The Kin AP is a slim, practical convertible booster seat built to go from about 6 months up to 8 years, growing with your child from toddler mode to booster mode. Its narrow design makes it a great fit for families who need space — whether that’s three car seats across the back bench, or easy fitment in a small to mid-sized vehicle.

Despite its compact size, the Kin AP delivers on comfort and protection. It includes a plush infant insert, breathable ‘Cool Baby’ wicking fabric, and Air Protect™ side-impact protection to help safeguard your child’s head in the event of a collision.

As your child grows, the one-hand 5-position headrest adjustment makes transitions easy — no re-threading required. Two swing-out cup holders, a recline feature for installation flexibility, and arm rests round out a long list of parent-friendly touches.
