From Cybex, this booster car seat features: The CYBEX Solution Z-Fix offers a high-back booster seat designed to grow up with your child, adapting to their changing needs. This seat boosts standard safety features by offering a patented, reclining headrest that guides your child's head into a safe and comfortable position, and an optimized Linear Side-impact Protection system to ensure the highest level of safety and comfort for your child. Using just one hand you can adjust both the height and width of the booster seat in one motion to ensure a proper fit to your child's size. Suitable for a child 4 years and older Internationally Patented 3-Position Reclining headrest - The CYBEX internationally patented reclining headrest helps protect the child's neck and head in the case of a side impact by safely shifting the balance point of the child's head slightly back and preventing it from falling forward. Furthermore, our 3-position headrest guides your child's head into a more comfortable position Automatic height and width adjustment - With one hand, simultaneously adjust the height and width of the seat back into 12 different positions to ensure the proper fit for your growing child Linear Side-impact Protection (L.S.P) - Linear Side Impact Protection is a feature of CYBEX car seats that absorbs impact forces of certain side-impact crashes and directs these forces into the energy-absorbing shell of the car seat and away from the child's sensitive neck area. By extending the L.S.P. system on the side of your car seat facing the door, this feature takes the initial brunt of the force and helps keep your child safer in the event of a near side impact. Car seats with L.S.P. extended see a reduction in near side-impact forces on the baby by up to 25 % when compared to the same car seat without L.S.P. The air ventilation system provides a comfortable seating temperature even on hot days Rigid LATCH connectors properly position the booster in the vehicle with one-click installation Fabrics machine washable cold, delicate cycle, with a mild detergent Dimensions: 16" L x 21-23" W x 24.5-32.5" H Weight: 15.9 lbs.
