If you are caring for someone with bladder or bowel leakage, you have probably searched for "blue pads." That is what many people call disposable underpads: flat, absorbent pads with a leakproof backing that sit under a person to protect the bed or chair. This guide covers what to look for and how to use them. For a broader overview, see our blue pads explained guide.
What blue pads do for incontinence
Blue pads do not replace briefs or other products worn on the body. They protect the surface underneath: the mattress, the recliner, the wheelchair seat or the sofa. The soft top layer takes in moisture, and the waterproof backing helps keep it from reaching the surface below. Many caregivers use a pad together with an adult brief for extra protection overnight.
What to look for
- A real leakproof backing. The backing is what protects the mattress. Look for a clearly stated waterproof film layer. Ours uses a 22 gsm polyethylene film.
- A quick-dry top sheet. A non-woven top sheet feels drier against skin than a plain paper surface.
- An absorbent core. Our pads use a sodium polyacrylate super absorbent polymer with fluff pulp, in eight layers in total.
- Enough size. A 30 x 36 inch pad covers most of the middle of a twin or full bed, or a chair seat. See our size guide if you are unsure.
- Cost per pad. If you change pads daily, a bulk pack matters. Our 50-count pack of 30x36 blue disposable underpads is $64.99, about $1.30 per pad.
How to use a pad on a bed
- Put a fitted sheet on the mattress first.
- Lay the pad flat with the soft side up and the blue backing down, centered under the hips.
- Smooth out wrinkles so moisture does not run to the edges.
- Change the pad as soon as it is wet or soiled, and wipe the area clean before putting on a fresh one.
How many to keep on hand
It depends on how often the person needs a change. Someone who needs one change a day uses about 30 pads a month, so a 50-count pack lasts a little over a month. For nightly use plus daytime chair protection, plan on two to three a day.
Good to know
Disposable underpads are not a medical device and are single-use, so do not wash and reuse them. If skin looks irritated or leaks keep happening, talk to a doctor or nurse about the right care plan.
