By the end of this article, you’ll be an expert on all things throw pillow inserts! So, what are you waiting for? Let’s get started!

What is a Throw Pillow Insert?

A throw pillow insert is a type of pillow that is used to fill a decorative pillow cover. Throw pillow inserts come in a variety of shapes, sizes, and materials. Most are rectangular or square, but you can also find circular and pillows in other shapes.

The most common materials for throw pillow inserts are down and synthetic down. Down is the softest and most luxurious option, but it can be more expensive. Synthetic down is a good alternative if you’re looking for something more affordable.

When choosing a throw pillow insert, it’s important to consider the size of your pillow cover. You want to make sure the insert is slightly smaller than the cover so it fits snugly inside. Also, keep in mind that some materials, like down, will expand when they’re fluffed up, so you may need to get an insert that’s slightly larger than your cover to account for this.

The Different Types of Throw Pillow Inserts

There are four main types of throw pillow inserts: down, synthetic down, polyester, and foam.

Down pillow inserts are made from the soft undercoating of ducks or geese and provide a luxurious, soft feel. They are also the most expensive option. Synthetic down pillow inserts are made from man-made materials that mimic the softness of natural down and are a more affordable option. Polyester pillow inserts are filled with polyester fiberfill and have a firm, yet bouncy feel. They are a popular choice for decorative pillows because they hold their shape well and are easy to care for. Foam pillow inserts are made from stiffer foam that is ideal for support pillows. They can be customized to fit any size pillowcase and provide firm, consistent support.

What Fillings are best for Throw Pillow Inserts?

There are several types of fillings that can be used for best throw pillow inserts, each with its own advantages and disadvantages.

Down: Down is a popular choice for pillow inserts because it is soft and bouncy. However, down can be expensive and is not always hypoallergenic.

Polyester: Polyester is a synthetic fiber that is less expensive than down, but it does not have the same level of softness or bounce. It is also not as breathable as down, so it may make you sweat more at night.

Memory foam: Memory foam conforms to your body and provides support for your head and neck. However, memory foam can retain heat, so it may not be the best choice if you tend to sleep hot.

Buckwheat hulls: Buckwheat hulls are a natural filling that provides good support for your head and neck. They are also adjustable so you can add or remove filling to get the perfect level of support. However, buckwheat hulls can be noisy and they may not be as soft as other options.

How to Care for Your Throw Pillow Insert

Assuming you have already purchased your throw pillow insert, there are a few things you should do to keep it in good condition. First, if your insert came in a plastic bag, take it out and fluff it up. This will help to restore its shape. If it is still looking flat, you can try putting it in the dryer on low heat for about 10 minutes.

Once your insert is fluffed up, you should put it into a pillowcase. Make sure the pillowcase is big enough so that the insert can move around a bit. This will help to keep the insert from getting misshapen again. You can also use a pillow protector, which is like a pillowcase but has an extra layer of protection.

If you need to wash your throw pillow insert, make sure to use cold water and a mild detergent. Do not put it in the dryer – instead, let it air dry. Once it is dry, fluff it up again and put it back in the pillowcase or protector.
