Antique Fainting Couch/Chaise Lounge

Google
Victorian Eastlake Antique Fainting Couch or Chaise Lounge and you’ll find ones that look quite a bit like yours and you can see what they are selling for and find more info. I’m not certain those are the same type as yours but think so.

It's Victorian Eastlake in style, most of the walnut variety predate the mid 1880's. The market peaked for them in the early 1990's, demand since then has declined a great deal, they go at auction for about what was paid or even less.
