Query: It works!

We got my kids new beds and mattresses and for the last few months, my daughter had been unable to keep her damn sheets on her bed. Like we put them on and when she wakes up they're off completely. Totally infuriating! We hooked these bad boys up as soon as we got them and haven't had any issues since! I admit, it is a PIA because we have to flip the mattress to attach, but I'd we work together it isn't awful.
