Oobr safe. Oobr cool. Clek Oobr is a high-back booster that revolutionizes booster seating. Its "firsts" include a seat frame that is now made with a high-impact copolymer, the rigid-UAS system and a unique recline feature. When the time comes, it can be easily converted to backless. Want more reason to love Oobr? It’s been rated a 'Best Bet' by the Insurance Institute for Highway Safety for nine consecutive years!
