This is our third Hi Liner, our first in the new style. We had the older models for our older 2 kids. This is still a great seat! We went with other brands after being a safe n sound family for our capsule (awful) and newborn convertible seat while it was ok, we are so glad to be back with Safe n Sound. Comfortable, narrow, anti submarine gun clip, cup holders. They feel sturdy. I’ve always loved that the seat backs recline so no matter the incline of your car seat it will sit against it.

Bought this again as we had purchased the same seat for our son. The fact that it came in pink was a bonus, and was the only choice for our 5yr old little miss! Both kids love their seats and the drink holders are a nice touch. The rear safety strap is a great piece of mind. Recommend highly!

After reading many reviews on different booster seats, I decided this one was the right one. It turns out, the reviews did not lie. I am very happy with the purchase. My daughter loves the cupholders most. I loved how easy it was to install. Anyone who buys this booster seat will not be disappointed.

I have been very satsfied with this Booster seat , purchsed for a tall 4.5 year old. Easy to get in and out of and appears very comfortable. A great price compared to other stores who stock this product and friendly service. Istallation was very easy. I would recommend this booster seat , and Winkalotts , to others. Need to be aware that the cup holder is an addtional extra and does not come with the seat.
This is the second BSnS Hi Liner put into use for our grandchildren. The two grandchildren would argue over who would ride in the original Hi Liner. So, when the second had clearly outgrown the baby-seat, it became an easy decision to buy a second Hi Liner. The Hi Liner is easy to fit and set up, and is also easy to adjust later to accommodate a growing child. Recommended.
This is a sturdy seat, wide and has drink cups and toy storage both sides. It has the click in locks if your vehicle has the bar they clip onto and the std overseat belt clip in function. My granddaughter says “very comfy Nanny!” so I take her word for it. With a Prado I do feel a bit of effort is required to get the seatbelt secured due to width. Excellent product.
We purchased this for our very tall 4.5 year old. I was reluctant to put him in a booster but he had outgrown his harnessed seat, then I discovered the High Liner. What sold me was the anti submerging clip. But the fit of the seat is great, it is not to wide and my son is super comfortable and stays comfortable even when he falls asleep. Would highly recommend this seat, easy to install.
My son graduated from the baby/toddler seat and he loves it. Easy to install and much easier to get in and out off. I'm not allowed to click it in as it's "that's my job mummy". Suits me. Love the colour. Perfect for a boy. Now we have a budding race car driver in the back seat. Baby Bunting delivered in 2 days, so super happy with the service. Emails at every change of the process, so I knew exactly how my purchase was tracking. Thank you.
We bought this seat to replace the 0-4 years baby seat with five point harness. We spent hours researching online to find a safe car seat, before settling for this one. It is not five point harness safe, but very comfortable and really safe for the fast growing kid. Provision to avoid submarining is a pretty good safety feature. I would recommend this seat to anyone.
Bought this as the reviews said it was the most comfortable booster seat, as well as one of the safest. It also has a long working life due to the ability to extend the height beyond most others. We weren't disappointed, our Sons love them and there are no longer any complaints about being uncomfortable. The SecureGuard clip is an added bonus and the kids quickly learned how to clip that on themselves. Couldn't be happier with them.
