What Is Inside a Weighted Blanket: Discovering Comfort and Science

Weighted blankets have gained popularity for their therapeutic benefits, often recommended for their ability to improve sleep and reduce anxiety. But what exactly is inside a weighted blanket that makes it so effective?

Let’s unwrap the layers of a weighted blanket to understand its contents and the science behind its comforting weight.

What Is Inside of a Weighted Blanket?

Weighted blankets are engineered to provide comfort and therapeutic benefits through what is often termed as deep touch pressure. The fillings inside these blankets are pivotal in delivering this sensation, mimicking a firm, gentle hug. Here are the common types of fillings used and how they contribute to the blanket’s effectiveness:

  1. Plastic Poly Pellets:

    • Composition: These are typically made from polypropylene, a type of plastic that’s both durable and non-toxic.
    • Characteristics: They are round, smooth, and about the size of a pea, making them perfect for even weight distribution without discomfort.
    • Benefits: Poly pellets are hypoallergenic and do not absorb moisture, which helps in maintaining the blanket’s hygiene and longevity.
  2. Micro Glass Beads:

    • Composition: These tiny beads are finer than sand and are made from glass.
    • Characteristics: Due to their small size, glass beads make the blanket feel less bulky and allow for a more contoured fit to the body.
    • Benefits: They are denser than plastic pellets, which means a heavier blanket does not necessarily have to be as thick, enhancing the comfort for the user.
  3. Steel Shot Beads:

    • Composition: These beads are made from steel and are larger and heavier than both plastic pellets and glass beads.
    • Characteristics: Their size and weight can make the blanket feel significantly heavier with less material.
    • Benefits: They are extremely durable, although their weight can make the blanket less flexible and potentially noisier when moved.
  4. Natural Grains:

    • Composition: Common grains used include rice, barley, and millet.
    • Characteristics: These are all-natural fillers that are biodegradable and eco-friendly.
    • Benefits: They are perfect for those who prefer all-natural products; however, they can degrade over time and may develop odors if they absorb moisture.

Each of these materials has its own set of benefits and potential drawbacks, and the choice of material can affect the overall experience of using the weighted blanket.

What Makes a Weighted Blanket Heavy?

The fundamental purpose of a weighted blanket is to provide a firm, gentle pressure across your body, and the factors influencing this weight are crucial for their efficacy:

  1. Type of Filling Material:

    • The material chosen as the filling affects not only the weight but also the comfort and usability of the blanket. For instance, glass beads are denser and heavier, allowing for a heavier blanket without the bulkiness associated with lighter materials like plastic pellets.
  2. Amount of Filling:

    • The weight of the blanket is directly proportional to the amount of filling used. More material equals more weight, but this must be carefully measured to maintain comfort and effectiveness.
    • Distribution Technique: The way in which the filling is distributed within the blanket impacts its functionality. Ideally, the weight should be evenly distributed to ensure that the pressure is uniformly applied across the body. This is often achieved through well-sewn pockets throughout the blanket that keep the filling material in place.
  3. Blanket Size:

    • The size of the blanket also plays a role in how heavy it feels. A larger blanket spread out over a king-size bed, for example, will need more filling to achieve the same weight per square inch as a smaller throw blanket.
  4. User’s Body Weight:

    • The ideal blanket weight is typically around 10% of the user’s body weight. This guideline helps ensure that the blanket provides effective deep touch pressure without being too heavy to comfortably move under.

A properly chosen weighted blanket can perfectly complement a Puffy Lux Mattress, enhancing the overall sleep experience by combining deep touch pressure with optimal body support.

How to Choose the Right Weighted Blanket

Choosing the right weighted blanket involves more than picking a color or pattern that suits your bedroom—it’s about finding the right combination of weight, size, and material to suit your personal needs. Here’s how to make sure you select the most suitable weighted blanket for you:

  1. Determine the Right Weight:

    • General Guideline: A good starting point is to choose a blanket that’s approximately 10% of your body weight. This proportion is recommended to provide effective deep touch pressure without being overly restrictive.
    • Personal Preference: Depending on your personal comfort and sleep habits, you might choose a blanket that’s slightly lighter or heavier. Some people may prefer a lighter touch, while others may benefit from a bit more weight.
  2. Select the Appropriate Size:

    • Fit Your Bed: Make sure the blanket fits your bed size but doesn’t hang over the edges, as this can pull the blanket off during the night.
    • Personal Use: If you plan to use the blanket primarily for personal relaxation or while sitting, a smaller size that wraps around your body may be ideal.
  3. Choose the Filling Material:

    • Consider Texture and Noise: Decide between smoother glass beads, silent but potentially bulkier plastic pellets, or the natural feel of grains. Each has a different feel and sound when moved.
    • Allergy Considerations: If allergies are a concern, opt for hypoallergenic materials like glass beads.
  4. Fabric Type:

    • Comfort and Care: Consider the outer fabric of the blanket. Options like cotton are breathable and easy to clean, while minky or fleece provide warmth and a soft touch.
  5. Ease of Cleaning:

    • Washable Options: Look for blankets that are machine washable or come with a removable cover to ensure easy maintenance.

By integrating the soothing weight of a weighted blanket with the luxurious comfort of a Puffy Lux Mattress, you create an ideal sleeping environment that nurtures both mind and body.

From my own use, the transition to a weighted blanket was transformative, enhancing not just sleep quality but also reducing nighttime anxiety. Paired with the cloud-like comfort of the mattress, the combination provides a cocooning effect that helps my family and me to fall asleep faster and stay asleep longer.


Understanding what is inside a weighted blanket reveals the thought and engineering that goes into creating these therapeutic covers. Whether you’re seeking better sleep or need a comforting touch during stressful times, a weighted blanket can be a valuable addition to your bedtime routine.
