“Perfect for travel: durable and very compact”
“Love this product! Bought it a few years back pre-pandemic. It is perfect for travel. Folds so small, to put into our carry-on pocket.”

We bought the seat to use on a trip to Disney World when we weren't renting a car and bringing my daughter's large booster seat with us. She thought it was very comfortable and felt like a big girl not having the large, bulky seat. Took 2 minutes to find the best sizing for her when we first bought it and then about 30 seconds to get her secured in it after that. Folds up nicely in the bottom of a backpack and was perfect to use on the few Uber trips that we had to do during the trip. Would highly recommend for use traveling.

“Perfect for travel: durable and very compact”
Our family is really happy with this design. Our daughter a very petite 11yo. Not only is this more age-appropriate, but I feel like it’s better than a traditional booster because it does more to actually make the seatbelt fit properly.

We planned a trip to Chicago but didn’t know what to do about our 6 yo’s booster. Real pain to lug in and out of cabs/Ubers (and what to do with it in shops/museums) but we didn’t feel comfortable going without. This was a perfect solution! Takes a minute to install, but is small enough to throw in a backpack/tote and light weight. Great purchase!

How does it work/compare to a regular booster?

A regular booster seat lifts the child to be in the position of an adult. Mifold does the exact opposite, instead of lifting the child up it holds the seatbelt down. It does this at three points: there are belt guides on either side of the child's hips to hold the lap belt correctly against the bones and off the soft stomach. These belt guides are adjustable to three sizes to make sure that the belt is always held snugly in place. There is a third clip on a strap that pulls the seatbelt chest strap down correctly onto the bones of the shoulder; away from the face and neck. So like a regular booster, Mifold holds the seat belt in exactly the correct position on the bones of the hips and the bones of the shoulder, without needing a big, bulky seat to lift the child. In a collision, the child is protected in the same way. Mifold simply works to hold the adult seatbelt correctly on a child.

Why should we use Mifold?

Mifold is a revolutionary car safety solution which is great for everyday use, but thanks to its compact portability can also be used on those occasions when a traditional booster seat is not available. Research shows that the correct child restraint is not used in about 25% of all child journeys (and that 50% of kids in the US don't have the right booster when carpooling for the school run). This is often because a bulky booster is inconvenient or unavailable. We want to eliminate these risks completely. With a compact and portable device, there are no excuses, a child can always be safe no matter whose car they are in.

How is Mifold the first innovation in booster seats for more than 50-years?

In 1963, Dean C. Hunter filed a US patent for the “Safety Seat” … a box that lifted up a child and held a lap belt in place across the bones of the child’s hips. Today, half a century later, boosters are essentially the same ... blocks that lift a child up to meet the adult safety belt. Mifold changes this. Instead of lifting the child up, Mifold does the opposite and holds the seatbelt down to fit the child. Our patent "Apparatus for adapting a seatbelt for a child" is already granted in one country and pending in 45 others (http://j.mp/mifold-patent).

In what colors is Mifold available?

Mifold Comfort is available in Charcoal Gray, Royal Purple and Ocean Blue.

Where is Mifold manufactured?

Mifold is manufactured in China. Our manufacturing partners are world renowned manufacturers that are ISO approved and operate at the highest level of manufacturing and quality control standards. They already manufacture child restraint products for several other well known companies.
