Understanding Underpads and Bed Pads: Reusable vs. Disposable

Underpads and bed pads are one of the most practical tools for protecting mattresses, furniture, and bedding from moisture, whether the need is related to incontinence, recovery from surgery, or simply added peace of mind. The main decision most shoppers face is reusable versus disposable, and the right answer depends on the situation, the amount of daily laundering that's realistic, and how the pads will be used.

What Underpads Are For

An underpad is an absorbent layer placed on top of a mattress, chair, or wheelchair seat to catch moisture before it reaches the surface underneath. They are used for a wide range of situations, from managing incontinence to protecting furniture during recovery from illness or surgery, to simple everyday reassurance. Most underpads combine a soft top layer with a waterproof backing, so moisture is absorbed and held rather than passing through to the mattress or chair beneath. Incontinence itself is common and often manageable — the National Institute on Aging notes that urinary incontinence becomes more common with age but is not an inevitable or untreatable part of aging, and encourages people experiencing new or worsening symptoms to talk with a healthcare provider about the underlying cause rather than only managing it with products. Explore the full category in our underpads and bed pads section.

Disposable Underpads

Disposable underpads are designed for single use and then thrown away, which makes them convenient for situations where washing and drying are not practical, such as travel, overnight care, or higher-frequency changes. They typically come in various absorbency levels, so heavier output can be matched with a higher-capacity pad. Many caregivers keep disposables on hand specifically for higher-need days or travel, even if washable pads are the everyday default. Browse our disposable underpads to compare sizes and absorbency.

Washable Underpads

Reusable, washable underpads are made from layered fabric that can go through the laundry many times before needing replacement. While the upfront cost per pad is usually higher than a disposable, the ability to reuse them can make sense for ongoing, longer-term use, and many people prefer the softer, cloth-like feel against the skin. Washable pads generally need to be laundered according to the manufacturer's instructions — typically without fabric softener, which can coat the absorbent layer and reduce how well it wicks moisture. See our washable underpads for options in different sizes and absorbency levels.

How to Choose Between Them

• Frequency of use — for occasional or short-term use, disposables may be simpler; for daily, ongoing use, washable pads can be more practical and cost-effective over time.
• Laundry access — washable pads require regular laundering, so consider whether that fits your routine or caregiving setup, including whether a washer and dryer are readily available.
• Travel and convenience — disposables are generally easier to pack and use away from home, or in settings where laundry isn't an option.
• Absorbency needs — match the pad's rated absorbency to the level of protection actually needed, since both disposable and washable pads come in light, moderate, and heavy-absorbency options.
• Skin sensitivity — some people find a cloth-like washable surface more comfortable against the skin over long stretches than a disposable pad's surface, particularly overnight.

Sizing and Placement Tips

Underpads come in a range of sizes, and choosing one that's too small for the mattress or chair leaves gaps at the edges where moisture can reach the surface underneath. For a bed, look for a pad sized to extend well beyond where the body typically lies, and consider a pad with "wings" or extra width that can be tucked under the mattress edges to help keep it in place overnight. For a wheelchair or recliner, a smaller, contoured pad designed for seating tends to stay in position better than a flat bed-style pad repurposed for a chair.

A Note for Caregivers

Keeping a bed protected overnight is one of the more frequent, practical concerns caregivers manage, and a mismatched or poorly placed pad is a common source of frustration — shifting during the night, not covering enough surface area, or not matching the level of absorbency actually needed. The National Association for Continence's caregiver guide to keeping the bed dry covers additional practical tips for combining underpads with other bedding protection strategies, and can be a useful reference alongside advice from a home health provider.

Protecting the Mattress Itself

In addition to underpads placed on top of the bed, a dedicated mattress protector adds a waterproof barrier directly over the mattress for extra peace of mind, especially useful for hospital beds or mattresses that are difficult to clean. See our mattress protectors to add an extra layer of long-term protection.
