OP, I mentioned the following below in a reply to someone mentioning good toe nail clippers, because I’ve personally had a related problem below ⬇️

📍I’ve got to add to this by saying that I’ve got restless leg (and feet) syndrome, which has caused my sheets excessive wear and tare the last several years. Nails being nicely trimmed, it’s still very likely to happen. When I finally realized that’s what caused my sheet problem it was such an “AHA moment” for me!

Also, OP, someone mentioned using flat sheets vs fitted in the comments. I’ve not done any research myself, but I have a friend who’s been self employed in the cleaning business over 30 years now, who’s told me hotels etc, use flat sheets only (as does she), because the ware and tare is so much less than using fitted sheets.

When thinking about what she’d told me years ago, i can only recall having noticed that housekeeping uses flat sheets only when making beds, typically using two flat sheets on the mattress itself in such a way that they stay put, and last longer
