In the spirit of both San Francisco and sleeping well, locally owned McRoskey Mattress Co. rolled out a new mattress size guide last month, the 7-by-7-foot San Francisco king - a foot wider than a standard California king.

While McRoskey has always had the capability to make larger sizes for custom orders, a growing demand for bigger mattresses sparked the idea for a permanent line of supersize mattresses, says Robin McRoskey Azevedo, president of the 113-year-old company.

"We try to capture it with the tagline: more space, more comfort, more fun. It has some real value with people, families all piling into bed together and enjoying that space," Azevedo explained.

The 7-by-7 version is offered through two McRoskey lines: the Classic and the newer ByDesign.

Both have the same innerspring unit constructed with steel coils laced together with steel spring helical wire. Where they differ is filling material and price.

The Classic mattress is filled with cotton and polyester fiber and costs $7,777 for mattress and box spring.

The ByDesign natural mattress is filled with wool (sourced locally from a 100-year-old Northern California sheep ranch and carding mill) and a natural rubber latex filling. It costs $11,777 for mattress and box spring.

Mattresses come with a set of cotton percale sheets and two king pillowcases, waterproof mattress protector and a cotton mattress protector pad.

The name is both the mattress' dimensions and a reference to the dimensions of the city in which it is made.

"Seven by seven is a fun way to get a good product across," Azevedo said. "We're very local. We are a San Francisco company."
