“A good night's sleep is truly a vacation in itself,” states a Bellagio online advertisement for bed mattresses that customers can purchase, complete with a Bellagio label, from the Las Vegas hotel and casino.

But evidently Bellagio management has been losing sleep over alleged trademark infringement.

According to a Las Vegas Sun report last week, the unit of MGM Resorts International has filed a trademark infringement lawsuit against Italy-based Magniflex S.P.A. for selling a mattress it named the Bellagio.

According to the website for New York-based Magniflex USA Ltd., the company is one of Europe's largest foam mattress manufacturers and distributes its products internationally. Aside from retailers, Magniflex also provides its products to hotels, which can put their own label on them.

But beds for the 3,933-room Bellagio are manufactured by Hoffman Estates, Ill.-based Serta International. Guests can purchase a Bellagio-branded mattress at a retail store in the resort or through the company's website.

According to the newspaper, Bellagio's lawsuit alleges that “Magniflex announced its Bellagio mattress long after Bellagio began selling mattresses and after Bellagio filed its trademark application for the Bellagio marks for mattresses.”

The lawsuit further states that Magniflex's use of the name Bellagio is likely to confuse or deceive customers. Magniflex could not be reached for comment.

Perhaps the companies can settle this with a pillow fight.
