Cushion 18" x 18" (45.72 cm x45.72 cm), is gently used and in excellent condition. There are many practical uses for this cushion. It can be used for any sitting activity, such as while driving, in a wheelchair, at the office, attending sports games or theatre, at university, etc. The cushion is great for medical conditions, to prevent pressure sores and alleviate pressure when and where needed, for example during treatment for Prostrate Cancer, hemorrhoids, etc. I have seen the Shear Smart Cushion sell in the USA from $105.00 - $153.56 US ($139.00 - $203.25 Can) The only real difference between this cushion and those sold new, is the warranty and this cushion has been used a few times. I have included, in the photos below, the description and some info from the company who makes the cushion. Asking $60.00 obo
