection. This booster seat is fantastic. My daughter *loves* it. She says it's very comfortable, and she loves that the headrest reclines, so she can nap comfortably on trips. I love that the torso area is adjustable, so you can literally customize it to your child as they grow.
