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 hand crafted luxury natural mattress range from Berkeley Ergonomics, Harrison Spinks and t•masc (made in Ottawa by Obasan) allow 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.
If you're looking for a comfortable and affordable custom cut foam mattress, look no further than our Paarizaat custom-size gel memory foam mattress.
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.

General Availability Advice
The Mattress & Sleep Company is a family owned and operated business based in Alberta, Canada. We specialize in high-quality bedding, bath and mattresses from Canada, Europe and the USA. Our vast selection makes it impossible to stock everything. For this reason, our website does not offer real-time inventory availability as many of our products are made to order.
Please read the availability details above as we do make an effort to draw attention to products which are typically in stock in our Calgary, Edmonton, and Sherwood Park stores or our local warehouses.
For time-sensitive needs, please give us a call toll-free on 1-877-750-1212 or send us a message and we will be delighted to help.
