Cal King Waterbed Insert

I am looking for a Cal King Waterbed insert mattress. l live in Southern Ontario, Canada.

Hi doctordog,

Post #8 here has a list of some of the better options and possibilities in the Southern and Southeastern Ontario region and post #13 here includes some of the better options in the Southwestern Ontario Windsor area. Most smaller manufacturers and some retailers that have direct relationships with the factory can make a mattress that is custom sized although California King is a regular size with most mattresses and would be available with most models.
