I used these when I was providing home care, but I no longer need them as I've moved into a facility. They were very useful. Set includes: * Yellow-green single size * Beige single size * Light blue small sheet * Blue check 4 sheets 80x120 A typical layering order I used was: ① Yellow-green single size on the bottom, ② regular sheet, ③ disposable vinyl care sheet, ④ blue check mini sheet on the bottom for the buttock area. I have 4 of the ④ sheets for changing. I used the light blue small sheet on the car seat. I wash them frequently, but they are not new, so there is a feeling of use, but I think it's good to have several of these. As a bonus, I'll include a bag of disposable vinyl sheets. - Purpose: Waterproof/Care Sheets Thank you for looking.
