Review by:
"My husband wanted a soft and lightweight cushion to take to the Clipsal 500 for the 4 days as the seats are hard to sit on for long periods. And we've used the thermaRest self inflating seat cushion on many occasions. Its currently being used on my husband's computer chair, have used it at BBQs. It is very easy to deflate and very lightweight to carry. Also I found the website easy to use, prices are competitive, plus there are many items that are very beneficial for many health reasons that I was not aware of." (Posted on 6/07/2016)
