A Guide to Underpads

If you or your loved one manages heavy incontinence, you know that sometimes leaks soak through incontinence products. When this happens, a second line of defense is needed to protect against stains and spills, and underpads, also called chux, are an excellent option.

In this guide, we’ll explain how to choose the underpad to successfully manage leakage and show you how to easily get your products free* through Medicaid.

What Are Underpads (Chux)?

Underpads, also called chux pads or bed pads, are heavy-duty absorbent products that help protect furniture, mattresses, wheelchairs, and other surfaces against daytime or overnight incontinence (bedwetting). These disposable underpads are quilted with high-absorbency materials that soak up leaks and odors.

Types of Underpads (Chux)

There are two types of chux that may be helpful for those with heavy incontinence.

Reusable Underpads

Reusable underpads are washable pads that can be used multiple times. These pads have absorbent cores and are made with cotton or polyester materials for comfort. Because they can be washed and reused many times, reusable underpads are more environmentally friendly than disposable bed pads.

Disposable Underpads

Disposable underpads are single-use pads that may be more sanitary than reusable underpads. Disposable pads offer users easy changes and clean-ups because they can be thrown away after being soiled. The top sheet of disposable chux also provides skin comfort and breathability while soaking up leaks. 

Underpads (Chux) Features

Consider the following when choosing your booster pad.

  • Absorbency


    Disposable underpads come in a variety of absorbency levels that suit different incontinence needs. When choosing your underpad, consider which level of absorbency you need.

    • Moderate Absorbency: Best for moderate leaks.
    • Heavy Absorbency: Best for those with heavy leaks.
    • Overnight Absorbency: Best for those who need overnight absorbency.
  • Size


    Sizes for chux vary, with the most common sizes being 23“x36” to 30”x30."

    Consider which type of materials you’re trying to protect from leakage and how large the area is and choose a size that will cover the area. Selecting the wrong size of chux could result in stains or spillage.

  • Waterproof Backing

    Waterproof Backing

    Absorbent underpads are made with waterproof backing that protects surfaces like car seats, chairs, bedding, mattresses, and other household furniture. The backing prevents leaks while keeping the user dry.

  • Material


    Breathable underpads are made with a soft, cotton-like material that keeps skin healthy and protects it by allowing airflow to the skin. Most chux are also hypoallergenic, bringing ultra comfort to users.
