First impressions: it looks slick and modern, definitely one of the more stylish options in its price range. One of the standout features for us was how lightweight it is. Our son was able to carry it to the car and install it himself with minimal help, which gave him a sense of independence and made transitions between vehicles much easier. Comfort-wise, he gave it a thumbs up. The padding and design seem to suit him well, even on longer drives. We&rsquo;re using it with the high back booster, and at nearly seven years old, he&rsquo;s already at the highest setting, something to keep in mind if your child is tall for their age. The main downside we&rsquo;ve noticed is stability. Around corners, the seat has a tendency to lean slightly to one side, which makes it feel less secure than we&rsquo;d like. It&rsquo;s not unsafe, but it does leave us wishing for a more anchored or tethered setup to keep it firmly in place. All in all, it&rsquo;s a good-looking, comfortable booster seat that&rsquo;s easy for kids to manage on their own. For the price, it delivers on style and convenience, I just wish it felt a bit more locked in during turns.</span> <div class="bvseo-pubdate">Date published: 2025-10-04</div> <meta itemprop="datePublished" content="2025-10-04" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="359635128"> <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">DStrawberry</span></span> from <span itemprop="name">This seat has it all</span> <span itemprop="description">[This review was collected as part of a promotion.] We absolutely love the Growmate 2-in-1 Booster! From the moment we took it out of the box, it was a win&mdash;super easy to assemble and install, which made setup stress-free. One of my favorite features is the easy-clean fabric. It&rsquo;s perfect for everyday messes and wipes down beautifully, plus the cover is machine washable, which is a huge bonus for busy parents. The slim, compact design is a game-changer for our truck where space is tight. It fits perfectly without compromising on comfort or safety. It&rsquo;s also lightweight and really easy to move between vehicles, which we do often. Our kiddo finds it incredibly comfortable and loves that they can buckle themselves in with ease, thanks to the well-placed belt guides. It&rsquo;s great to see them gaining independence while still being safe. We even tested it out with our almost 9-year-old, and it adjusted perfectly&mdash;thanks to the 12-position headrest and overall thoughtful design. It's clearly built to grow with your child, and it really delivers on that promise. The added cup holder is a nice touch (and dishwasher safe!), and I love that everything stores neatly under the seat when not in use. If you&rsquo;re looking for a reliable, well-designed booster that&rsquo;s comfortable, compact, and easy to maintain, this is the one. It comes highly recommended by our family.</span> <div class="bvseo-pubdate">Date published: 2025-09-20</div> <meta itemprop="datePublished" content="2025-09-20" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="356942053"> <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">SaraMom</span></span> from <span itemprop="name">Comfy and Lightweight</span> <span itemprop="description">[This review was collected as part of a promotion.] I recently got the Safety 1st Growmate 2-in-1 Booster, and I&rsquo;ve been very happy with it so far. Installation was simple and straightforward, and the cup holder is really convenient for drinks or snacks. One of my favorite features is the easy-to-use carry handle &mdash; it&rsquo;s lightweight enough that even my 6-year-old can pick it up and carry it themselves. We just used it on a longer car ride, and my child said it was very comfortable, which gave me peace of mind knowing they were secure and happy the whole way. Overall, it&rsquo;s a practical, kid-friendly, and parent-approved booster seat.</span> <div class="bvseo-pubdate">Date published: 2025-09-10</div> <meta itemprop="datePublished" content="2025-09-10" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="356636904"> <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">Ahm123</span></span> from <span itemprop="name">Kids and mom love this booster</span> <span itemprop="description">[This review was collected as part of a promotion.] This is a great, lightweight and easy to install booster seat! The back comes off super easy for when I&rsquo;m travelling and the odd time I switch and use it for my bigger kiddo. The black colour is super sleek and the cup holder is the perfect size for kid cups and water bottles. I love that my 4 year old can use a booster with her shoulder strap properly positioned - it adds a lot of relief in terms of her safety in the back seat. Would definitely recommend this booster for a family on the go!