The Kobuk Air-Thru™ booster seat with vented shell allows hot air to escape and cool air to rush in. It can be used as a highback or as a backless booster, keeping your child safe after he or she out-grows a car seat. Deep side wings provide greater head protection. Belt guides give you the freedom to adjust the seatbelt vertically or horizontally so you can find the perfect belt position for your child. The height adjustable backrest, armrests and removable cup holder make for a comfortable environment. Removable and washable fabric adds convenience.
