Sarah check out Ikea Poang in leather - brown, black or off white. It's a similar look at a much more wallet friendly price point and they have matching ottomans as well. https://www.ikea.com/us/en/catalog/products/S89829138/

I was looking for some housing ideas and I was going through some random videos on youtube. I came across this video https://www.youtube.com/watch?v=dqA0O4n_fCo At 2 minute 30 seconds, the video shows a chair. I found it really interesting. Can anyone suggest where to shop for those chairs ?

Don’t know your budget. Most companies make them. Check Rowe. (Unless you are actually looking for barrels that were turned into swivel chairs?! They were a thing back in the 1950s!)

Info at bottom about the room, maybe try contacting any involved. Good luck. :) https://www.ramdesign.com/southampton-project
