About Mifold
Why We Made Mifold
Jon Sumroy created the mifold Grab-and-Go booster seat after noticing how often kids rode in carpools unprotected. As a father of three, he wanted a compact, portable, safe solution for busy families.
Fueled by a record-breaking crowdfunding campaign, mifold has grown from a personal need into a trusted, life-saving tool for families and emergency responders worldwide.
At Mifold, we're redefining car safety for families on the go. Our mission is simple: to make car booster seats safer, more portable, and easier to use for families everywhere.

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.
