What are Weighted Blankets Made of?


Weighted blankets have been ALL over the internet as of late.

Pretty much every publication -- from NBC News to HelloGiggles -- is talking about these blankets, reviewing them, and discussing their pros and cons.

If you’re keen on purchasing your first ever weighted blanket, we’ve put together a handy guide that addresses some questions that we commonly get about these blankets:

  • What are weighted blankets made of?
  • What are weighted blankets filled with?
  • What is inside a weighted blanket?

Read on to find out more!

What are weighted blankets made of?

In a nutshell, weighted blankets consist of three components -- the blanket, blanket cover, and fillings or stuffers which weigh the blanket down.

First up, let’s talk about the blanket itself:

Most weighted blankets come with some sort of fabric padding to provide cushioning between the filling and the user’s body. Typical paddings include polyester, cotton, fleece, and chenille.

We also know of some weighted blankets which are made of hand-knitted weighted weaves (the weaves are what add weight to the blanket, and these blankets don’t feature any fillings). That said, these are pretty rare, and we can’t vouch for their effectiveness.

On top of that, most weighted blankets feature a cover that’s either sewn-on or removable.

Fabrics used to create weighted blanket covers include cotton, flannel, fleece, minky, rayon, linen, and microfibre; for ease of washing, we recommend getting a blanket with a removable cover.

So, the question is… what fabric should you look for when purchasing a weighted blanket?

Now, this really boils down to personal preference. Each fabric comes with its own advantages -- cotton, for example, is soft and breathable, and microfibre and minky are warm and great for snuggling up in.

Here at Hush Blankets, our inner weighted blanket is made of a super comfortable microfibre material, and we use a super-soft minky for our blanket cover.

If you’re not 100% sure what minky is, this is basically a silky and soft fabric that’s commonly used in creating baby blankets, bathrobes, quilt backings, and similar items. Here’s how it looks:

What are weighted blankets filled with?

Okay, moving on to weighted blanket stuffers. They are three main categories of stuffers used in weighted blankets, and these include:

  • Plastic poly pellets
  • Micro glass beads, and
  • Steel shot beads

We’ll walk you through each of these weighted blanket materials and stuffers in detail, so you can figure out which is the best fit for you.

First up, plastic poly pellets are small round plastic beads that feel like pebbles. These are made from polypropene, which means that they’re considered safe and non-toxic.

Note that as compared to other stuffings, poly pellets aren’t the smoothest or most comfortable. If your blanket isn’t properly constructed, it could feel lumpy or uneven.

On top of that, plastic poly pellets can sometimes give off an off-putting odour; that said, this should dissipate quickly after a few airings.

If you’re considering of getting a weighted blanket that’s filled with plastic poly pellets, try and look for a brand that uses high quality poly pellets (such as pellets made out of 100% virgin polypropylene).

At the same time, you should also check if the pellets can withstand your washing machine / dryer -- not all poly pellets have high temperature ratings.

Next, you can also find several weighted blanket brands that come stuffed with micro glass beads (texture-wise, these resemble grains of sugar).

As compared to plastic poly pellets, micro glass beads are a lot smaller, and this allows them to sit more densely within the blanket.

Generally speaking, weighted blankets filled with glass beads are thinner than blankets filled with poly pellets, and they also tend to lie more smoothly on the user’s body.

Here at Hush Blankets, we fill our weighted blankets with glass sand, which is basically like micro glass beads, but EVEN smaller. This glass sand is contained within your weighted blanket in more densely packed pockets, in order to evenly spread the weight across your body.

Last but not least, you’ll also find weighted blankets that are stuffed with steel shot beads, which are essentially micro steel balls which are heat-treated.

On the bright side, these steel beads are extremely smooth to touch, which means that they don’t retain a lot of dirt between them.

However, steel beads tend to be slightly larger than glass beads, and they can be a tad lumpy and noisy, which isn’t ideal.

Miscellaneous stuffers: sand, grain, pebbles

If you do your research online, you’ll find that aside from the three categories of stuffers we discussed above, there are a handful of unorthodox weighted blanket materials such as sand, hulled crop grains, pebbles, etc.

Here’s a word of advice… should you see a weighted blanket brand that uses these non-traditional stuffers, avoid purchasing from them at ALL costs.

Why do we say so? Well, these stuffers are a lot cheaper and lower-quality than poly pellets, glass beads, or steel beads, and no legitimate company would dream of using them in their weighted blankets.

Take sand, for example. Sand clusters up inside the pockets of blankets (instead of spreading out, like how glass beads or poly pellets do) -- so if you’re using a weighted blanket filled with this stuffer, it’s highly likely that you’ll see large and uneven bumps in the fabric.

On top of that, sand expands when it comes into contact with water, and this makes washing your blanket a huge ordeal.

Then there’s pebbles and aquarium stones, which also don’t work as effectively as poly pellets, glass beads, or steel beads.

The main problem with pebbles and aquarium stones is that they’re organic, porous materials. Once these materials come into contact with water, it’s hard for them to dry out completely.

In other words: once you wash a weighted blanket filled with pebbles or aquarium stones, the blanket will retain moisture, and it’ll eventually start to get mouldy.

How about the blankets made using hulled crop grains (such as buckwheat)?

Like sand, these grains expand when they come into contact with water, which makes washing your blanket problematic.

In fact, if you try to wash a weighted blanket filled with buckwheat, the buckwheat within your blanket will probably begin to rot. Yikes… you definitely don’t want that!
