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'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 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!

This disk came partially inflated and so only needed a few pumps from the air pump (provided) to get it to the level I wanted. I use it all the time now, from sitting on it at my computor or watching Tv to doing my core excerises on. It is robust and withstands my 11 stone wobbling on it easily. My initla reason for the purchase was to strengthen my core for my running. Now I can do this in small bursts without interrupting my other activities or getting a large piece of equipment to take up space in my house. Also very good for a little boy to keep him sat still!

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 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 😄

So I wanted the stability disk for my Springer Spaniel who ihas arthritis and has started limping badly, it was recommended by his Physio. So we use the disk to do doggie press ups and he can stand on it and it makes him use his arm much more. It arrived blown up enough for the dog. However we had really clear instructions on how to use the pump? It is really sturdy and has not been effected or punctured by clawsI, it-arrived in really good time and good illustrations for human exercises.

It has really helped my back and is a great product. I would recommend it to anyone who has back pains or is just looking for a good way to exercise, I tested all the activities on the box and they are all easier to do but still give the same burn and results that you would get without the stability disk. My only criticism is that press ups were nearly impossible because when I pressed my hands against it they went diagonal making it much harder to do the press up. All round its a good product.
