When your kid has outgrown a harnessed car seat but still legally needs a booster, hauling a full booster through airports is miserable. The mifold is the answer a lot of flying parents reach for, because it is the smallest travel booster seat you can buy… it folds down to about the size of a hardcover book and disappears into a backpack. We bought ours, we actually traveled with it, and I want to be honest about how it went, because the reviews online are rosier than my experience.
What the mifold actually is (and is not)
Here is the thing to understand first: the mifold is not a booster your child sits up on. A normal booster lifts the child so the car’s adult seat belt crosses their body correctly. The mifold does the opposite… it stays flat and pulls the lap belt down and routes the shoulder belt in, so the belt fits a small body properly without raising them up. That is a clever idea, and it is exactly why it packs so small. It is built for kids roughly four years and up who have genuinely outgrown a harness.
How the mifold actually worked for us: fiddly
Here is my honest travel booster seat review. I found the mifold genuinely fiddly. Every single install you have to thread and clip the belt through the guides and get the positioning just right, and it is not intuitive… it takes a minute of fussing each time, and if you do not get it exactly right it is not doing its job. With a tired kid in the back of a rideshare, that friction added up fast. I personally did not love using it.
The Asia reality: often a moot point
We were traveling around the world, and here is what nobody tells you: in a lot of the places we went, especially across Asia, the cars simply did not have seat belts in the back at all. A belt-positioning booster does nothing if there is no belt to position. So the mifold ended up being dead weight for big stretches of the trip, and we stopped carrying it around the same time we stopped carrying our travel car seat, for the same reason.
Who the mifold is actually good for
I want to be fair, because it is not that the mifold is bad… it is that it fits a narrower situation than the marketing suggests. If you are traveling around the US and flying, and you will be in rental cars or rideshares that have normal seat belts, the mifold is a reasonable way to keep an older kid legal and safe without lugging a full booster. For that exact case (domestic trips, belted cars, an older child) it does the job and takes up almost no space. That is a real, genuine value.
But if you are headed somewhere the cars may not have belts, or you just want something quick and foolproof, this is not the one.

FAQ
Is the mifold FAA approved for airplanes?
No, and no booster is… boosters are not used on the plane at all. The mifold is for cars at your destination. On the plane your child rides in the airplane seat with the lap belt, or, if they are small enough, in an FAA-approved car seat or the CARES harness.
What age and size is the mifold for?
Roughly four years and up, for kids who have genuinely outgrown a harnessed seat. Check the current model’s exact weight and height range before buying.
Is the mifold hard to use?
Honestly, yes, at first. The belt-routing takes fussing to get right and it is not as quick as dropping a kid onto a regular booster. It gets a little faster with practice, but it never felt effortless for me.
Would you buy the mifold again?
Probably not for how we travel, but I would not talk a US-based flying family out of it. It is tiny, it is cheap, and it keeps you legal in a rental car.
The verdict
The mifold is the smallest, most packable travel booster seat out there, and for a family flying around the US and hopping into belted rental cars, that packability is a genuine win. But I will be straight with you: I found it fiddly to install right, I did not love using it, and once we hit countries where the cars had no seat belts it became dead weight. If you want legal booster coverage that fits in a backpack for domestic trips, it earns its spot. If you want quick and foolproof, look elsewhere, and see our full lineup in the best travel car seat guide.
