They look antique and refinished to match walls. These could easily be replicated by having the pattern traced & cutout by carpenter (some hardware or lumber yards will do this for you or find a carpenter). Have a painter paint it for you. It can then be easily attached to any bed frame. Or, look in antique, consignment, garage and estate sales in the paper or on line (or new furniture stores) and have it painted to you're specifications.
I hope this helps you.

The beds and also the chair were both designed by Ann Graham! For more of her designs go to www.Porteitalia.com. The collection is fantastic and custom orders are always available. Each piece is handmade in Italy and the finishes are wonderful. Here is an example of another bed:

HI Margaret, for the bedskirt - I like the fullness of it and would like my seamstress to make my daughters with this volume. What should I ask for - 2.5" fullness or more?? Thanks
