The queen-size piece is among hundreds of items from the Holmby Hills mansion where Jackson spent his final days, which are set to hit the auction block in the US on December 17.

"We want to preserve the history of these items," said celebrity auctioneer Darren Julien, president of Julien's Auctions, which will sell the various antique furnishings, paintings and sculptures that surrounded the King of Pop as he prepared for a series of comeback concerts.

The Holmby Hills home where Jackson lived with his three children from December 2008 until his death on June 25, 2009, is separately up for sale.

A note from one of the children remains on a chalkboard inside the home's sprawling kitchen, where three barstools were lined up against the centre island - a perfect breakfast spot for the kids.

"I (heart) Daddy. SMILE, it's for free," the chalk note reads in childlike scrawl. The chalkboard will be sold as-is, and is expected to fetch more than 400 dollars.

At the very moment on Monday that Dr Conrad Murray was convicted of involuntary manslaughter in Jackson's death, reporters were eerily taking a private preview tour of the three-story home where the pop star lived and died.

The bedroom shown in evidence photos at Murray's criminal trial was considered a "medication room" by the Jackson team. Murray was found guilty of supplying an insomnia-plagued Jackson with the powerful operating-room anesthetic propofol to help him sleep as he rehearsed for his comeback.

Jackson maintained an adjacent bedroom that he regarded as his inner sanctum - a private place only for him.

It is in this second bedroom that the pop star wrote a message to himself on the mirror of an antique armoire. "TRAIN, perfection, March April. FULL OUT May," it reads. The star was to begin his London concert run in July.
