Really disappointed I've had to return this as the ball and cover are completely the wrong size for each other. I ordered a 65cm ball and cover. The cover is labelled 65cm but it must be 75cm because it fits neither the ball it came with nor the 65cm ball I already own. The ball it came with is actually smaller than the ball I already have so the sizing for both parts of the order is completely wrong.The cover itself is lovely and exactly the colour I need for the office space in my living room. Unfortunately, Amazon offers no way to contact the seller so I can't even request an exchange for the correct size. Have had to request a refund.Another flaw is that you have to inflate the ball inside the cover, so I've now inflated and deflated two balls just to establish that it is not fit for purpose. I've also got to try and get all the air out of the ball that was sent in order to fit it back in the box to return in. A complete waste of time and very disappointing.

Bought this to replace my broken office chair as I’d used one at a meeting a few times and found it helped my back. I’m hoping that the ball will inflate more as the cover is a little loose and also noticed the air needs topping up after being sat on it for half a day. At the end of the day it’s just a yoga ball with a nice cover so if I had to buy again I’d probably go with a cheaper option.

Absolutely love it! comfortable and a cheeky break for sit-ups during the working day. Everyone that has seen and tried it now wants one! :)

Stylish and useful, I have decided to buy this after seen a yoga ball used as offices chair in Switzerland. Read up online about it and purchase this product as i couldn't deal with sitting on my office chair for 8h a day anymore.Inside the package: the inflatable ball, the cool cover, and the pump.I mean, the pump is a bit basic so after a bit I decided to get my electric camping pump out.The ball need re-pumping top up every few days if you sitting on it for very long time.If I could suggest an improvement, please add the size charter on the pictures as there are different size for different heights. ( I had to re-search this on a different website before selecting the size of this ball)

It looks great, it really does. The ball comes with it and fits very well from the first go (just be careful not to over-inflate as the zip won't close otherwise).My gripe with the ball is the fact that it naturally wants to roll from most positions, probably because of the ridges that make up the panels. They're not noticeable to sit on, but they're enough for the ball to roll. This means that when sitting on it, unless you've positioned it just right, it's always pulling in one particular direction. Not so bad initially, this quickly becomes incredibly annoying as you find yourself either fighting with the ball or having to carefully reposition it every time you get up.Given that the reason I got this was to help keep my hips moving throughout the day, it's frustrating because the act of moving about on the ball seems to cause it shift position a little and go off-centre again. I'm now on the lookout for a cover that doesn't have ridges!

I bought a ball for my back some time ago but used it very infrequently. The noise of the plastic squeaking as I moved was not great in the office. But my back was still bad, seizing up from sitting all day at the computer. So I decided to give this ball a try and it really is perfect. The cover is comfortable and, happily, noise free! And my back is so much better too agree just a few days!A recommendation, the zip is impossible to do up if the ball is fully inflated. I easily got around this tho by partially inflating, then making sure the valve was situated just underneath the very last bit of the zip,and then doing the zip up leaving that last bit undone so that I could fill the ball up completely. Once done you can do the zip up fully. Hope that helps..

It's great and looks super smart in our lounge. I use this for work to help my posture, and it does. The only downside is having to re-pump it every 2 days. I don't think my weight is the issue at 65kgs and 5'6". That is the only negative. I love everything else about it.

I bought two of them, red and Orange, in both case s ball was to small for cover! Cover seems like 75cm and ball 65cm. I had to return both.
