Jeckyll & Co has dated this piece to the Regency era.
1835, now held in the National Museum of Scotland. However generally the hollow section is at the top rather than the bottom of the leg.

Unusual too are the castors, stamped J.W LEWTY PATENT below a crown. I haven't seen this maker before, and on a fairly cursory online search found only three other examples.
One, usefully was closely related to chair made of mahogany rather than giltwood with a provenance of The Earls of Crawford & Balcarres, Balcarres House, Fife, sold by Lyon & Turnbull, lot 534, 3rd September 2020, Edinburgh.
Seat height 37cm.
