Should I Get A Waterbed Liner?

What about waterbed liners?

It's likely if you buy a bed it will come with a purpose made safety liner and hey it's a cheap insurance policy that will never be needed so fine.

But if you are building your own or trying to assemble a bed from various sources it's probably wise not to miss out on a liner at the prices these come in at.

At the end of the day a double skin is better than a single so I would opt for a liner even though I understand trouble is unlikely.
