1 - Although California King is available in Canada, this size only represents a small portion of our king mattress sales.
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.
Square, rectangle, round, cut corners to fit antique four poster beds, we're well-suited to work with our manufacturing partners to provide these unique requirements. Our handcrafted luxury natural mattress range from Berkeley Ergonomics, Harrison Spinks, and t•masc (made in Ottawa by Obasan) allows for just about any possibility.
Our custom mattress category is an excellent starting point for obtaining ideas and approximate pricing on special sized natural mattresses.
Our partner suppliers are able to craft a mattress in just about any of these uncommon mattress dimensions. Be sure to check out our custom mattress category as a starting point to source these sizes.

About Discrepancies
It is normal 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. Depending on the mattress manufacturer, deviations of 1" or more may still be considered as within the acceptable tolerance.
