I'll be honest: I thought school was totally stupid back then. And as a mother, I find the whole thing even more stupid. For me, the fact that children sit for so long is the biggest flaw in the whole thing.
Well, I can't do anything about school, but I can do something about my child's good sitting posture: That's why I got the kiddo this super-smart desk from Lifetime, which is height-adjustable and thus grows with the child. The height can be adjusted from 56 to 78 cm. The top also tilts 0, 10 and 20 degrees to ergonomically fit your child.
The front bar always remains horizontal, and when the top is tilted, it creates an edge that keeps books and sheets in place.
A really smart piece of furniture that may not revolutionize school but certainly makes sitting more comfortable and healthy.
