Made with a hard plastic interior, an ergonomic padded back and a removable cover, the car booster seat is comfy, easy to clean and tough enough for everyday use.

Less stress. More smiles. Making travel child's play. *Extra charges may apply. Be sure to check with your airline ahead of your trip. Review: Este alzador-mochila está genial, Trunki destaca por la calidad de sus materiales y acabamos de los mismos, la mochila en sí pesa demasiado para que un niño/a de la edad indicada lo pueda llevar y menos si tiene algún objeto más dentro. En cuanto a tamaño es muy bueno para niños más altos y más fuertes, caben perfectamente y tiene reposabrazos. Es muy fácil de instalar y recoger. Review: Il seggiolino risulta ottimo..resistente e al pari di un rialzo normale da auto in quanto ha un anima in plastica che ne determina la seduta (comunque morbida e confortevole grazie al rivestimento ) e i due braccioli laterali che si rialzano e si fissano con un tlac(e poi x richiuderli ha un bottoncino solo da premere).Lo schienale pensavo rimanesse sfloscio sul dietro invece ho notato che rimane preciso dritto dietro la schiena. Lo zaino non ha enorme capienza ma sicuramente per giochini o cosine varie è più che sufficiente. il tessuto sembra di quelli lavabili impermeabile. Ha l interno di una delle orecchiette dello schienale con la possibilità di scrivere il nome e telefono in caso di smarrimento. Sono rimasta molto soddisfatta dell acquisto! ## Features - Car Booster Seat & Backpack in One: The Trunki BoostApak is your 2-in-1 R129 booster car seat that doubles as a kids travel backpack!

Ze kunnen er hun spullen in kwijt, het dragen als rugzakje en als ze teruggebracht worden met de auto, kunnen ze ook nog veilig vervoerd worden op de zitting verhoger. Of gebruik het voor je vakantie in je huurauto. Er zijn genoeg voordelen en gebruiks momenten de noemen. Maar er zijn helaas ook wel nadelen. Het werkt helaas niet vanzelfsprekend, waardoor het voor een onbekende niet enorm makkelijk is om uit te leggen. Er zijn ook wat ongemakkelijke handelingen te verrichten. Met name als het zitje van gordelzijde moet veranderen. Maar dan nog is het altijd compacter en multifunctioneler dan een gemiddelde zitting verhoger. ## Frequently Bought Together - Trunki BoostApak | Kid's Travel Backpack and Portable Child Car Booster Seat | Group 2-3 | Ages 4 – 12 Years (Pink) - Trunki Seat Belt Pads for Kids | Comfy Childrens Seatbelt Cover | for Car Seats and Pram - SnooziHedz (Pink) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/283597237-trunki-boostapak-car-booster-seat-r129-certified-high-back-booster](https://www.desertcart.us/products/283597237-trunki-boostapak-car-booster-seat-r129-certified-high-back-booster) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
