R Exclusive, only available at Babies R Us Canada. 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 'infinite' recline and a machine washable ultra-plush premium seat pad round out the many parent approved features.

Exceeding 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.

It was overwhelming doing the research to find the perfect seat but we are SO glad we made the right choice by purchasing the Harmony Defender 360. It's sturdy, durable, safe, made well and of course, comfortable for our tiny passenger. In such a competitive market for children's car seat products, we are so glad we bought Harmony. We loved this car seat so much that we bought a second one! You won't be disappointed with this product. It's a MUST buy! :)</span> <div class="bvseo-pubdate">Date published: 2018-07-18</div> <meta itemprop="datePublished" content="2018-07-18" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="202944271"> <span itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating"> Rated <span itemprop="ratingValue">4</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author" itemtype="https://schema.org/Person" itemscope><span itemprop="name">Krisfy</span></span> from <span itemprop="name">Excellent dor the peice</span> <span itemprop="description">I bought this seat for the high harness position in order to keep my tall toddler harnessed as long as possible. The seat was easy to install and my daughter says it is comfortable. Con: the padding around the crotch buckle is a great feature but it is not attached and comes off when the child exits the seat. Con: the chest clip is very easy to undo (my 3 year old toddler was able to undo it while strapped in). For the price, it is still an excellent seat and it will become a backless booster when needed.</span> <div class="bvseo-pubdate">Date published: 2018-01-16</div> <meta itemprop="datePublished" content="2018-01-16" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="194035998"> <span itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating"> Rated <span itemprop="ratingValue">5</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author" itemtype="https://schema.org/Person" itemscope><span itemprop="name">dads4boyz</span></span> from <span itemprop="name">Highly recommend</span> <span itemprop="description">Excellent product we have purchased one for each of our boys for all 4 vehicles..Highly recommend.</span> <div class="bvseo-pubdate">Date published: 2017-09-10</div> <meta itemprop="datePublished" content="2017-09-10" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="193984669"> <span itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating"> Rated <span itemprop="ratingValue">5</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author" itemtype="https://schema.org/Person" itemscope><span itemprop="name">mom22</span></span> from <span itemprop="name">LOVE this seat!</span> <span itemprop="description">bought this seat for my twins, went on long road trip and they didn't complain once. much better than other brands I've used. easy to assemble, easy to install, and easy to use!

I was so excited to keep my 6 year old 51 inch tall son in a harnessed seat. Specs of the seat indicate the seat should fit a 57 inch height. I assembled the seat, sat him in it and realized he had only a half inch of harness height left to grow before he was out of it. Super disappointing. Great seat otherwise. Easy to adjust, not too heavy, feels solid and safe.</span> <div class="bvseo-pubdate">Date published: 2017-07-29</div> <meta itemprop="datePublished" content="2017-07-29" /> </div> </div> <script type="text/javascript"> if (document.getElementById('bvseo-reviewsSection')) { document.getElementById('bvseo-reviewsSection').style.display = 'none'; } </script> <!--end-reviews--> <ul id="BVSEO_meta" style="display:none!important"> <li data-bvseo="bvDateModified">y_2025, m_5, d_9, h_11</li> <li data-bvseo="ps">bvseo_bulk, prod_bvrr, vn_bulk_3.0.42</li> <li data-bvseo="cp">cp_2, bvpage2n</li> <li data-bvseo="co">co_hasreviews, tv_3, tr_13</li> <li data-bvseo="cf">loc_en_CA, sid_142FFA91, prod, sort_[SortEntry(order=SUBMISSION_TIME, direction=DESCENDING)]</li> <li data-bvseo="diagnostics">clientName_toysrus-ca</li> </ul> <!--end-bvseo-reviews--> <ul id="BVSEOSDK_meta" style="display: none !important;"> <li data-bvseo="sdk">bvseo_sdk, dw_cartridge, 18.2.0, p_sdk_3.2.0</li> <li data-bvseo="sp_mt">CLOUD, getReviews, 5ms</li> <li data-bvseo="ct_st">reviews, product</li> </ul>
