Tom Scott Antiques has dated this piece to the Edwardian era.
Both in good condition and a fabulous colour tone.

They can be used on a standard 3' single bed, but you could obviously used them on a 6' superking bed too.
There are two wooded struts fitted the the back of the headboards which are for locating to the divan bases. These look to be in a "standard" position, so should fit any divans, but you might need to adjust them if required.

They are a 3' or 91.5cm width, so they will fit a standard size bed perfectly and the horizontal gilded line you can see at the base is usually where the pillow level would be, but you can raise or lower them to suit you.
Priced as the pair and measuring:
38 1/4’’ or 97cm panel height ( not including the struts )
36’’ or 91.5cm wide
