Stays in place

This alternative seating option for classrooms, offices, and home use helps to keep the mind engaged as the constant ball movement increases blood flow to the brain.

  • Kids use these at school and love them!

    A***m on Nov 04, 2023

  • Follow the directions. It works perfect. When the kiddo isn't using it - it holds my hefty hiney.

    S***m on Aug 10, 2023

  • I teach first grade and ordered the small based on the size rating. If I ordered them again, I would order the medium ones. The smalls are a little small for my first graders. However, I loved that they already came with sand in them and were easy to air up.

  • I bought this for my son for use while doing remote learning at home. He found it fun but also helped him to focus.

    R***d on Aug 18, 2023

  • Just what we needed. My son can not sit still and has a special seat cushion at school. Now that we are doing school at home, we needed something and this ball is great! We got the small and it is perfect size (7 yo). The stuff inside the ball makes it heavy and sturdy too.

    T***m on Aug 04, 2023

  • Best medicine ball I have ever used as a chair. I use it in my office and sit on it for 10 hours a day. It has been a game changer for me!

    B***y on Jun 27, 2023

  • I use this as my desk chair. It helps me sit up straight an use my core more. I blew mine up bigger than the ribbon they included -the ribbon is a great feature though!!

    R***a on Jul 31, 2023

  • I bought these for my classroom for flexible seating. The sand inside does keep these in place, which is awesome. The color is beautiful. Once this pandemic goes away for good, I’m definitely purchasing more for my kiddos to enjoy!

    M***a on Nov 15, 2023

  • I have been using a yoga ball as a desk chair for myself for years. But I hated that it rolled away every time I got up. I love that this ball is weighted and eliminates that problem! I got one for me and one for my kids to use for homeschooling. This size S (45cm) is perfect for my 48" 6-year-old. Can't wait for mine to get here!

    C***e on Oct 22, 2023

  • My daughter LOVES this. We have modified and she uses it for her feet because if she sits on it at our standard desk, it is way too short. Still helps get her wiggles out and she uses it when we she does school work not at her desk.

    N***k on Aug 17, 2023

  • Great for e-learning at home. Kid sometimes falls/rolls off ball but he finds it hilarious and gets back up. Can be distracting though. Kid has trouble sitting properly in chairs do that's why we chose this.
