Stability Balance Disk :: Your NEW Bumpy Chair Cushion Disc :: Wobble / Wiggle Air Seat Disks also Best for Kids in Classroom Seating :: Because You Need the Top Adults Core Exercise Trainer :: Includes FREE Instructional eBooks :: Instant Lifetime Product Warranty

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!

I wanted a balance disk to help my back and try to strengthen my core. The physio thought it would help. So looking at all the reviews I picked this one. It comes with a pump and a few exercises on the back of the box. I have to confess it was the exercises that swayed the decision to pick this disk as there are loads of different ones on amazon. Anyway - the disk is great (I've already bought another one). I use it on my office chair, weaving bench and sewing stool. I got the second one as I'm currently not balanced enough to just stand on 1 - a foot on each disk is great for balance and core work. Unfortunately the "needle" on the first pump was faulty, but as I have another pump in the 2nd one I'm not bothered. I would recommend these disks - they are very sturdy and good quality. Although to be fair I have no idea what the competition is like 😄

Superb customer service! I had some trouble inflating this disk and in the process made a hole in it. King Athletic responded very promptly to my concerns and immediately dispatched a new one for next day delivery with no additional fee. The disk itself is very good quality, and the suggested exercises on the box a good challenge. I'm using it to strengthen my ankle following a running injury, but look forward to using it to strengthen my core as well. Just be careful when inflating it - the needle of the pump needs to go in quite deep to activate the valve, but obviously not so deep that it pops out the other side.

Not happy with the poor quality of the pump. My earlier review was taken down as I mentioned I wasn't happy with customer services.

The needle on the pump broke within two days of getting the disc. The disc itself didn't inflate properly at all, no matter how much air was pumped into. Not too pleased with the item to be honest.

I was suffering badly with PGP from about 25 weeks into my pregnancy. After speaking with my Physiotherapist they recommended I get one of these for sitting on. It was a fantastic purchase and with regular daily use my pain has been relieved dramatically. It is so handy because I can bring it to work with me and use it much more discreetly than an exercise ball. IT is also much more portable than an exercise ball which is convenient for bringing with me where ever I go. My nephew who had difficulty sitting still also loves this!

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.

As regards to the product, I'm very happy with it so far.I've also found seller very helpful.I bought three stability discs - one for me, one for my older sister and one for my mum. As you can imagine, our strength/fitness levels vary. However, we've all gained something from the discs and find them convenient and easy to use.So far, so good!

The pump that came with this was absolutely useless. We then used a ball pump, after sitting on it for a couple of hours it deflated. Worthless piece of crap. I can't believe we spent over $100 on this thing. What a complete waste of money!

This is my second King Athletic balance disk. I use it every day as a seat cushion.. mainly at work. I was diagnosed with chronic back pain & used to be at the chiropractor weekly. He recommended one of the balance ball chairs for me, but they were rather pricey. I found this & tried it as a much more affordable compromise. It's made an incredible difference for my back. I rarely have low back pain anymore. I took it in to show my chiropractor, & he was rather impressed with it too.My original disk went missing, so I had to do without one until this arrived. As a stop gap, I used the coccyx pad seat cushions that I used to use. Still, within a day, my back was achy, by the 3rd day, I needed to take a pain pill for the first time in months. Then my new (identical to my original) balance disk arrived. I dashed home at lunch to get it, & I felt an almost immediate easing of my lower back tension when I got back to work & began using it.I had my original King Athletic balance disk for months. After inflating it to the fullness that suited me best, I never needed to inflate it again. I used it for 8-10 hours every day. These are sturdy & retain their resiliency. If my original one doesn't turn up this week, I'll be sure ordering another of these very soon. I don't want to be without one again!As a quick side note, a coworker tried this one out when I got it. She sat down & promptly said, "I want one!"

***Disclaimer-First and foremost, I was asked to provide an honest, unbiased review as a product tester for “King Athletic”. To my benefit, I was on the market for an item like this, so the fact that this opportunity presented itself, it made me extremely happy and willing to participate in submitting my review. I believe accurate information is key for the success of products and services.Among KA, I own plenty of other equipment ranging from companies such as Rogue, Bosu, Reebok, Nike, TRX, Concept2 and etc.I own my own personal gym and have been in the training industry sporadically since 2011.***Today I will be reviewing King Athletic's Stability Disc.I received the package in a timely manner, with packaging still intact and a clean box with clear pictures on the back displaying the different movements possible on the disc.Within the box were the deflated disc, the pump and nipple, and the instructions on filling and using. The instructions on filling the disc with air are straight forward. DIFFICULTY WILL INCREASE THE LESS AIR THERE IS IN THE DISC! Once I removed the disc from the packaging I noticed thatOverall, this is a simple accessory and extremely beneficial to have in your equipment sets. It is affordable, made of good quality material, and made by a company that has proven excellent customer services skills (this isn’t the only product I own from King Athletics, and have had conversations with members on their team regarding products and information.NOTE: The disc works phenomenal to build proprioception (balance and stability on an unstable base) uni/bilaterally. It also works great as a seat cushion as its instability forces us to brace our cores to sit correctly, leading to better seating posture, and starting you on the road to improving your musculature imbalances overall.Well made with great use. THANK YOU KING ATHLETIC! PLEASE KEEP THE QUALITY COMING!Regards,-Rafael

Good product, and it does what is intended. There were some complaints from other users as it relates to indention's when blown up but that just means you blew it up to much. It is not meant to be blown up fully as there is suppose to be some give to provide the stability/balance aspect. That said my only problem with the disc was that the hand pump it came with did not have a threaded end which meant the needle provided would not screw in. Therefore had to use another pump. That said everything else was just fine

I bought this stability disk which I wanted to use on my chair at work and hoped for the best. As another reviewer mentions, it comes with minimal instructions but seemed simple enough. I used the pump and filled to the point it said to (until you can stand on it without touching the floor). I used it for a few minutes and realized it was slowly leaking air that was likely caused from the pump head puncturing the disk. Shucks. I decided to return it with a replacement. I received the replacement quickly and was excited...unfortunately, this one would only fill partially and no matter how much I tried, it wouldn't fill past the halfway point and appeared lopsided (see photo). My husband tried as well and got as far as I did which left a half inflated lump. Maybe I just got unlucky on this.
