If it was from Kohl's it was likely Levi's, Croft & Barrow or Docker's.

I have a Docker's one like this, and it's not BIFL - probably only 4 years old, the "leather" is already starting to peel on the outside.

I bought Quince sheets around a year ago after the set I inherited from my parents (probably from the 80s, judging on the pattern) started getting holes. They're pretty solid so far, and we just bought a set of Brooklyn Loom sheets to alternate on laundry day, but I haven't even slept on them yet so I can't speak to their quality.

I would NOT recommend Brooklinen though. Very thin, feel cheap, and get holes quickly (around a year and a half in, in my sister's case)

But yeah. I don't know if these quince sheets will last another 40 some odd years like my old set, but they seem pretty good so far.

Linen. Gets softer as it's washed.
