On "Friends", where does Janice's husband work?

On Friends, Janice's husband works at the Mattress King.

The detail appears in “The One with the Race Car Bed,” the seventh episode of Friends season three. Janice's soon-to-be-ex-husband is identified through his mattress business, and Monica buys a race-car-shaped bed from the Mattress King store. When the wrong bed is delivered, Monica and Joey go to the store to return it and discover Janice kissing her husband.

The Mattress King is both the character's nickname and the name associated with his business. The episode uses the job as part of the comic plot surrounding Janice's marriage, her renewed relationship with Chandler, and the awkward discovery that she is still involved with her husband. Viewers sometimes remember the husband mainly as Janice's ex or as an unnamed businessman, but the show's dialogue and episode credits identify him through the Mattress King title. The answer refers to the business, not a conventional employer's personal name.
