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.
Carefully crafted and perfected, this luxurious mattress features sumptuous natural and sustainable fillings working in harmony with multiple layers of superior springs. The Northumberland features 15,000 innovative springs in queen size, including 100% recyclable, sustainable glue-free, Quad-core pocket springs and contouring Micro springs offering responsive support night and night.
Northumberland features 7 total layers of individually wrapped, glue-free pocketed springs. The result is a deeply cradling, sumptuous comfort.
Harrison Spinks is a unique offering in the world's foam-free luxury mattress market. While made using traditional methods of construction, the spirit of innovation which originally birthed the pocket spring is alive and well. Harrison Spinks not only produces their own springs in-house but the machines that produce the springs were also designed in-house. In order to achieve the remarkably thin gauge steel required for the world's highest spring counts they must run the steel through their own series of dies. The end result is a more elastic and supportive mattress, Micro springs will continue to offer years of resilient support even in the context of the natural fillings compressing. The value for money is unrivalled by their luxury competition.
So too, is the case with the entirely-natural foam-free fillings. In 2009, Harrison Spinks purchased Hornington Manor, where they operate a 300-acre farm. They rear prize-winning sheep and grow their own hemp and flax. In fact, Harrison Spinks is the UK's largest hemp producer.
Harrison Spinks mattresses are circular by design. Using only the finest in natural and sustainable materials, 100% recyclable at the end of life, to ensure zero landfill waste.
Harrison Spinks is proudly recognized as one of the world's best bed manufacturers and hold numerous Queen's Awards in areas such as Innovation, Sustainability and International Trade.
