Available in 4 different sizes, the Attends Night Preserver is a super absorbent underpad meant to protect your mattress from nighttime incontinence. The Night Preserver's facing is made of soft, non-woven material that, due to added fluff and polymers, quickly absorbs moisture while promoting skin health. This Attends underpad also features a new, diamond embossed pattern that allows it to better channel fluid and wick it to the underpad's core, providing you with drier, more comfortable sleep. The Night Preserver from Attends also features a peach, leak-proof backsheet that will not slip or slide during the night. With the non-slip backsheet, you know you’ll be protected all night long, even if you tend to toss and turn while sleeping.
