I am pretty sure there is one upholsterer who can do this where you live. I live in Myanmar.

Hi Alicia, the very first piece of 1 inch foam you see us gluing on the seat is called rebonded foam. It is basically compressed foam offcuts of different colors. It is really tough and will never give. It will still provide a certain degree of comfort even when the top layer of foam is completely flat from usage. The second pink one is a high density half inch foam it is glueable and will bend around the corners and follow the contours of the seat. This provides a softer touch you won't get from the rebonded foam alone. Make sure you glue every layer because it is a curved seat and you don't want any air pockets in between. You can use any commercially available upholstery glue ( spray on or spreadable ) for the purpose. Also avoid very thick leathers and make sure to tuck the corners in neatly. Drive the decorative nails in afterwards and you are good to go. Hope this helps !

@@DesignsbyLinTin Thank you so much for the detailed information!

I made the strip myself. It's just a little strip of leather with edges tucked in and glued. The best glue for these kinds of things is contact adhesive. I'm sure you can use the spray-type as well. I used the thick spreadable version of it. Faux leather is fine, just make sure it is not too thick otherwise, it won't go around the corners nicely.
