What is the inset in the headboard? Suede? Leather? No brand stamped on the underside anywhere?

I'm interested in the queen size, so will be following this thread!

I'll have to take a closer look and report back. The inset on the headboard is suede microfiber. The frustrating thing is these pictures are actually from a craigslist post of my same bed frame, so I know these frames are out there somewhere.

Do you think it might be "vintage" Ikea? Thus the availability on CL? The slats look much more substantial than current Ikea, but maybe they used to be different?

Maybe call about the next one you see on CL and see if they know the manufacturer?

I don't think it's Ikea either. I tried emailing the one craigslist post I saw but unfortunately I got no reply. I checked Crate & Barrel and West Elm and they don't currently sell this frame, but it's possible they have in the past. Thank you for the link nosoccermom! I'm going to give them a call and ask if they know more. Based on their price point in your link I would be surprised if it is manufactured by C&B or West Elm. The hunt continues!

I called the store in the above link and found out the frame is made by Coaster Fine Furniture, but unfortunately they no longer make this frame. Too bad! Thanks for all of the thoughts!
