Choosing between the three comes down to your child's current stage and your vehicle. Consider the Oobr if your child still benefits from extra head and neck support, or if your back seat lacks an adjustable headrest. The right backless booster between the Olli and Ozzi will depend on your child's size and your vehicle — our team can walk you through the differences in store. All three share the same UAS anchoring hardware.

Yes. Every Clek booster sold in Canada, including the Oobr, Olli, and Ozzi, is manufactured to meet Transport Canada's requirements and CMVSS, the Canadian Motor Vehicle Safety Standards, the same standards that apply to every booster seat sold in Canada regardless of brand. Clek is a Canadian company, so its boosters are engineered around Canadian regulations from the start, rather than adapted afterward from a US design. Always confirm the specific weight and height limits printed on your chosen model.

Clek boosters generally fit children from about 40 lbs and age four through the booster years, with the exact upper weight and height limit varying by model between the Oobr, Olli, and Ozzi. As with any booster, your child should be able to sit upright for the whole ride, without slouching, unbuckling, or leaning sideways. Because the three models cover slightly different ranges, check the specific weight and height limits printed on the product page for the model you're considering.

In Canada, the connection point Clek calls rigid-LATCH is governed by UAS, the Universal Anchorage System — the term used in Canadian car seat regulations. Rigid-LATCH is Clek's brand name for its anchoring connectors; UAS is the Canadian regulatory term for the same anchor points built into your vehicle. Functionally it works the same way: rigid connectors clip into the vehicle's built-in anchors, so the booster stays securely in place in the back seat even when your child isn't in it, rather than sliding around loose. This is separate from the seatbelt, which still restrains your child during the ride.
