Rare Antique Vintage Folding Adjustable Oak Back Rest Bed  Pillow  Support

Nice iron ratchet device for holding at various angles. The nail holes around the top and sides indicate that this once had fabric stretched across it. I have seen something newer along the same lines that had webbing. Also you can find new metal pipe frames

Probably early 1900s.

Other possible uses: A giant book stand, easel support

23 1/2"  wide x 28 1/2" high.
