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

He is on the smaller side and we wanted something that we knew would last for the many years to come he will be needing a booster seat. We have always loved Britax because of their highly rated safety and the quality of the overall product. Some may say its on the higher end of the price range but I truly believe that this is worth EVERY PENNY! We are a two car family so having a seat that is easy and quick to take out and put in the car is a must. I love the lift up feature as there is no more having to fish the seat belt behind the seat while in the small space of a car. My son is able to buckle himself in which is a huge plus for a mom with 4 kids! Once he buckles we just check to make sure it secure and tight. Lastly, the seat is very comfortable and my child is able to sit in it without complaints for long car rides. I am a huge fan of the head rests so my childs neck is fully supported when he is sleeping. Over all this is a great seat and we will for sure be purchasing another one when our second son is able to begin front facing in his car seat! Once again a HUGE thank you to Stellar Panel for providing me with another amazing product to test as part of the Stellar Product Testing Panel.</span> <div class="bvseo-pubdate">Date published: 2022-12-29</div> <meta itemprop="datePublished" content="2022-12-29" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="152879095"> <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">kidstuffgirl2</span></span> from <span itemprop="name">Simple to Clean and built in &quot;Sauce Space&quot;</span> <span itemprop="description">[This review was collected as part of a promotion.] We were given the Britax Grow With You Harness-to-Booster Car Seat to try out from the Stellar Product Testing Panel. My daughter and I were pretty excited to upgrade her to a big girl car seat like her older brother. She&rsquo;s a preemie and petite, so it&rsquo;s taken her much longer to get big enough for a safe upgrade. As a mom to 3 kiddos who are five years old and under, I was pretty interested in seeing if it really was easy to install and remove the fabrics for cleaning. We went on a road trip to visit my grandparents and later visited an amusement park over Christmas break. That meant we had many snacks and naps to give this car seat a real test drive. First Up: Snacks! Our favorite on the go meals are nuggets and fries. My daughter liked her, &ldquo;Sauce Space&rdquo; (at least that&rsquo;s what she decided the bonus snack area behind her cup holders were for.). In practicality, she had to kind of bend her arm funny to dip in her sauce because it sits directly under the armrest, but she didn&rsquo;t mind (and I liked that she wasn&rsquo;t holding it and spilling it all over herself). As for naps, this car seat wasn&rsquo;t quite as comfortable as her reclining baby car seat. When she slept, her head tilted forward and to the side and that resulted in a sore neck and crying toddler when she woke up. Honestly, that&rsquo;s not really preventable when you have an upright, big-kid car seat though, so I don&rsquo;t fault the seat itself. I appreciated that it didn&rsquo;t take more than 5 minutes to read through the manual and adjust the seat to her best height. Moving the buckle to a different setting confused me at first, but after I did it, I felt kinda silly for not understanding it at first. It&rsquo;s really simple to do. Installing the car seat with the anchor and my van&rsquo;s built in seat belt was really easy too. I didn&rsquo;t bother with latch straps, but it doesn&rsquo;t look hard. After we got home from our 2nd trip, the snack spills demanded cleaning. I was delighted that the covers really are easy to remove and put back on. Washed up great in the washer and only having 2 pieces to clean was nice because it is so straightforward (especially compared to her brother&rsquo;s 3 complicated pieces). I would definitely recommend the Grow With You Harness-to-Booster. It&rsquo;s built to last till she is ready for the vehicle&rsquo;s built in restraint and it seems easy to adjust and keep maintained while she grows up. I have a 45 minute commute to work every day, so thank you again to Britax and the Stellar Product Testing Panel for keeping my kiddo safe during all our travels.</span> <div class="bvseo-pubdate">Date published: 2022-12-29</div> <meta itemprop="datePublished" content="2022-12-29" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="152875563"> <span itemprop="reviewRating" itemscope itemtype="https://schema.org/Rating"> Rated <span itemprop="ratingValue">3</span> out of <span itemprop="bestRating">5</span> </span> by <span itemprop="author" itemtype="https://schema.org/Person" itemscope><span itemprop="name">Kathleen</span></span> from <span itemprop="name">Mediocre car seat that will grow with your toddler.</span> <span itemprop="description">[This review was collected as part of a promotion.] I received the Britax Grow With You Harness-to-Booster Car Seat from the Stellar Product Testing Panel. I was very excited to test this product! However, this car seat was incredibly difficult to install. Even when the seat was tethered, it moved around more than an inch. It was also a struggle to adjust the straps and harness features when trying to strap my child safely in. The feature I liked the most was how padded the seat was. I also like how the covers are easily removable to be cleaned. We all know this is very important for both toddlers and busy moms, such as myself. In addition, I appreciated the double cup holders and that they didn&rsquo;t take up too much room (I have another car seat in the car as well). My daughter was also comfortable in it. I look forward to using the booster feature when my toddler is big enough.