</span> <div class="bvseo-pubdate">Date published: 2025-09-05</div> <meta itemprop="datePublished" content="2025-09-05" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="356594291"> <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">Mich</span></span> from <span itemprop="name">Slim and light</span> <span itemprop="description">[This review was collected as part of a promotion.] I had been using a convertible car seat in booster mode, but I didn&rsquo;t like that it was so cumbersome, heavy and bulky. I love this booster because it&rsquo;s slim &amp; lightweight. My son can easily get in and out of it himself and I have more room in my car now. I love that it has an adjustable height headrest &amp; removable highback so I can feel good about using it as my child grows. Installation is straightforward, and because it&rsquo;s so light, I can easily remove/reinstall as needed. The only thing I do not like about this car seat is that my son complains of the seatbelt bothering his shoulder. He does not find that part as comfortable as his old convertible car seat in booster mode.</span> <div class="bvseo-pubdate">Date published: 2025-09-05</div> <meta itemprop="datePublished" content="2025-09-05" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="356473457"> <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">Ang3la</span></span> from <span itemprop="name">Happy switch to a booster</span> <span itemprop="description">[This review was collected as part of a promotion.] I&rsquo;d been so hesitant about moving my daughter to a booster seat but this honestly made the transition much easier than I was expecting. Not only was my daughter extremely excited to get a new &ldquo;big girl seat&rdquo; for the car to use the real seat belt like her friends, but the installation was so easy compared to a convertible seat because it is so lightweight which made lifting it into the vehicle and positioning it a breeze. We are using it in the high back mode because my daughter is not ready for backless yet, but switching it to backless is really easy for when the time comes. We made her practice buckling it herself and it has made going places easier because she is proud of buckle herself in with the seatbelt while I get her sister in the car. We also love how easy it is to move from one vehicle to another so if she visits her grandparents or goes with a friend then no one is in for a huge workout of moving heavy seats around. My daughter also says it is much more comfortable than her convertible car seat was.</span> <div class="bvseo-pubdate">Date published: 2025-09-03</div> <meta itemprop="datePublished" content="2025-09-03" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="356403212"> <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">Elizabeth</span></span> from <span itemprop="name">Lightweight and easy to use</span> <span itemprop="description">[This review was collected as part of a promotion.] I used the high back version of this booster seat for my 7 year old son. It was very lightweight and easy to install. Easy to use as the instructions are very straight forward and it is very clear where the seat belt runs and how to ensure it is properly fitted for my child. Only complaint is that it does not attach to the car via anchors so it feels slightly less secure. I would feel more comfortable using it for a bigger child, as my son is fairly small for his age. Overall, great product for a larger child!</span> <div class="bvseo-pubdate">Date published: 2025-09-03</div> <meta itemprop="datePublished" content="2025-09-03" /> </div> <div class="bvseo-review" itemprop="review" itemscope itemtype="https://schema.org/Review" data-reviewid="356151224"> <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">Olivia</span></span> from <span itemprop="name">Amazing Booster Seat</span> <span itemprop="description">[This review was collected as part of a promotion.] This booster seat is amazing! My kids love it and find it comfortable and there's no installation! It just sits on the seat so it's easy to switch from car to car. I love the high back option as it puts the seat belt in the correct spot on my son's shoulder rather than it cutting into his neck. The non high back option is also great for when my son gets a little taller and the seat belt sits correctly on him. I absolutely recommend this seat to anyone looking for a good, durable booster seat that your children are safe and secure in. I also like that it comes with a cup holder for when we're out and about.</span> <div class="bvseo-pubdate">Date published: 2025-08-31</div> <meta itemprop="datePublished" content="2025-08-31" /> </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/Safety-1st-Growmate-2-in-1-Belt-Positioning-Booster-Car-Seat/E4D03993.html?bvstate=pg:2/ct:r">Safety 1st Growmate 2-in-1 Belt Positioning Booster Car Seat Reviews - page 2</a></li> </ul> <!--end-pagination--> <ul id="BVSEO_meta" style="display:none!important"> <li data-bvseo="bvDateModified">y_2025, m_11, d_1, h_6</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_0, tr_27</li> <li data-bvseo="cf">loc_en_CA, sid_E4D03993, 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>
