Therapy balls are great for kids who need an alternative seating option. Students need to be alert in order to balance their weight on the ball. I also use the therapy ball to provide proprioceptive input (deep pressure by rolling it firmly over a student who is laying on the carpet). A therapy ball can also be used for students who need vestibular input (rocking back and forth or bouncing).
I typically use these with my "wiggly" kiddos. Wiggle seats can give some of the same input as the therapy ball but are easier to implement in the classroom (especially in the general ed room) because they are smaller and don't stand out as much. There are a lot of varieties and textures. Last year I had a student who needed something to do with his hands when he was trying to focus but was easily distracted when given a fidget and didn't like using a fidget in general ed. Sitting on the wiggle seat he could rub the texture and it was more discrete and less distracting.
I have a student who is unable to sit "criss-cross" on the carpet because he doesn't have the needed core strength. Additionally, he struggled with boundaries and would often be turned completely around by the end of activity. At first he used a preschool cube chair but I wanted something to help him sit on the carpet like the rest of the kids. The howda hug has been perfect for this. It provides a backrest for core support as well as a boundary.
Like a therapy ball, a T-stool requires focus to balance. I have used the T-stool for those students who have not had success with a wiggle seat or therapy ball. A lot of students get frustrated at first with the T-stool because they are hard to sit on but when used correctly (intermittently with breaks) they work well for helping kids focus.
A rocking chair can be a way to provide calming, vestibular input and give students a break.
Bean Bag Chair
A bean bag chair is a great place for a student to take a break and listen to music or read a book. The “hug” of the chair around students can provide some deep pressure input and for students who struggle with sitting due to weak core strength it gives their body a break too.
