It always wants to ride up the sides of my bed because elastic never wants to hold it in place. When I wash and dry my sheets it inevitably spirals up in the washer and dryer so it never washes or dries properly. Then it’s a pain in the ass to try and fold neatly.
I feel like I’m failing adulthood after being bested by a bedsheet.
Glue it to your bed. To wash, hose it down every few months. It takes about a week to dry the mattress, so you just have to get used to sleeping on a damp surface. Apply Febreze liberally.
