Attends makes more underpads than almost anyone else, and that is exactly the problem when you are shopping. Dri-Sorb, Dri-Sorb Advanced, Discreet, Night Preserver, and Supersorb all show up in search results, they all look like white or blue rectangles in the product photos, and the names do not tell you which one actually holds up overnight.

This guide sorts the Attends underpad range by what it is built to do. You will find every line explained, a full size chart from 17 x 24 inches up to 36 x 51 inches, and a straight answer on which pad to buy for daytime chair protection, overnight bed protection, or someone at risk of skin breakdown.

The five Attends underpad lines

Line	Absorbency	Built for	Back sheet
Dri-Sorb	Light	Chairs, car seats, changing surfaces, general spills	Poly
Dri-Sorb Advanced	Moderate	Daytime bed and furniture protection	Poly
Discreet	Light to moderate	Everyday use where a lower profile pad is preferred	Poly
Night Preserver	Heavy	Overnight bed protection	Poly
Supersorb	Heavy to severe	Overnight, repositioning, skin health	Breathable, air permeable

The single most useful thing to know: only the Supersorb line has a breathable back sheet. Everything else uses a standard poly backing. If you are searching for attends supersorb breathable underpads, that breathability is the reason the line costs more, and it is not a marketing detail. Air permeable backing lets the pad be used on low airflow and alternating pressure mattresses, which a poly backed pad blocks.

Attends Dri-Sorb underpads: the everyday workhorse

Dri-Sorb is the economy line and the one most people mean when they search for attends disposable underpads or attends bed pads without a line name attached. Light absorbency, fluff core, poly backing. These are the pads you keep a stack of for chairs, car seats, exam surfaces, and changing.

• Dri-Sorb 17 x 24 inches, #UFS170, sold in 3 packs of 10 or a case of 300
• Dri-Sorb 23 x 24 inches, #UFS230, pack of 10 or case of 200
• Dri-Sorb 23 x 36 inches, #UFS-236, pack of 10 or case of 150
• Dri-Sorb 30 x 30 inches, #UFS-300, pack of 10 or case of 150

Do not put a Dri-Sorb on a bed overnight and expect it to hold. It is not built for that volume. Use it where a small amount of fluid needs catching and cost per pad matters.

Attends Dri-Sorb Advanced: a step up in core

Same family, moderate absorbency instead of light, with a stronger core. This is the right choice for daytime bed protection or for someone with moderate leakage who changes the pad more than once a day.

• Dri-Sorb Advanced 23 x 36 inches, #UFP236, pack of 10 or case of 150
• Dri-Sorb Advanced 30 x 30 inches, #UFP300, pack of 10 or case of 150
• Dri-Sorb Advanced 30 x 36 inches, #UFP-360, pack of 10 or case of 100

There is also Attends Discreet, #UFS236RG at 23 x 36 inches, which comes 15 to a pack instead of 10 and works well as a general purpose everyday pad.

Attends Night Preserver underpads: heavy overnight absorbency

Night Preserver is the answer when the pad has to last through a full night without a change. Heavy absorbency, and the line runs in the largest bed sizes Attends offers outside the Supersorb range.

• Night Preserver 30 x 30 inches, #UFPP300, pack of 10 or case of 100
• Night Preserver 23 x 36 inches, #UFPP236, pack of 10 or case of 150
• Night Preserver 30 x 36 inches, #UFPP-360, pack of 10 or case of 100
• Night Preserver 36 x 36 inches, #UFPP366, pack of 10 or case of 50

For most households dealing with nighttime incontinence, Night Preserver at 30 x 36 inches is the practical default. It covers the sleeping area, it holds a full night, and it costs less per pad than Supersorb.

Attends Supersorb underpads: breathable, repositionable, premium

Supersorb is the top of the Attends underpad range and the line most often specified in facilities. Three things separate it from everything above.

• Dry-Lock core. Super absorbent polymer channels pull fluid away from the surface instead of holding it against skin, which is different from a fluff core that simply soaks.
• Breathable back sheet. Air permeable backing means it can be used on low airflow and airflow therapy mattresses, and it reduces heat and moisture buildup underneath the person.
• Repositioning strength. The reinforced back sheet is rated to help reposition patients up to 400 pounds without the pad tearing or bunching, which matters enormously for caregivers moving someone in bed alone.

