It proves ever so useful for how much it costs.
It may not be the best at being a pillow, but it's definitely a must have piece of bedding if you want to take a rest every once in a while on your bed without actually going to sleep. You can either put it under your head or hold it in your arms, meaning that it is very versatile.
It even contains a light quilt that you can take out to cover yourself while sleeping, a very useful addition to your bedding suite in summer days when it's hot.
