The mifold is a variation of the traditional booster seat that folds up very small and easy to transport for travel or move for carpooling. Unlike a more traditional booster seat, however, the mifold does not "boost" children up, and into a seatbelt friendly position, rather it pulls the seatbelt down to fit the child as they sit on the vehicle seat. While the ease of transport is convenient, the crash tests results were some of the lowest in the group and the product itself is hard to use and hard for little ones to buckle around. Overall, it didn't fare well compared to the competition, and we feel the BubbleBum, another small and lighter weight booster, is a better choice for travel thanks to the better crash test results.
Pros: Portable, nicer quality, lower price
Cons: Lowest crash test results, hard to use, uncomfortable

Our Analysis and Test Results
The mifold booster was invented by Jon Sumroy after having children and experiencing the problems that inevitably arise with carpooling and having his children driven in other people's cars. Jon set out to create a small, tough booster seat that could easily be transported and moved from car to car that would still keep children safe and allow for three children to sit across in most back seats. They call the invention the "Grab-and-Go" booster, and it was officially released in 2015.
The following chart shows each booster tested in this review arranged by overall score. The mifold (in blue) earned the lowest score in the group.
The sections below explain in more depth the performance of the mifold compared to the competition.
The mifold earned a 3 of 10 for crash test results. This booster earned the lowest chest sensor score (g) and the third lowest head sensor score (HIC). The sensors in the crash test dummy record the forces to the dummy that result from the impact of the sled crash.
The front chest sensor (g) for the mifold recorded a 48. This amount of g's is above the average for the group of 44. The maximum allowed result is 60 to pass Federal guidelines. The lower the score, the better. No other product had more forces than the mifold. The Peg Perego Viaggio Flex 120 earned the best result for this sensor with a result of 39 (see chart above).
The head sensor or HIC score for the mifold is 733. The maximum allowed by Federal law is 1000, where a lower score is better. The Evenflo Spectrum has the lowest result (best) in the group with a HIC of 456. The chart above shows the results of the mifold compared to the Evenflo Spectrum.
Ease of Use
The mifold earned a 3 of 10 for ease of use. This score is the lowest in the review for this metric. The mifold is hard to use and keep positioned correctly with the lap belt retainers sliding in and out when you don't want them too. Adjusting the seatbelt positioner is also difficult, and our little testers had significant trouble buckling the seatbelt because the mifold bottom gets in the way of the buckle. Overall, the children in our tests struggled to use the mifold when they didn't have trouble with the competition.
The best thing about the mifold is its ability to be easily and quickly moved from car to car or carried in your purse for travel, and this is likely why parents are attracted to the product.
This booster is spot clean only, and there are minimal parts to clean.
Weight and Size
The mifold earned a 10 of 10 for weight and size. This metric is where the mifold shines. With a weight of only 1.5 lbs, it is the second lightest in the group after the smaller and transportable BubbleBum. This product is the smallest in the group with a width of only 9.4 inches. This width makes it ideal for fitting three across for multiple children and carpooling, and it makes it small enough to fit in your child's backpack for travel in cars other than your own.
The mifold earned a 2 of 10 for comfort. It lacks a true cushion with just a small firm base and relies on the vehicle seat for support, unlike the competition. The seat feels nice, but the anti-slip fabric isn't soft and still slips out from under kids while driving negating the reason for the less than desirable material.
The mifold earned an 8 of 10 for quality. This booster feels like a durable and quality seat there just isn't much to it. The seat bottom is thermo-molded with thin, firm padding and a slip-resistant back. The exterior is simple and easy to wipe clean with few places for gunk to hide.
