Fitness MadUnisex's 500Kg only-75cm Swiss Ball, Graphite, 75 cm

Packaging was OK and delivered in good time. Ball definitely has some sort of non slip texture to it. Managed to blow this up without a pump but you'll need good lungs and a good technique to do this. I'm 6'1" and my leg made a 90 degree angle when I sat which apparently indicates this ball is the correct size for me. 4 stars because the ball stuck to my wall paper when it was leaned against it.

We have a much cheaper model (cost £11) in the office and there is a clear difference.Use the max load as a guide... there is is no way the cheap ball could support this without bursting; the ball deforms a lot more despite being blown up to the same size.It may be a personal preference, however I prefer the firmness of this version.The look is also good, smart without being in-your-face, so the wife doesn't mind it lying about at home which was the aim.

Je l ai découvert chez mon kiné suite à un lumbago.Vu que j en fait régulièrement, j en ai acheté un et des que je sens des picotements dans le dos je fais les exercices de mon kiné 3 fois par jours pendant 3 ou 4 jours.Il me fait énormément de bien.

Mon métier m'oblige à couper de petits morceaux de métal. Certains ne manquent pas de tomber par terre et les balles usuelles n'y résistent pas.J'ai celle-ci depuis maintenant deux mois et tout va bien. Elle est de plus très confortable et ne se dégonfle pas. Cela vaut largement le petit supplément de prix.

I bought this ball to replace my traditional office chair. It certainly helps you to keep a good posture and prevents you from slouching.It's fun to sit on and bounce! I found that if you blow it up to its full diameter is not as bouncy, so if you wanna use it as chair size up...
