“Originally started with a smaller 34cm cushion but found it limited in use so opted for a bigger one. This one was competively priced & arrived speedily. Although no instructions or pump came with it it was soon inflated & has been used daily ever since with no problems and definite benefits to my balance & overall fitness. I would recommend this item to anyone wanting to improve their fitness”
“I needed this for balance exercises ordered by my physiotherapist to strenghen leg muscles: This didn't work for me: when blown up it was either too round, or not pumped enough to stand on!”
