Typical fitted sizes are about 17 inches wide by 32–33 inches long, and some covers list a depth of around 6 inches.
Care instructions vary, but most specify machine washing (often machine wash cold and tumble dry low). Some cotton options recommend washing before first use.
Many covers have a quilted top and use polyester/poly fill batting (or similar) to provide cushioning and support.
Fitted covers commonly use elastic edges or partial elastic gussets so they fit standard rectangular pads, and many designs also accommodate contoured pads.
Most listings note a suggested age of “Newborn and Up,” indicating they’re intended for newborns and older infants.
Muslin quilted covers typically use polyester/poly fill batting for cushioning while the top is 100% muslin cotton.
Finishes include elastic edges on fitted covers, quilted diamond stitching to hold the lining, and corded gussets or trim for a tailored edge.
