## Description

Your search for the best stability disc is officially over. When you buy the King Athletic Stability Balance Disc today, here's what you should do. The moment that box is dropped at your doorstep... don't wait, not even for a second. Rip it right open and take out the Stability Disc. It will be deflated but don't worry. Run your hands across its soft spiky surface. These little rubber bumps will soon be responsible for maintaining a firm grip when you stand or sit on the stability disc. Now, quickly inflate it using the free pump you've received from King Athletic. Put it on the nearest chair and sit still on it for a few seconds. Focus on your body and how it feels against the disc. You will start to feel your back and core muscles being engaged as your body instinctively tries to balance itself on the disc. If you feel more adventurous, put it on the floor and stand on it with one foot. Extend your hands forward at shoulder height and perform a lunge. Repeat a few times and you'll start to notice your glute and lower back muscles feeling the burn. The stability disc accelerates the result without you having to put in any extra effort during exercise. By now you are probably smiling, realizing you've got an exercise tool that will radically improve your life.The stability balance disc is your new best friend. You'll sit on it while working to relieve shoulder and back soreness, and use it at home to improve posture and exercise your back and torso. So get your wobble disc now. ...And when you do, why not get two? Your best friend will surely appreciate the gesture!

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great 'Wobble Cushion'!
*by M***. on 20 July 2017*

I am very pleased with my new King Athletic Stability Disk. I was recommended by my Osteopath to purchase a 'Wobble Cushion', as she called it, and after just one week of minimal use and very basic exercises I can already feel a slight increase in the flexibility of my back. It certainly helps to ease stiffness. It is surprisingly tough, well-made and easy to inflate. Great after-sales support too from King Athletic!

### ⭐⭐⭐⭐ Good for improving your core muscles and therefore your back strength
*by G***E on 22 February 2017*

I've been using the disk for a week or so now and would make the following observations:it definitely makes you sit up straighter as you have to counter the wobble,I would recommend heating it slightly before sitting on it, otherwise it feels cold to sit on,try to use it on a hard surface chair as you'll get the most out of the wobble.The pump works a treat, but put a bit of soap on the tip so it goes into the cushion more easily.Only 4 stars because some wally decided to put it in the post without sealing the box ends and the package arrived rather tattered. So, bad packaging (seller please note) but good product. My back and core muscles thank you.

### ⭐ it arrived today partially inflated so i inserted the needle ...
*by B***S on 20 March 2018*

it arrived today partially inflated so i inserted the needle and pumped it up however the needle bit bent and then snapped off! (and cut my thumb) ok i thought i still have the inflated cusion i just need to get a new pump! Not so, i sat on the cusion and it completely deflated and is now flat as a pancake!