Here is what we stock, in order of strength:

• Supersorb Advanced 23 x 36 inches, #ASB2336, pack of 5 or case of 70
• Supersorb Advanced 30 x 36 inches, #ASB300, pack of 5 or case of 60
• Supersorb Advanced Ultra-Max 30 x 36 inches, #ASB3036, pack of 5 or case of 60
• Supersorb Maximum 30 x 36 inches, #ASBM3036, pack of 5 or case of 60
• Supersorb XL Bariatric 36 x 51 inches, #ASBXL, pack of 5 or case of 30

The Bariatric XL at 36 x 51 inches is the largest disposable underpad we carry. It is designed for individuals whose weight places extra pressure on the bladder and who need coverage well beyond a standard bed pad.

A note on Attends Premier underpads

Attends lists Premier as its most absorbent overnight underpad. We do not currently stock the Premier line. If that is what brought you here, the two closest products we carry are Night Preserver 30 x 36 inches for straightforward overnight absorbency, and Supersorb Maximum 30 x 36 inches if you also need the breathable back sheet and repositioning strength. Call us and we can tell you what we are able to order in.

Attends underpad size chart

Every Attends underpad size we carry, and what each one is practically for.

23 x 36 inches	Dri-Sorb, Dri-Sorb Advanced, Discreet, Night Preserver, Supersorb Advanced	Narrow bed coverage, twin beds

36 x 36 inches	Night Preserver	Wider coverage for restless sleepers
36 x 51 inches	Supersorb XL Bariatric	Bariatric care, full width beds

If you are shopping specifically for attends underpads 30 x 36, that size has the most options by a wide margin. Six of our Attends SKUs land there, spanning moderate absorbency up to Supersorb Maximum, so you can move up or down in absorbency without changing the footprint on the bed.

How to choose the right underpad

1. Start with when it will be used. Daytime with regular changes means Dri-Sorb or Dri-Sorb Advanced. A full night without a change means Night Preserver or Supersorb.
2. Check the mattress. If there is a low airflow or alternating pressure mattress involved, you need a breathable back sheet. That means Supersorb. A poly backed pad defeats the mattress.
3. Consider skin. If the person spends most of the day in bed or is already showing redness, moisture management matters more than raw absorbency. The AHRQ has a good overview of pressure ulcer prevention in long term care, and moisture control is a consistent theme in it. Talk to a nurse or wound care clinician about the full picture rather than relying on a pad alone.
4. Match the size to the bed, not to the person. A pad that is too narrow gets pushed aside during the night and the fluid ends up on the sheet anyway.
5. Buy by the case once you know what works. Cost per pad drops sharply. Buy a pack first to confirm the fit, then move to cases.

Frequently asked questions

What is the difference between Attends Dri-Sorb and Supersorb?

Dri-Sorb is a light absorbency fluff pad with poly backing built for everyday surface protection. Supersorb uses a Dry-Lock polymer core and a breathable back sheet, holds far more, and is strong enough to reposition someone in bed.

Are Attends Supersorb underpads breathable?

Yes. The Supersorb line uses an air permeable back sheet, which is why it can be used on airflow therapy and low air loss mattresses. No other Attends underpad line is breathable.

What is the best Attends bed pad for overnight?

Night Preserver 30 x 36 inches for most home situations. Step up to Supersorb Maximum 30 x 36 inches if breathability, repositioning strength, or skin protection is a factor.

Do you carry Attends Premier underpads?

Not at this time. Night Preserver and Supersorb Maximum are the closest products we stock.

What size Attends underpad fits a standard bed?

30 x 36 inches is the most common choice and the size with the widest selection. Move to 36 x 36 inches if the person shifts position a lot overnight.

What is the difference between Supersorb Advanced, Ultra-Max, and Maximum?

All three share the Dry-Lock core and breathable backing at 30 x 36 inches. Advanced is the baseline, Ultra-Max adds absorbency, and Maximum is the strongest of the three and the one usually chosen for severe incontinence.
