Best Weighted Blanket Fillings: Popular Filling Materials and How to Choose

Weighted blankets, or gravity blankets, have become increasingly popular due to their therapeutic benefits. They are said to mimic Deep Touch Pressure Stimulation, which relaxes the nervous system, produces a calming effect, and lowers the heart rate. 

This simulation helps sleepers fall asleep faster and improve sleep quality. This is especially important for people with autism and those dealing with chronic pain, stress, and anxiety. Additionally, it eases the symptoms of anxiety disorder, attention deficit hyperactivity disorder (ADHD), and autism spectrum disorders.

Because of the many benefits of weighted blankets, it’s no wonder why more and more people are getting interested in trying them. If you are someone who wants to experience the benefits of weighted blankets for yourself, then one important thing you should know is that the pressure exerted depends largely on the filling materials stuffed inside the blankets. 

Depending on the material you choose to use in your gravity blanket, the outcome of the pressure you feel will vary accordingly, so it is imperative that you find what is suitable for you personally.

What Are Weighted Blanket Filling Materials?

Filling materials are weights used to fill weighted blankets. They are stitched inside square pockets and designed to conform to the curves of the body. Since they are heavy enough, they stimulate Deep Touch Pressure that offers a sense of comfort and security.

Knowing the different weighted blanket filling materials is important for optimal comfort and safety. In addition, the blanket will be in direct contact with the skin, so choosing safe, non-toxic materials is crucial.

To choose the right weighted blanket filler, let’s take a closer look at the most common filling materials, as well as their benefits and drawbacks:

Plastic Poly Pellets

Poly pellets, also known as weighted stuffing beads, are one of the most commonly used weighted blanket fillers. They are usually made of polypropylene plastic, which is considered to be a safe level 5 plastic. This material is great because it easily follows the curve of the body once sewn into the fabric.

Pros

Cons

Cost-effective 

Not eco-friendly

Non-toxic

Can sometimes give off an initial odour

Usually washable

Can sometimes clump, causing uneven weight distribution

Easily accessible

Its uneven texture may feel abrasive for extremely sensory-sensitive individuals

Long-lasting

 

Micro Glass Beads

Micro glass beads, considered the most luxurious filling material, are tiny glass fillers that look like white sand or salt crystals. They are cool to the touch, so they are usually used in cooling weighted blankets.

This filling material makes a great alternative to poly pellets because it is more eco-friendly. These beads also have a consistent shape and smooth edges. Because of this, they are ideal for those who tend to get bothered by the texture of poly pellets.

Pros

Cons

An environmentally friendly alternative to poly pellets

More expensive than poly pellets

Hypoallergenic

Cheaper glass beads may contain lead

Machine-washable

Sometimes shift to the sides, causing uneven weight distribution

Dry cleaner-safe

More likely to leak through the stitches of the blanket

Easily accessible

Durable

Odorless

Less clumpy

 

Nano-Ceramic Beads

Nano-ceramic beads are made using nano-particle technology, which involves mixing tiny ceramic particles within a solution and gel. 

This material is excellent for weighted blankets because it contains a high percentage of air, which means it’s lightweight. It is also durable, thanks to its outstanding strength and flexibility. Additionally, it blends better and creates a more balanced weight distribution than other filling materials.

Pros

Cons

Lightweight

Not as readily available as other weighted blanket fillings

Durable

May be more expensive

Extra small, which is perfect for those who are very sensitive to touch

 

Steel Shot Beads

This weighted blanket filling material promotes calm and comfort since it has a completely smooth, round surface. However, the beads are heavy, so they may be too noisy when they move about inside the blanket. 

Pros

Cons

Cost-effective

Can be noisier than glass beads and plastic pellets

Washing machine-safe

Can feel lumpy on the body

Extremely durable

Doesn’t leak through the stitches of the blanket easily

 

Crystals

Crystals are believed to hold vibrational frequencies that promote natural healing. When combined with Deep Touch Pressure, they potentially offer a more restorative sleep. For this reason, some are drawn to using them as filling materials for their homemade weighted blankets.

Pros

Cons

Ideal for people who believe in holistic healing

Expensive

Not as easy to wash as other filling materials

May feel lumpy, depending on the cut and finish of the crystals

 

Sand

Sand is a common weighted blanket filler that is cheap and easy to buy. Unfortunately, washing and drying a blanket stuffed with this material is challenging. 

Since it is extremely fine, this filling material can clump and cause the blanket to lose its shape after the first wash. The blanket filled with sand must also be air-dried, so drying takes longer.

Pros

Cons

Inexpensive

Tends to clump

Easily accessible

Washing and drying are difficult

Likely to leak through the stitching

 

Dried foods

Dried foods, such as beans, rice, barley, or corn, are sometimes turned into weighted blanket filling materials. They are not common in commercially available blankets, but they are often used by those who prefer homemade ones.

This material may be cheap, but it isn’t an ideal filling material. Food eventually disintegrates and rots, so using it for your blanket might eventually mean having smelly and infested bed linen.

Additionally, cleaning a weighted blanket filled with food is a nightmare. Since food is porous, it will retain water without completely drying out. As a result, the blanket becomes moldy after the first wash.

Pros

Cons

Inexpensive

Food might break down over time

Easily accessible

Not durable 

Can grow mold and fungus

May give off an odor 

May attract insects

 

Rocks

Riverstones, pebbles, and gravel are commonly used as homemade weighted blanket fillers. These are small, lightweight, and similar in size to ensure even weight distribution.

Before sewing them into the lining, these rocks are completely dried out to avoid mold growth. Padding is also added for comfort.

Pros

Cons

Cost-effective

May cut through the fabric due to sharp edges

Easily accessible

Tend to feel lumpy on the body

May feel too warm for hot sleepers

May feel uncomfortable for individuals with sensory sensitivities

 

What Is the Best Filling Material for a Weighted Blanket?

Each filling material has its pros and cons. Besides knowing its advantages and disadvantages, here are other factors to consider when choosing a weighted blanket filling material:

Sensitivities

Some fillings, like steel beads and rocks, may rustle when moved. This noise can be bothersome for people with auditory irritations. Those dealing with sensory sensitivities may also get irritated by uneven weight distribution. That said, consider your sensitivities and steer clear of filling materials that tend to cause discomfort.

Allergies

Some fillers are made of plastic or organic materials. If you have sensitive skin or allergies to artificial or organic ingredients, don’t buy weighted blankets filled with poly pellets, dry foods, and sand.

Budget

Filling materials can be cheaper or more expensive, depending on their manufacturing process. Consider your budget and check options that offer the best quality for the price to get the most out of your blanket.

Convenience

Clean bed linen makes for an ideal sleep environment. This is why choosing a machine-washable and dryer-friendly filling material is essential.

If you tend to sweat at night, go for beaded fillers since they’re easier to wash. Also, don’t wash blankets filled with porous materials, like sand, beans, and grains, to avoid having bed linen with decomposing fillers.
