    • Safety is First with Booster Seat
Style: Skyline Color: Dusk
Granddaughter is 5-1/2 years old and we needed a booster car seat for our car. We don't transport her a lot so didn't want to pay a lot for a car seat. Of course we wanted one of high quality because its intent is for our precious one. We researched booster car seats and read reviews and chose this Britax Skyline booster. It arrived fast and we love the look of it with the black and red colors. The seat was easy to install, fits well in our car, and granddaughter says it's comfortable to ride in. Safety is key for us and the booster fits the bill. For a little over $100, we think we got a great deal on a quality booster seat. ... show more

    • Strong, Safe, and Built to Protect Young Padawans!
Style: Highpoint Color: Purple Ombre
The Britax Highpoint Belt-Positioning Booster Seat, a seat of great safety and strength it is. A wise choice, young Padawans and their guardians shall find. Much to love, there is: A range most impressive: From 40-120 lbs and 44-63 inches with the backrest, and 48-120 lbs and 46-63 inches without. Growth, this seat allows. The path of transition: A true 2-stage booster it is. Converts from a high back to a backless booster, so your youngling rides safer, longer. Yet, wisdom dictates the high back’s extra protection is the way to go. Cup holders, you seek? Yes, included they are! Hydration and convenience, a Jedi must always have. Comfortable, our youngling finds it. Long journeys, restful they remain. A removable and washable cover, it has. Messes, the dark side of parenting they are. But fear not, for this seat is prepared. Install and remove, with ease you shall. The safety latches? Strong they are, ensuring the seat stays in place when your youngling is not aboard. Stability in all situations, it provides. Layers of protection, mighty they are: 3 layers of side impact protection, an energy-absorbing shell, side cushions, and a quick-adjust headrest. Like the shields of a Jedi starfighter, they defend against harm. Three of these, we own. Happier, we could not be. For those seeking safety, durability, and peace of mind—trust in the Britax, you must. The Force is strong with this one. ... show more

    • Adaptable, cute, functional and safe!
Style: Highpoint Color: Purple Ombre
This seat is great! I love that it has the extra safety measure of holding the lap belt in the red clip. My daughter says the adjustable cup holders are better than the ones that are stuck. This was super simple to install and the adjustable height makes this easy and functional. I love the color! Fits great for growing children! ... show more

    • Brutal booster
Style: Skyline Color: Dusk
Finally my granddaughter can be safely buckled in without the ridiculous gymnastics required with that horrible crotch strap, which pinched her more than I want to admit. Easy to install, easy in easy out, attractive and stable. Super easy to adjust, and she loves it!

    • Great value and for older kids
Style: Skyline Color: Dusk
I recently purchased the Britax Skyline 2-Stage car seat, and I must say, I am extremely satisfied with my purchase. Firstly, the safety features of this car seat are top-notch. It is equipped with a 5-point harness system that securely holds my child in place, providing maximum protection in the event of a collision. The seat also features side-impact protection, which gives me peace of mind knowing that my child is safe from all angles. The seat is also easy to install correctly, thanks to the clear and intuitive instructions provided. The comfort level of the Britax Skyline 2-Stage car seat is outstanding. The seat is well-padded and provides ample support for my child's head, neck, and back. The adjustable headrest and harness height ensure a perfect fit as my child grows, allowing for maximum comfort and safety. The seat also features built-in armrests, which my child loves and finds very comfortable during long car rides. Another great feature of this car seat is its versatility. It is a 2-stage car seat, meaning it can be used in both forward-facing and booster seat modes. This allows me to use the car seat for an extended period of time, saving me money in the long run. The transition between the two modes is seamless and easy, thanks to the simple adjustment mechanisms. Cleaning the Britax Skyline 2-Stage car seat is a breeze. The seat cover is removable and machine washable, which is a huge plus for parents dealing with spills and accidents. The fabric is also high-quality and durable, ensuring that it will withstand regular use and frequent washings. Overall, I highly recommend the Britax Skyline 2-Stage car seat. It offers excellent safety features, superior comfort, and versatility. The ease of installation and cleaning are additional advantages that make this car seat a standout choice. Whether you're a new parent or looking to upgrade your current car seat, the Britax Skyline 2-Stage car seat is a reliable and worthwhile investment. ... show more

    • Great seat
Style: Skyline Color: Dusk
I bought this for my 7 year old grandson and he loves it! I was a little surprised how high it sits up but he loves being able to see out the window better. We have had quite a few out of town trips and he says that it is very comfortable. We have had this now a few months and have had no issues.
