1 - Although California King is available in Canada, it represents a tiny fraction of king beds sold here.
Nearly all mattress sizes are rounded up. For example a Twin bed in real-world dimensions is usually 38 x 74" or a Double is 53 x 74". Queen and King are almost always 79 inches long. Most mattresses today are still primarily hand made, which will always lead to variances. Foam mattresses tend to adhere to sizing guidelines more accurately than spring mattresses.
The Mattress & Sleep Company is able to source many of these uncommon sizes. Those which are available online will have a link to their corresponding category showing the models available. For sizes without links to products, please call us on 1-877-750-1212 to learn more about availability and pricing.

2 - 36 x 72" was a common size in the middle part of the 20th century. It is no longer a standard size.
3 - California Queen was used primarily as a replacement for wood-framed water beds and is nearly obsolete.
The vast majority of queen size mattresses found in recreational vehicles are actually 5 inches shorter than a standard queen. From March until August, The Mattress & Sleep Company regularly stocks this size in our Springwall Ginger RV Mattress, a pocket coil model model.

Standard kings will sometimes be referred to as Eastern King. One instance of this will be with Wesley Allen iron beds. It is important to know which type of king you prefer. Although the extra length of a California King is nice, it may be harder to find linens and bed frames that work with this size.
Note that in terms of area, an Eastern King is the largest size available with a total area of 6,080 square inches. A California King has a total area of 6,048 square inches.
It is not uncommon for a particular mattress to not match up exactly to a size listed above. As many aspects of building a mattress are still done by hand, there will always be variations in sizing from one mattress to the next.
Often times, mattresses may measure as much as one or two inches shorter or narrower than the "official" dimensions. This is considered normal.
