It low hight.  We have been looking for a low one off & on for twenty years.  This one adjust from the bottom which is good.  The first one we had was low & we used a small screen in the 70 s - 90 s which worked fine then.  We got a larger 27" screen & the newer tables were 28" high which required a short person to always have to tilt their head up more & use their by focals more often or buy a pair of glasses just for the computer.  It would serve well for a child as it could be raised as they get taller.
