1 - Although California King is available in Canada, it represents a tiny fraction of king beds sold here.

2 - Super king sized mattresses are available from Vispring, makers of hand crafted pocket spring mattresses since 1901. Super king bedding including sheets and duvets are available from St Genève, Canadian luxury specialists.

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.

Custom Mattresses

Square, rectangle, round, cut corners to fit antique four poster beds, we're able to source many of these custom mattress types. Our hand crafted luxury natural mattress range from Berkeley Ergonomics, Green Sleep, Sleeptek and Vispring allow for just about any possibility in both natural rubber, and pocket spring.

A Note on King Size Mattresses

Standard kings will sometimes be referred to as Eastern King. 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.

The Mattress & Sleep Company offers a substantial selection as nearly every one of our brands offer both varieties of king.

Note that in terms of area, an Eastern King is the largest common size available with a total area of 6,080 square inches. A California King has a total area of 6,048 square inches.

Finally, a Super King mattress from Vispring is pure luxury with a generous 7,225 square inches, nearly 20% larger than a standard king.

RV Queen Size Mattresses

The vast majority of queen size mattresses found in recreational vehicles are actually 5 inches shorter than a standard queen.

Those seeking a luxury mattress upgrade for their motor coach may wish to consider Green Sleep. This Belgian mattress maker hand crafts their beds to exacting qualities for discerning tastes. Green Sleep will custom make nearly all of their models to almost any rectangular dimensions required.

Please visit or call our Edmonton location for pricing. Our showroom also features an array of different mattresses available in RV size.

About Discrepancies

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.
