Are there any king or queens size sheets made zippers, my mom take the sheets off her bed and walks around with them?

Thanks, I've tried various sites but am always directed to bed bug encasements which I donot need. I've done the nurses-corner to the sheets but I've found her tugging the ends of the sheets a loose. I was trying to avoid sewing two sheets and add a zipper however it looks like I may have to. Thanks golfbhard

I would google it. That way you won't have to run all over.
