Canadian families count on the Harmony Defender 360 3-in-1 combination Car Seat on city streets or weekend road trips as the ideal solution for transporting your child. As the last car seat you will ever need, this premium multi-stage 3-in-1 car seat is comfortable, easy to use and comes packed with plenty of convenient features. The 1-touch, no-rethread harness height adjuster boasts the smoothest upfront harness adjuster available on the market. A unique recline and a machine washable ultra-plush premium seat pad round out the many parent approved features.

Complying with Canadian CMVSS 213 standards, US FMVSS 213 standards and European ECE standards, the Defender 360 leads the market with 360 degrees of full body impact protection with its deep supportive head and body structure and with its no-torque backrest. The deep, supportive headrest, backrest and seat base made with EPE energy absorbing foam cocoons your precious cargo and the unique seat structure disperses energy away from your child in the event of a crash.

Harmony’s stylish and modern seat design includes an ultra-plush pad made with premium, durable fabrics and extra high-density comfort foam for the coziest ride. The smooth-contoured seat-saver design protects your car’s upholstery while the smooth surface protects your hands during installation. The Defender 360 is also one of the only harnessed boosters that fit 3-across in most standard cars! At Harmony, we know Canadian families because we ARE a Canadian family. Fully dedicated to safety, comfort and incredible value, we are fulfilling our promise to help families enjoy travelling together.
