Examples of real time couches?

Where can i find examples of couches done for real time projects? I need to make one, but i don’t know how to unwrap it or what technics to use (like trim sheet or something like that) to make textures look good, not too low res, so fabric, stitches and folds were looking good with 4k textures.

Why don’t you look for a free asset or check out places like chocofur, turbosquid or cgtrader. Maybe buy one too and help the artist out and learn how they did it. Then modify your own.