I like britax products for safety and looks. The grow-with-me seat was easy to install, and my almost 4 year old reports that it is a &ldquo;really comfortable and really cool big boy chair&rdquo; and he also says he can see more stuff out the windows. I also like how easy it is to remove the padding and clean it, that definitely gives this seat some points. I also like that Britax does not add any flame retardant chemicals to their baby products. I like the harness for younger kids. My son is tall but slim, so we do have to tighten the harness quite a bit, and it is challenging to adjust. The strap is so long, I have to pull several times, while releasing it with my finger so that it feels secure, I&rsquo;d like that to be easier. It&rsquo;s a bit bigger than our other convertible car seat, so if you need three across, there may not be room depending on the car you drive.</span> <div class="bvseo-pubdate">Date published: 2022-12-28</div> <meta itemprop="datePublished" content="2022-12-28" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="152848183"> <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">mcdiverest</span></span> from <span itemprop="name">Fantastic booster seat</span> <span itemprop="description">[This review was collected as part of a promotion.] I was given this booster seat to try as part of the Stellar Product Testing Panel, but the thoughts and reviews are my own. I absolutely love this car seat/booster seat! It was incredibly easy to install in my car, which I can't say I've experienced before. The size is absolutely perfect and my son says it's incredibly comfortable. I love that I can easily clean this material as well. While my son is not in a booster seat just yet, he's right on the cusp so I played around with making it a sole booster, and that was even easier than the initial install. It's high quality, feels incredibly safe and I love that my son loves being in it. I think this will be a perfect fit while we grown through the different stages of needing a car to a booster seat.</span> <div class="bvseo-pubdate">Date published: 2022-12-28</div> <meta itemprop="datePublished" content="2022-12-28" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="152846430"> <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">RebeccaJ</span></span> from <span itemprop="name">Squeaky at first but good quality</span> <span itemprop="description">[This review was collected as part of a promotion.] This was the first forward facing seat my 3.5 yr old used and she loves it! I found it extremely easy to install. I glanced at the instructions before installation then again after installation to ensure I did everything correctly. It was very intuitive. I did not find adjusting the height of the back to be easy initially but by the 3rd try I was a pro. The fabrics are all very comfortable and I like the way they are positioned. My daughter confirmed it feels very smooth. It seems like it will be easy to clean when we inevitably need to throw it in the wash. The first few days there was a loud squeaking noise from the headrest that I was not able to make stop despite a full read through of the directions and multiple stops on the side of the road as I attempted to fix it. After 4 days the noise went away on its own for when my daughter is not in the seat. It still occasionally squeaks when we are on a bumpy road and my daughter is in the seat. My daughter does not mind the noise and is still loving the seat after 2 full weeks of using it multiple times a day. Her favorite feature is the FOUR cup holders so she now has easy access to snacks, a drink, a pinecone, and whatever toys she fits in there.

My son, who just turned 4, had been using a convertible seat until the start of the school year, when we moved up to a transitional type booster (not this one). I mention coming from another booster so you better understand my appreciation for the Britax Grow With You Harness-to-Booster seat. Within the first 2 weeks in my prior booster, I regretted my purchase. It was a blessing when 3 months later, we received the Britax. The first and most important feature for me that made this switch necessary (missing on my other) was the extended head support. When we went from convertible to the &lsquo;big boy&rsquo; seat, we quickly realized how uncomfy my son was when tired, as the seat lacked the extended side head support he was used to. It also gave me a ton of anxiety, as his head would just be bobbling and dangling around which was very unsettling. The Britax Harness-to-Booster offers little ones the independence of a booster (they can get in the seat easily on their own), while providing the safety, comfort and support of a convertible. The arm rest and dual cup holders are also a nice added feature and my son loves both! The fabric is nice and soft and can be easily removed and washed, though we havent done this yet. The height was easy to adjust and installation with LATCH was simple (though out of the box, the connectors come tucked and latched deep inside the seat which was a bit cumbersome to get out.) The one thing I find to also be slightly overexerting is the actual harness adjustment. Getting used to it now but it does seem like in general, it takes more effort to tighten than others I&rsquo;ve had (unless I&rsquo;m just doing it wrong) and the adjustment button is a bit oddly placed. Those minor things aside, I am very pleased with this seat and beyond relieved to have made this switch.</span> <div class="bvseo-pubdate">Date published: 2022-12-28</div> <meta itemprop="datePublished" content="2022-12-28" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="152846016"> <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">MomOfFive</span></span> from <span itemprop="name">Kod Tested, Kid Approved!</span> <span itemprop="description">[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this booster seat. The moment the box arrived, I made sure to put it to use right away so that I can give my honest and thorough feedback on what I observed. I'm a mother of 5 children and I've been through many booster seats over the years. I would have to say that this one is by far the best one that I've ever used! I can't list just one feature that is my favorite with this car seat, so I'll just list a few. First feature that I liked about this car seat is the fact that there are cup holders. Without the cup holders, there would be a big drink mess all over my seats and floors. I absolutely love that the fabrics are naturally flame-retardant, and cleans very easily. The fact that I can just wipe it clean instead of having to wash it every time there's a mess on it is a huge hit for me! Being able to adjust the car seat to find the best fit for my child was extremely easy. My daughter even seemed to have fun helping me find the perfect fit for her.</span> <div class="bvseo-pubdate">Date published: 2022-12-28</div> <meta itemprop="datePublished" content="2022-12-28" /> </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_2024, m_4, d_26, h_5</li> <li data-bvseo="ps">bvseo_bulk, prod_bvrr, vn_bulk_3.0.42</li> <li data-bvseo="cp">cp_1, bvpage1</li> <li data-bvseo="co">co_hasreviews, tv_4, tr_119</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, 6ms</li> <li data-bvseo="ct_st">reviews, product</li> </ul>
