Review on Tumaz Wobble Cushion: The Ultimate Solution For Improved Posture, Focus, Pain Relief, And Core Strength by Justin Coatsworth

I actually been wanting one of these for a while because my coworker has one, so i decided to give it a try and see how good it is. Turns out it really does help alot. The way how its design makes you realize how you is sitting is wrong and need to adjust to the right position. As for when you do abs, or core workout, your arm is on this wobble cushion so its less painful than on the floor. You can really feel the quality used to make this product, so far it hasn't burst yet so im happy for now haha. Hopefully its forever anti burst. Also perfect for people who do yoga as well! Overall a awesome product to get if you trying to do core workout or have a better posture. Recommended!
