Very good seat and great value
Great car seat. Lightweight but sturdy and my granddaughter declares it to be very comfortable. Handy pull out cup holder on each side. It was very easy to adjust the headrest to the right height.

Perfect car seat
Excellent quality. My 6 year old granddaughter loves it and doesn’t take up much space in the car. Extremely simple to fit. Has 2 cup holders and I purchased a separate cushion for the seat belt incase she falls asleep. Very sturdy so yeah would definitely recommend x

Price, comfort and additions
Overall a really good junior car seat and has 2 really handy cup holders, nice and wide so great for kids on the bigger side without feeling squished, headrest is fantastic for those that still fall asleep in the car as keeps there head nicely positioned without flopping around, also turns into a booster seat and cant beat the price. Would definitely recommend and buy again in the future if needed.

Safe, comfortable, and easy to use!
I’m very pleased with the Graco Junior Maxi i-Size Booster Car Seat! It’s a great option for keeping my child safe and comfortable during car rides. The seat is easy to install, and the adjustable backrest ensures a snug fit as my child grows. The padding is soft, and my child finds it comfortable for longer trips. The side-impact protection gives me peace of mind, knowing my little one is well protected. I would definitely recommend it for anyone looking for a reliable and affordable booster car seat.

Perfect
My kids are already 4 and 5 so the eggshells were not comfortable for them. This seats are perfect, comfortable, easy to keep clean. Will stay with us many years for sure.

Günstig und trotzdem stabil und zuverlässig
Preiswert und trotzdem sehr gut. Das Kopfteil kann in der Höhe verstellt werden und hat auf jeder Seite einen Becher/Flaschenhalter. Das Kind wird durch den normalen Gurt, der oben im Schulterbereich durch eine Gurt-Führung und über den Hüftbereich geführt wird, fixiert. Der Sitz ist leicht doch durch den Gurt wird er sehr gut befestigt. Bin sehr zufrieden damit

Bilstol till vettiga pengar
Jag köpte denna barnstolen eftersom barnbarnet blivit för stor för att åka i bakåtvänd bilstol. Barnets far monterade denna stolen på plats och enligt honom är stolen perfekt! Barnbarnet är nöjd, barnets far är nöjd och min fru är jättenöjd så då kan betyget bara bli full pott!

Aisé à monter, à transporter, et confortable, combo gagnant !
Siège rehausseur acheté pour mon fils qui fait 1 m 38. Le montage est intuitif, le siège est léger à transporter et dispose d'un appui-tête facilement réglable grâce à une poignée. Sur un trajet en voiture de 2 fois 10 heures, mon fils s'est senti assez à l'aise. Je recommande.
