The Inflatable Rubber Ring Cushion is a lightweight and compact comfort aid that is very easily popped in a pocket or a handbag so that it is always available when needed.When needed, simply blow the cushion up, either by mouth or by using a pump, and you\"ve instantly got a comfortable chair cushion or use it as a support for resting a broken or painful limb on to reduce the pressure and improve comfort. The Inflatable Rubber Ring Cushion is just as easily deflated for storage and can simply be wiped clean when required. A larger diameter version of the inflatable ring cushion is also available in this section of our shop.
