Whats in a Weighted Blanket?

Curious about whats in a weighted blanket that makes it so comforting? Let's explore the various types of fillers that add weight to these blankets.

With options containing glass beads, sand, and steel beads, and even those without any fillers (our favorites), we'll take this bedding apart.

We will also look into the materials that make up the blankets themselves. Additionally, we'll discuss materials to avoid, how weighted blankets are made, the best materials for these blankets, and how they work to improve your sleep.

Let's learn more about what makes weighted blankets so special.

What this article covers:

What Type of Fillers Go in Weighted Blankets?

What are weighted blankets made of? The secret behind the soothing effect of weighted blankets lies in the weight. This is typically achieved using various fillers. These vary widely, from glass beads to sand, steel beads, pebbles, and even options without any fillers.

Here are the details.

Glass Beads

Glass beads provide a uniform weight distribution, making the blanket feel evenly heavy across its surface. The main advantage of glass beads is their density.

However, glass beads can sometimes shift within their compartments, causing slight noise and requiring the blanket to be sectioned off meticulously to prevent uneven weight distribution. Additionally, they are typically more expensive than other fillers.


Sand is another filler used in weighted blankets. This filler has significant downsides. It can retain moisture, leading to potential mold or mildew issues if the blanket gets wet.

Sand also tends to clump over time, which can result in uneven weight distribution and a less comfortable experience. Moreover, sand-filled blankets are generally harder to clean, as the filler cannot be exposed to water without risking damage.

Steel Beads

Steel beads are much heavier than glass beads, meaning fewer are needed to achieve the same weight.


That said, their potential noise (for those with auditory sensitivities) is a factor to consider when deciding which type of weighted blanket to purchase.


Pebbles, though less common, offer a natural and eco-friendly filler option for weighted blankets. Their irregular shape and varying sizes can provide a unique sensory experience, with a more organic weight distribution.

The irregularity of pebbles can also be a drawback, as it may lead to uncomfortable pressure points. Pebbles do not always distribute weight evenly, which can affect the blanket's effectiveness in providing even pressure.

Additionally, pebbles can make the blanket bulkier and more challenging to wash, limiting its practicality for regular use.

No Filler

The no-filler option represents a revolutionary approach in the world of weighted blankets, eliminating the need for traditional fillers. Instead, these blankets achieve their weight through their weave and material makeup.

Based on our observations, this innovative method offers an even distribution of weight without the risk of filler leakage, shifting, or noise.

No-filler weighted blankets are easier to maintain, as they can often be washed more conveniently than their filled counterparts. They also tend to be more durable, without the risk of filler degradation over time.

What Are Weighted Blankets Made of?

Weighted blankets are not just about the fillers; the materials that make up the rest of the blanket play a central role in the overall user experience. How so, you ask? Let's discuss.

Weighted Blanket Fabrics

The fabrics used in weighted blankets are chosen for their durability, comfort, and breathability. Common materials include cotton and bamboo.

Each fabric offers distinct advantages, from the cool, breathable nature of cotton to the moisture-wicking properties of bamboo.

Cotton is widely favored for its natural breathability and softness, making it an ideal choice for those who prefer a cooler sleeping environment. It's also durable and easy to care for, suitable for regular washing.

Our cotton knitted weighted blanket is a sustainable masterpiece, perfect for every season. It bears certifications from leading independent authorities OEKOTex and GOTS, ensuring it meets the highest standards of environmental and social responsibility.

Chunky-Knitted Weighted Weaves

Our research indicates that chunky-knitted weighted blankets are a modern take on traditional weighted blankets, eliminating the need for fillers by using thick, heavy yarns to create the weight.

These blankets are knitted in a way that the very structure of the weave contributes to the overall heaviness, providing a unique, evenly distributed weight across the blanket.

This innovative approach not only adds a decorative element to the room but also offers a tactile experience that can be soothing and comforting. The open weave of the chunky knit allows for excellent airflow, making these blankets a suitable choice regardless of the weather.

The chunky-knitted weave also provides a distinctive, stylish look that sets it apart from traditional weighted blankets, blending functionality with home decor.

Materials to Avoid When Buying Weighted Blankets

In the quest for the perfect weighted blanket, it's important to steer clear of materials that are non-breathable or potentially allergenic, as they detract from the comfort of a weighted blanket. Synthetic materials can cause overheating, ruining the joy the blanket is supposed to provide.

Heavy metals or materials that can lead to an uneven distribution of weight should also be avoided, as they can make the blanket feel lumpy and uncomfortable.

Additionally, materials that are prone to breaking down or leaking out of the blanket can create messes and reduce the blanket's lifespan. Opt for high-quality, natural materials that help you avoid these issues.

How Are Weighted Blankets Made?

The construction starts with choosing the fabric and filler that will provide the desired weight and texture. Then, the steps vary depending on the type of filler.

Filler-free blankets are crafted using a unique approach that eliminates the need for traditional weighted fillers like glass beads or plastic pellets. The process involves knitting with a chunky, dense yarn.

The technique used is a tight, chunky knit pattern that increases the blanket's weight without compromising its softness or flexibility.

What Material is Best for Weighted Blankets?

Our findings show that cotton stands out as the best material for weighted blankets due to its breathability, strength, and comfort. This natural fiber is gentle on the skin, making it suitable for people with sensitive skin or allergies.

Cotton's ability to regulate temperature makes it an excellent choice for a comfortable sleep experience, keeping the user cool in summer and warm in winter.

Cotton is also highly durable, able to withstand frequent washing without losing its softness or shape. This makes it an ideal choice for those considering, “which weighted blanket is best for me?”.

How Weighted Blankets Work

Regarding weighted blanket benefits, weighted blankets work by applying gentle, even pressure across the body, a principle known as Deep Pressure Stimulation (DPS).

This pressure mimics the sensation of being hugged, promoting relaxation and stimulating the release of serotonin and melatonin, neurotransmitters that help regulate sleep and mood.
