The owner, Zach Motl, used the Ikea MALM bed frame and simply put the headboard piece at both ends to create the chaise. It's only $89 as shown below, so I'm guessing if you buy 2 headboards instead it might be a little bit more.
Then you need a mattress to create the cushion. I personally would get the Ikea memory foam mattress so it has that nice boxy look like Motl's, but it would be super comfy to sit and sleep on. You could buy one of their spring mattresses for a $100 less too, but I would make sure it wasn't a thin mattress like Ikea used in the photo above.
And then it's time to make a cover for the mattress. I would make one or have one made that wrapped around the entire mattress with a zipper in the center, or velcro that would go underneath. And of course I would love a blue velvet, like the one I used on my sofa.
I also think you could get away without a lot of sewing by wrapping the mattress in the fabric and securing it underneath somehow. (I have some ideas in mind using elastic material and sewing strips that secure onto buttons). Other options for covers might be an extra large blanket or even a woven rug - you can get really creative.
Then make some bolster's like he did, or I love this gold dot pillow from Caitlin Wilson that would be amazing with the blue velvet or the stripe.
I love the round bolster pillows. I am seriously considering this hack for my own home, but mine would go in my basement family room and I would do a really fun fabric on the cover, because I could in that space. And how great would this be when my kids have a sleepover and need an extra bed! The ideas keep coming :)
