How old can a child use airplane seat extender on a plane?
When choosing kids' airplane seat extenders, parents will wonder is it their child old enough to use the product, and whether this kid's footrest hammock is suitable for their child.
Quick answer: We recommend 2-6 years old toddlers use Gnegni kids' airplane seat extenders. And we will explain the reason from several aspects.
It is related to the seat pitch.
The length of our kid's airplane seat extender can be adjusted according to the needs, but how long it needs to be adjusted is related to the seat pitch. Seat pitch is the space between a point on one seat and the same point on the seat in front of it.
According to SeatGuru's data, the seat pitch of the economy class of an airplane is generally between 28"-38", which means that children whose height is within the range of 28"-38" can lie completely down when using the kids airplane seat extender.
It is related to the children's height
According to the children's growth chart on the Children's Wisconsin Site, the average height of 2-year-old children has exceeded 28". If the plane has a wider seat pitch, children aged 2-3 can easily lie flat on it. However, if the child is between 4 and 6 years old, the child's airplane seat extender cannot be used to lie flat. He needs to bend his knees and sleep in the fetal position, or he can sit and sleep, and elevate his legs on a toddler airplane seat extender.
Thus, considering the seat pitch, the average height of children, and comfort of use, we recommend kids airplane seat extenders for children aged 2 to 6.
My child is over 6 years old, is he still can use Gnegni kids’ airplane seat extender?
Yes. He can still use our kids airplane seat extender if he want.
According to the calculation of sciencedirect.com, the height of different seat pitches is 44cm (17.32''), which is the length of e in the above picture.
If the child's length below the knee is less than 17.32'', the child's feet will be suspended in the air, so it will not be very comfortable and it will cause poor blood circulation sitting for a long time.
According to the NCBI survey, the average knee height is 30.5% of the height. If the seat height is 44cm ( 17.32''), then a child with a height of about 144cm (56.7") and about 9-10 years old child's feet can touch the ground.
So if a child is about 7-8 years old, he can still use Gnegni kids airplane seat extender to help him elevate his feet.
In short, for children aged 2-3, the kid’s airplane seat extender is like a portable children's travel bed, he can sleep in lie-flat position completely, for children aged 4-6, he can sleep in the fetal position.
For older children, such as children aged 7-8, although the kid’s airplane seat extender cannot let them lie down completely like a bed, it can raise their legs and make their journey more comfortable.
