The new parents treated themselves to six of the special-edition luxury beds by a company which supplies the plush Savoy Hotel in London.
The beds, costing a staggering £125,000 each, will take pride of place in their $11million mansion once they move in, says the Mail Online.
An incredible amount of craftsmanship and 604 hours of labour goes into each cosy creation, made from Latin American horse tail, Mongolian cashmere and 1,600 miles of woven silk thread.
They are thought to have splurged on the limited-edition Savoir Royal State Beds as part of the major renovation works going on at their new family home where they will raise their baby daughter North West.
The beds will bring a touch of British heritage to their lavish retreat in the LA suburb. They were from a limited collection of 60 made to honour the 60th anniversary of the coronation of the Queen last month.
The haute luxe bed company's celebrity fans include Madonna, Kylie Minogue, Elton John and Oprah Winfrey.
Recently, the couple are said to have glammed up the bathrooms by spending just shy of half a million pounds on four gold-plated toilets.
The new parents are also thought to be sprucing up their kitchen with a sparkling Swarovski-encrusted fridge freezer and almost $1 million worth of state of the art Electrolux appliances.
"They expect the interior to cost twice as much as the property. They're spending more than a million on a security system alone," a source told The Sun.
Facilities will also include a hair and makeup salon, bowling alley, indoor and outdoor pool, basketball court, cinema and custom gym, according to TMZ.
While Kim has kept an unusually low profile since giving birth to her baby daughter, Kanye has been spotted furniture shopping in Beverly Hills for their new nest.
The couple bought sumptuous mansion together at the start of this year, but have yet to settle down and move in.
After the release of his sixth studio album in June, Kanye has had more time of late to prioritise his family's needs.
Kim, Kanye and their little girl, who they've nicknamed Nori, are currently said to be living with Kris Jenner, Kim's mother and manager, in her Calabasas mansion.
