This interior designer has dreamed up a mattress big enough to fit your entire family.

The Ace Collection $2,750 “family size” mattress is 144 inches wide by 80 inches long – which is almost twice as big as a traditional 76-inch-wide by 80-inch-long king, and more than twice the width of most cars.

And after mastermind Ana Pekarovic posted a pic of the 12-foot-wide, super-sized sleeper to Facebook on Thanksgiving, it grabbed 1.5 million views by Cyber Monday.

“It went nuts,” Pekarovic, 43, told Moneyish. “I’ve received hundreds of requests to buy them already, and thousands of emails.” The mattresses will begin shipping in early January.

While Pekarovic was decorating homes for 20 years, she noticed that many clients (including NFL players, retirees and growing families) were complaining that their king-sized beds weren’t big enough for them.

“People need more room,” she said. “Your kids jump on the bed to watch TV or read stories with you. Or other people tell me, ‘My dog and cat sleep on the bed, and I feel like I’m hanging off the edge.’ Nobody fits; we’re all crammed.”

But when she went to mattress stores looking for something a size up from a king, she was quoted prices as high as $10,000. “For a mattress, for God’s sake! This isn’t a car,” she said.

Then again, most people shopping for a mattress expect to spend $1,000 to $1,199, according to an HGTV survey. And prices vary widely across the $15 billion mattress industry because it’s common practice to make them up 40% to 50%, according to Consumer Reports.

So Pekarovic found that creating customized colossal beds with manufacturers she’d worked with over the past two decades was much cheaper. An entire Ace set, including mattress, box spring, bed frame and bedding, will set you back $4,054. The duvet or the bed skirt sold separately cost $850 and $330, respectively.

She was making them for her customers over the past five years before realizing last summer that she should mass produce them – along with the complimenting frames, headboards and bedding that would be hard to find in the right size otherwise.

“I noticed that a California king bed fits two king-size pillows, and decided the next size up (her 108-inch-wide Ace bed) should fit three pillows – otherwise it just looks sloppy – and then obviously next size up from that (144-inch-wide the Ace Family Size) should fit four,” she said.

And she named her mattress the “Ace” because, “What trumps a King when you’re playing cards?”

While she didn’t design the mega-mattress specifically for the 13.5% of parents who co-sleep with their kids, moms and dads are going gaga for it – which restoked the debate on whether it’s safe to share a bed with babies or not. (The American Academy of Pediatrics advises against it, since co-sleeping can increase the risk of sudden infant death syndrome.)

“This has nothing to do with co-sleeping; this has to do with providing sometime to my customers, because there was a need in the market for larger beds, larger bedding and larger frames,” she said.

Reisha Delug, one of Pekarovic’s regular customers, ordered the Ace Family Size bed over the summer to help her sleep through her second pregnancy.

“I needed a lot more space in the bed, so that was really helpful,” Delug, 32, told Moneyish. “I have a 3-year-old, and he obviously comes into bed once in awhile. And we have a Yorkshire terrier who’s always in our bed, too.”

Plus, her night owl husband used to wake her up by climbing into their old king-size bed after she fell asleep. “I swear, that extra space changes everything,” she said. “He really is able to sneak into bed now, and I don’t wake up nearly as much.”

But for those losing sleep over the Ace Family Size’s $4,000 price tag, there’s also the 108-inch-wide Ace mattress starting at $2,250, with full sets going for $3,274.

And Pekarovic said she is working with her manufacturers, whom she’s built relationships with over the past two decades, to continue bringing the price down, and to offer package deals.

“This is still a luxury item, but I wanted to make it more affordable,” said Pekarovic.

But customers like Delug say a good night’s rest is worth the $4,000 investment.

“You spend eight to 12 hours in bed – the most time in bed than anywhere else in the house – so it needs to be really comfortable and the right size,” said Delug. “It makes more sense than spending $2,000 on a couch that you maybe spend two hours on.”
