I purchased this to have as a backup for when I need to throw in my car for extra kiddos.... It did take a learning curve to get it open and set up. My daughter does say its not the most comfortable but it does the job and I don't use it as a permanent seat.

Fantastic! Easy to collapse. It feels a lot more safe then the origin hi fold but a lot better than lugging around a huge booster and just as safe

This seat is perfect for cars with multiple seats across without sacrificing safety. It will last a long time and makes it easy for children to access buckle themselves. Waiting for slate to be back in stock to order additional seats.
  • Sleek, light, side protection for crash
Best Uses

Nice option that is in-between a convertible car seat and a backless booster car seat

We have a Wayb Pico as the first travel car seat we got for our oldest kid, though we have not actually travel with it (partially due to the pandemic). Although it is expensive, we got the Pico when it first came out because I also wanted something small to fit in my Golf, and it is perfect. I was actually thinking about purchasing another Pico, but realized that our oldest kid already meets requirements of a booster car seat, and our 2nd one can sit in the Pico. So there is no need to spend that much money on a Pico. Since I was also thinking about traveling internationally to visit family in the near future, I began searching for something similar to the Pico and came across the Mifold HiFold booster. Needless to say it fits in my Golf perfectly right next to the Pico for everyday use. Although 2.2lbs heavier than the Pico according to specs, HiFold will last much longer since the Pico is only good up to age of ~6. The Hifold is very easy to fold and unfold that even without a manual you can figure out in no time. The only thing that takes a tiny bit of time and effort to do is to put the seat belt through the shoulder belt guide, but it is still very straight forward. The construction of the Hifold seems a bit... flimsy, BUT... I think that's because it is designed to be adjustable and lightweight rather than anything else. You can't really expect it to have the same steel frame as a full size 25lb convertible car seat with 5-point harness while maintaining only 40% of the weight and still foldable and being travel friendly. It does meet world wide regulations so it must be safe enough to use.

Can this be used on an airplane or is a shoulder belt required to secure it?
Just like all booster seats, you can't use the hifold on an airplane.
