On a recent field trip day at my son’s school, I was watching kindergarten to second graders try to lug around their booster seats and car seats, and watching volunteer parents try to figure out how to strap the car seats into their cars. (I personally just volunteered to drive, because it was easier than unfastening and refastening my son’s car seat!) Then, one child came up holding this little thing the size of a clutch purse, telling me it was her car seat. (Image from Amazon)
I talked with the mother a little, but was having a hard time seeing how this could possibly be safe – so I did my research. (Meaning – I contacted a friend who is a CPST carseat technician and asked her! She gave me some great articles to read.)
The seat was a mifold Grab-and-Go Car Booster Seat. It’s advertised as being
- More than 10x smaller than a regular booster seat and just as safe
- The most advanced, compact, and portable booster seat ever invented designed for kids aged 4 and up, 40 to 100 lbs, and 40 to 57 inches tall
It’s available for around $40.
At first glance I didn’t understand how it worked… I thought the purpose of a booster seat was to get the child up high enough that the shoulder belt goes across their chest, not across their neck. This seat is 3/4 of an inch thick, so how does it work?
Instead of thinking of the mifold as a booster seat, think of it as a belt-positioner. Instead of lifting the child up, it pulls the seatbelt down. The belt guides on the seat ensure that the lap belt goes low across the child’s hips (not their belly – on top of all their internal organs, and not on the thighs where they could slip forward in case of an accident.) The strap pulls the shoulder belt down lower, so it will go across the child’s shoulder and chest, not their neck.
To transport, it folds up very small, with the strap wrapped around it. To install it, you unfold it, press a button to open the seat belt guides up wider (there are three possible widths to adjust to your child’s size). Use the setting that is closest to your child’s thighs without touching their thighs. Once child is seated on the mifold, you take the lap belt through the belt guides on the seat, then use the strap to clip the shoulder belt down at the right height. (Watch the videos on Amazon or in the reviews.)
Check for proper belt fit: the lap belt must fit snugly, low across the hip bones, just touching the top of the things. The shoulder belt should be across the center of the shoulder.
It appears that the mifold works very well with many children in many vehicles. However, in some vehicles, it just can’t position the belts correctly, which means it would not be safe in a crash.
Here are detailed reviews of the mifold, from Car Seat Blog and Car Seats for the Littles. Here is a video review. Here’s another video review. (Note: the video reviewers do not appear to be car seat experts.) Here are the ease of use ratings from the National Highway Traffic Safety Administration.
Safety note: the IIHS, the Insurance Institute for Highway Safety, will not rate the mifold because, instead of raising the child up, “the device pulls the belt down to the child. There aren’t any data about how this new type of device works with real kids in real crashes. For these reasons, the Mifold isn’t comparable to the boosters that IIHS evaluates and isn’t included in the ratings.”
The consensus of the reviews cited above, and user reviews on Amazon:
Pros: Incredibly portable! Great for travel, taxis, and so on. Affordable. Older children are not embarrassed to use it, as they may be with another booster when their friends have outgrown theirs.
Cons: Won’t fit all kids in all cars. Can slip around on seat or fold up a bit, which can make it hard to get into. Younger children won’t likely be able to buckle and unbuckle themselves as this is a bit tricky.
My personal choice, as a mom – not as an expert in the field – is that the next time I go on a solo trip with my son, I’ll get a mifold. As a handicapped mom (I have one leg), being able to tuck his carseat into a suitcase instead of having to schlep a separate seat around airports is a huge advantage to me. But for this week’s trip when my husband will be with me, we’ll just stick to our traditional backless booster. We’ve got two 2-hour drives and two 4-hr drives so want to ensure he’s comfortable and up high enough to see out the window of our unknown rental vehicle.
For our everyday use, my son is still in a 5 point harness seat in my car and my husband’s car, or in a traditional booster for the once a week ride with grandpa or school field trips where I won’t be around to help ensure it fits properly in another parent’s car. I want him to be as safe as possible, so I always keep him at each level of car seat as long as I can. (My son is 8, but he’s just 50 inches and 52 pounds, so he’s got a long ways to go before he maxes out the height and weight limits on seats.)
But if a highly portable carseat is a necessity for you, this may be a good option.
The mifiold is available at Amazon, Target and elsewhere.
Some alternative small portable booster seats to consider for travel, carpooling, field trips, after school playdates, visits with grandparents, taxi or bus rides:
BubbleBum Inflatable Backless Booster Car Seat, Black. Here’s a review of the BubbleBum. This is an inflatable booster seat! So, it weighs one pound and squashes up small in the suitcase. $27
Ride Safer Delight Travel Vest, Small Yellow – Includes Tether and Neck Pillow cost around $150. This is a vest that you buckle child into, then buckle it into the car. Comes with a bag so kids can carry their own seat easily. Helpful when there’s not enough space in the back seat to fit three car seats in a row. Putting one child in this travel vest can solve that problem.
