Its unstable surface requires you to use more central force, which helps you achieve better results in less time.

The Tumaz Wobble cushion is made from the thickest and most durable material on the market. The additional anti-burst design and non-slip matte surface provide a quality look and a high level of safety.

Giving children mobile seats is the easiest way to help them stay focused while sitting for long periods of time. The easiest way to maintain good posture.

If you have a big booty and are quite heavy, I find medium pressure is the sweet spot. **Q: is it latex free?** A: Yes, it is latex-free. **Q: Can you use this on carpet or the floor? Or is it better to sit on it while in a chair?** A: You can use it on carpet or on the floor, but I think it’s easier to use it on a chair. **Q: What is the weight limit?** A: It does not have one specific weight listed as a limit. But so far all my 4 kids and husband have used it. My kids weigh 100 lbs, 79 lbs, 67 lbs, 88 lbs and my husband is 245 lbs, it is still inflated and holding up well. We had to use an old pump we found because even though we paid for it and it says it comes with a pump it did not. Hope this helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Wobble cushion *by M***S on 18 June 2021* It’s wobbly that’s for sure, seems to handle the weight fine. So far so good. ### ⭐⭐⭐⭐⭐ 体幹鍛えれる？！ *by た***き on 18 October 2024* 椅子に置いて使ってます。体幹鍛えれてるかどうか、わかりませんが、座り心地は悪くないので愛用してます。耐久性もありいいと思ってます。使い方間違ってるかもですが。 ### ⭐⭐⭐⭐⭐ Angenehmes Sitzkissen für aktiveres Sitzen - bessere Körperhaltung *by P***E on 16 March 2026* Ich habe mir das Sitzkissen für den Einsatz am Schreibtisch geholt, da ich oft längere Zeit sitze. Bereits nach kurzer Zeit habe ich gemerkt, dass ich automatisch aufrechter sitze. Weil man sich immer leicht ausbalancieren muss bleibt man aktiver, anstatt komplett starr auf dem Stuhl zu sitzen. Mit der mitgelieferten Pumpe lässt sich der Luftdruck gut anpassen bzw. einstellen. Nach kurzem probieren, habe ich die passende Festigkeit gefunden. Die Oberfläche vom Sitzkissen ist rutschfest und das Material ist robust. Man kann das Kissen sowohl auf einem Bürosessel als auch auf einem normalen Sessrl verendet werden. Bei den Kindern ist es auch sehr beliebt, weil Sie die wackelige Sitzfläche ganz interessant finden. Insgesamt ein praktisches Sitzkissen für alle, die beim Sotzen etwas mehr Bewegung möchten und die eigene Körperhaltung verbessern möchten. ## Frequently Bought Together - Tumaz Wobble Cushion - Wiggle Seat to Improve Sitting Posture & Stay Focused for Sensory Kids, Balance Disc to Relief Back Pain & Core Strength & Flexible Seating [Extra Thick, Pump Included] - Chair Bands for Kids with Fidgety Feet, Alternative Seating in Classrooms, for Kids with Sensory ADHD ADD Autism and Sensory Needs - Trideer Wobble Cushion with Inflation Pump - Wiggle Seat for Sensory Kids(Multiple Colors), Balance Disc (Extra Thick) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/377529158-tumaz-wobble-cushion-wiggle-seat-to-improve-sitting-posture-stay](https://www.desertcart.jp/products/377529158-tumaz-wobble-cushion-wiggle-seat-to-improve-sitting-posture-stay) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-10-14*
