Description

The Safety 1st Grand 2-in-1 Booster Car Seat is designed with versatility in mind. This highback booster car seat is made for families with growing children. In its initial mode, it functions as a 5 point harness booster seat, accommodating children in a forward facing car seat position from 30-65 pounds. As your child grows, it transitions into a belt-positioning car booster seat for weights ranging from 40-100 pounds. The Grand 2-in-1 Booster Car Seat meets or exceeds Federal safety standards. The lightweight design of the booster car seat makes it easy to transfer between vehicles. This booster carseat features deluxe fabric that includes textured nylon, smooth knit jersey, and lamination—providing a plush, comfy ride. The adjustable headrest offers customizable support for your child as they grow. This car seat for growing children including toddlers of at least 35 lbs. and big kids 40-100 lbs. provides great ergonomic support at key pressure points including the headrest, shoulders, back, and seat pad. Clean-up is a breeze with the removable pad of this child booster seat for car, which is machine washable and dryer safe. Two removable, dishwasher-safe cup holders offer convenient storage for drinks or small toys, making this harness booster seat practical.

    • Great car seat!
Color: High Street
My son fits perfect in it. It is super light so easy to transport. We needed another one since we have been back and forth sharing one car seat for both vehicles. There is no assembly required, height and sturdiness is not an issue.

    • Booster car seat
Color: Sunrise Coral
I absolutely love the Safety 1st Grand 2-in-1 Booster Car Seat! It’s very easy to install, and the seat feels sturdy and secure. The padding is soft and provides great comfort for long car rides. My child loves the bold, stylish color and sits comfortably without any complaints. The transition from harness mode to booster mode is smooth, and I appreciate how lightweight it is—easy to move between vehicles if needed. It also fits well in smaller cars, which is a huge plus. Highly recommend it to any parent looking for a safe, reliable, and affordable car seat that grows with your child! ... show more

    • Good Car Seat
Color: Black Sparrow
Bought this for a second vehicle that is not used a lot. Didn’t want to spend a lot of money on another car seat. This is great easy to install and comfortable for my kid. For a second or spare I recommend.

    • Good Seat
Color: Capri Teal
I love this seat. Unfortunately the top harness buckle on one of our two seats stopped working after about 18 months. I decided just to purchase the same seat again as we like everything else about it. Our daughter is almost 4 and still fits well in this seat. We love the two cup holders. Directions for installation are clear. Great seat for the money. ... show more

    • Great color, very comfy and affordable!
Color: Capri Teal
The most affordable car seat we’ve ever come across. Our son ruined his car seat beyond repair so we were on the hunt for a new one. But there so expensive now a days especially if you want a nice looking one. So we looked on here and found this one. It’s so nice and we adore the cup holders. Our son is 3 and loves his blue car seat! We’ve also never had a colored car seat but when we saw this we just knew he would love it. ... show more
