"It's one of those products that's truly an experience," said Blessed Little Bungalow's Amber Guyton. People love how oversized and comfortable it is. 

It helps that they may have seen it and sat on it in person. Diners at RH's rooftop restaurant have to first make their way through the showroom. "The Cloud Sofa's everywhere," said Guyton. 

And it is as comfortable as it looks. "It is like sitting on a cloud," said Studio London Co.'s Travis London. "I mean, the sofa is basically one huge pillow." 

The deeper seat and 18.5-inch height of the Cloud Sofa's cushions might not be for everyone, said Guyton. 

"The female clients I have, they don't wanna feel like a little kid with their feet dangling off the sofa," she said. People with mobility or joint issues may want something higher and less deep as well.

Then there's the white or linen color you often see on the Cloud couch. "You definitely have to be mindful of that with shedding pets and kids and markers and all of that," said Guyton. If you're looking for an everyday sofa, you might want to go with a darker color. Otherwise, you may end up with a comfy couch you don't actually feel comfortable sitting in, she said. 

London said mimicking the pillows is the most important future. "It has huge pillow backs" with down filling, he said, so if you want that softness, that's what you should look for.

If you don't want to get a whole new couch, you could look into new pillows for your existing one instead. "By doing that, you are adding more of the bounce factor and the comfortability," said London. "So that is a great way to do it on a budget." 

More generally, though, London said he likes his own RH sofa because it's lasted a long time, and he's updated it with new fabric as his tastes change. "If you have good bones in a sofa, you can constantly reupholster the sofa throughout its lifetime," he said.
