TinySeats is a bit of an unusual one with the isofix base. Again no crash test on it. It looks heavy. The inclusion of a booster mode seems strange and I wonder why they have done that, perhaps to make it seem like it lasts longer? But once you are in the booster age/stage, you will surely want a lighter and more practical travel option than this. I also wonder if including a booster option compromises on the other modes, it does seem to in most multi-mode seats for everyday use (that have been crash tested). However, great to have another option for rear facing if you want to, and the isofix plus support leg is likely to offer better protection from a frontal crash, though it doesn't look that different from the Urban Kanga for side impacts. As you note, needing isofix may be a problem. As you can see below, the Graco RightGuide offers a much bigger seating area. Kids who are big enough to get a good seat belt fit with both will need to decide whether they want to carry around the extra size of the RightGuide or be content with the smaller seating area of the mifold comfort. Either way, parents can rejoice that these kiddos are old enough to carry their own booster seats! When it’s unfolded it can shrink and expand every which way to fit a huge size range of kids – hence, the “hifold fit-and-fold” name.

Babies can move up to a forward-facing Group 1 seat when they reach 9kg, but we think this is far too early because their bodies may not be strong enough. It's safer to leave a baby rear-facing until they're at least 13kg or 15 months old - preferably longer. It’s much bigger and heavier than the Ride Safer travel vest or the Bubblebum, so families are less likely to have it for unexpected Uber rides If you're looking for a swivel baby car seat – that's a car seat with a rotating base – you'll be pleased to know there are now more models than ever that have this feature.For comparison, you can see her below in the same spot on the same day fit testing the Graco RightGuide. That seat has a 50lb minimum so she didn’t ride in it yet. But the lap belt fit is completely in the “green zone” from the IIHS chart above. The BubbleBum is the travel product our family has used most, hands down (see my complete BubbleBum review). We’ve had one since my daughter reached booster age and height. She used until her 10th birthday on all of our travels (when she finally hit 4’9” and could now go without!). My son has used the newer design of this very same product regularly when we rent cars or take Uber/Lyft at our air travel destinations.

Some carrycot car seats are suitable only for babies up to 10kg, which means parents might change to a forward-facing next-stage seat too early. One small change is the presence of those little gray triangles. They’re intended to decrease slipping on the seat when your child gets in though they were inadequate for my kids’ testing. A decade ago when parents of school-age children went on vacation, they generally left the booster seats at home. Some of them knew it wasn’t safe and preferred convenience, while others didn’t even realize the danger of using an adult seatbelt alone. Booster seats have come a long way since then, and there’s now a huge universe of portable booster car seats to keep kids safe while traveling light. Like the mifold comfort, the hiccapop Uberboost ( full review here) wasn’t ideal for our petite kids but could work well for bigger carpool buddies who sometimes ride with us. It’s another inflatable booster seat but gives a little more space for broader kiddos than the Bubblebum. It’s hollow inside so you can probably roll it small than this, and at 1lb 3oz it’s 6oz lighter than the mifold comfort. However, my kid hated the optional shoulder belt clip and won’t use the seat until he’s tall enough to avoid it. hiccapop Uberboost vs mifold: folded size mifold vs Graco RightGuide

My kids found the mifold a bit uncomfortable for sitting for long periods of time because it doesn’t have much padding. We also struggled to get the right belt fit a bit more than compared to the BubbleBum. But I know many families prefer it because it’s even more compact. The mifold can be a smart choice for shorter rides when space is really at a premium. Well, there’s obviously a huge difference in size. They just don’t even compare.The mifold is the smallest booster seat on the market.

What about at the top of the size range? The hifold is designed to fit kids up to 100 pounds and 59” tall! Wowza. I don’t have a kid that big to test it with, but it gets mighty tall as you’ll see below.In this review, I’m taking a look at one of the most innovative child safety products of the last few years: the mifold folding booster seat. Thanks to our partners at Carfoldio, I have the opportunity to get hands-on and in-depth with their upgraded version, the new mifold comfort.
