Grow With You™ Harness-2-Booster grows with your child from toddler to big kid.

2 layers of Side Impact Protection include an energy-absorbing shell, foam-lined headrest, and external cushions that surround the head, neck & torso.

SafeCells in the car seat base create a crumple zone that absorbs crash energy.

Quickly adjust the 9-position harness & headrest using just one hand for the proper fit as your child grows.

Once your child is ready to use the seat belt, the 5-point harness tucks away, transitioning to a belt-positioning booster. Color-coded guides help you and your child route the belt through the right paths.

With easy-to-clean arm rests, cup holders, and snack storage, even big kids enjoy the ride.

  • Harness mode 25lbs - 65 lbs (11 to 30 kg ); Booster mode 40 lbs -120 lbs. (18 to 55 kg ).
  • SafeCells in the car seat base create a crumple zone that absorbs crash energy to help keep it away from your child.
  • Industrial Strength Steel frame reinforces the seat structure to help keep it stabilized.
  • V-shaped tether with staged-release stitches helps slow and reduce forward movement during a crash.
  • 2 Layers of Side Impact Protection: Energy-absorbing shell and foam-lined headrest protect the head, neck, and torso.

And since it&rsquo;s for my first baby, I was really looking for something safe and high quality, because it will likely be used by one (or more) of her younger siblings, too. Although my daughter&rsquo;s forward-facing car seat that she used previously looks bigger and bulkier, I was surprised at how heavy the Grow With You Harness-2-Booster Car Seat is in comparison. It looks light, but I really appreciate that it has such good density. It makes me feel like it&rsquo;s very sturdy and safe. (I guess it&rsquo;s that steel frame!) When installing the car seat, I prefer to use the LATCH system, and was able to hook and unhook the booster seat easily into my car. My husband, however, prefers using the seat belt to install the booster seat. He really likes how you pull down the back part of the seat so you can see the seat belt while installing it. Many car seats make you go &ldquo;blind&rdquo; as you stick the seat belt through a hole near the bottom and try to pull it all the way through, but you have a full visual with this booster seat. And my daughter&rsquo;s favorite feature is definitely the two cup holders and two snack holders! Although she usually uses them to stash toys that she brings with her in the car, not necessarily food and drink. Since I&rsquo;ve only used it with my daughter for a few weeks, I haven&rsquo;t needed to adjust the fit, besides initially setting it up (which I was able to do so easily), but since this grows with her until she weighs over 100 pounds, I am grateful that it is fully adjustable. Especially since this will probably be used by a younger sibling in the future, so my daughter can use it as a belt-positioning booster until she&rsquo;s big, and then I can adjust it back to a five-point harness for a smaller, younger sibling. Although I received the Grow With You Harness-2-Booster Car Seat through the Stellar Product Testing Panel, I will buy another in the future for my second child (who will need one before my daughter grows out of it), and I highly recommend it to anyone else!</span> <div class="bvseo-pubdate">Date published: 2020-10-04</div> <meta itemprop="datePublished" content="2020-10-04" /> </div> </div> <script type="text/javascript"> if (document.getElementById('bvseo-reviewsSection')) { document.getElementById('bvseo-reviewsSection').style.display = 'none'; } </script> <!--end-reviews--> <!--begin-pagination--> <ul id="bvseo-paginationSection"> <li class="bvseo-paginationItem"><a class="bvseo-paginationLink" href="https://www.babiesrus.ca/en/Britax%C2%AE-Grow-with-You-Harness-2-Booster--Dusk/C4961BF5.html?bvstate=pg:2/ct:r">Britax&reg; Grow with You Harness-2-Booster, Dusk Reviews - page 2</a></li> </ul> <!--end-pagination--> <ul id="BVSEO_meta" style="display:none!important"> <li data-bvseo="bvDateModified">y_2022, m_12, d_8, h_21</li> <li data-bvseo="ps">bvseo_bulk, prod_bvrr, vn_bulk_3.0.34</li> <li data-bvseo="cp">cp_1, bvpage1</li> <li data-bvseo="co">co_hasreviews, tv_4, tr_92</li> <li data-bvseo="cf">loc_en_CA, sid_C4961BF5, 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>
