DS is 6. He starts year 3 in September at the junior school on site. (seperate schools). I have been very pleased with all I have learnt about this school and very glad DS is attending there. 
He did his trasfer day today and LOVED IT. 
So we're discussing school and he's excited about the independance they get -eg leaving hall when they've finished lunch, no asking or waiting.
I asked what else was different. He said 'we have to put our hand up if we want to leave our chair in the classroom, or our stool - I've got a blue stool'
Then goes on to say they were left when current yr 3's are moving up as some children swung on their chairs. DS says he has to keep the same place and will be having a stool.
Am I right in thinking this may be because he's figitty (he's not a swinger though).
Do they work in a similar way as wobble cushions as a kind of sensory thing - to aid concentration and core stability, which can then aid fine motor skills. (all of which DS is poor at)
The school is known for its high level of pupil support.
Or am I reading too much into it and he just happens to have a stool. 
Anyone know of a similar thing?
TIA
