I’ve moved into a new place and have been in this bed for two months now. I bought brand new sheets and within a month, they were torn up. I put this older one on and the same thing a month later. I wear socks to bed every night so I doubt it would be my toenails ripping the sheets (the big rip is where my feet would be and the smaller holes are where my bum/hips would be, this is where the big tear was on the last sheet.) I seriously cannot understand why this is happening, I don’t move around in my sleep and I don’t wear any jewellery when I sleep nor do I have long or sharp fingernails. Does anyone know how this could possibly be happening?
