This is a video showing how to set up a reproduction of Washington's field bed.     The key word here is "likely" nothing ties this bed to G. Washington,    "George Washington’s Military Trunk Bed Used During the Revolutionary War, 1775  February 29, 2024     1700s, celebrity & famous people, event & history, military, war    George Washington carried folding beds, tents, eating utensils, and other equipment to use while encamped on the field with his troops during the Revolutionary War. Washington likely used this bed when he traveled from his Newburgh, New York, headquarters in July 1783 –– as the war was winding down –– to tour upstate New York and the military installations located there.   Unlike the fancy field bedstead, this bed is more similar to a modern camping cot. Made with metal legs, the lid of the trunk was used as a headboard. This bed was highly transportable, all fitting into a trunk after use."

I went there last year. Right next to it is a redwood grove. Pretty cool. 

This is Washington's field bed at Mt. Vernon. Take the time to look at the construction in the detail photo's. I saw the link you got that pic from.   In October 1775, shortly after assuming command of the Continental Army, George Washington acquired "a Field Bedstead & Curtains, Mattresses, Blankets etc. etc." Designed for portability and durability, this bedstead's tapering posts, turned legs, and rails are ingeniously hinged so it can be folded into a compact bundle for easy transport. https://www.mountvernon.org/education/primary-source-collections/primary-source-collections/article/field-bedstead

I would guess the Army Corps of Engineers in this case is not the Army branch but rather the civilian origination that is in charge of inland waterways and flood control. I found this on the internet; Carbon Canyon Dam, located near Brea, California, is owned and operated by the U.S. Army Corps of Engineers, Los Angeles District (LAD). It's primarily for flood control in the Carbon Canyon Creek drainage basin and is part of a system that includes Brea and Fullerton Dams to protect the coastal plains of Orange County. Construction of the dam was completed in 1961.   

Looks like a good one to me.  Does it have a "silky" feel to the front?  The ones that I have are very distinctive in their feel and almost a floppy, silky feel to them.  Based on the pictures, I would say you have a good one here.

Of all the things I have never seen before I gotta say this is cool. My gut feeling based on almost nothing is that this is post Revolutionary war. The metal work on the bed frame hints at something later on in the industrial revolution. Just my two clad cents.  

Welcome to the forum. My maternal Grandfather grew up on the Isle of Wight.

I hope he’s still around, great guy.
