Create and Barrel had some a short while ago. Look them up on the web.

Someone was watching divine design

West Elm also has one.

For a more modern look (probably not what the original poster wants, but if anyone else is interested), there's the Blu Dot Nook bed.

Williams Sonoma Home has one as well.

Overstock has one at a nice price.

Sorry the Overstock Leann bed is ultra suede not leather. They do have leather beds without wings.

Sarah Richardson has designed a wing-chair-bed-frame. I'm not sure where you can find it.

This is my fav... It's on my must have list! I would get it in bark velvet. De-lish :-)

I just bought the one pictured here (stanley Louie Louie) about 3 weeks ago and we absolutley love it. It is very well made and the color is very nice. It sits very high with the mattress so mught not be good for someone that is short (I am 6'5" and my wife is 5'0"..lol.) She has to climb into it but still loves it. We bought it through Cymax stores. They delivered quick (free delivery and set up).

Stanley funiture has 2 or 3 more upholstered beds that are nice.

Good luck.

loving reb right now. knowledge with a little sarcasm. thanks.

If you saw it on Divine Design, it may have been this bed:

I was looking for this kind of bed forever in wood. I ended up with this bed from a company called Zocalo. It's not leather, but wood, but it was only $700.

you can also take the picture of the headboard to an upholsterer and get them to custom make it for you

Ask for one making, you can try companies like http://www.distinctivechesterfields.co.uk who provide bespoke furniture manufacturing and as they sell wing chairs...

I recently found a great place that builds custom upholstered headboards (AMP Upholstery). They also build wing back headboards, and from looking at there portfolio of work (http://www.amp-upholstery.ca), am sure they can build you your perfect custom headboard.

I think there prices are very reasonable, and the quality of work is better than any store bought product.
