7 Best Throw Pillow Inserts and Filling That Last

Published on

The best couch in the world can feel lonely without a couple of comfy throw pillows. While some believe throw pillows just create more clutter, we disagree because they serve two very important purposes: aesthetic and function.

The best throw pillows not only make your space look comfortable and inviting but they can also serve as neck, back, and leg support. If you’re looking to add some life back into some old throw pillows or simply increase the comfort of some new purchases, you need to know about throw pillow inserts.

What is a throw pillow insert? It is simply an additional layer of stuffing inside the throw pillow cover. They come in different sizes and can help make your pillow more comfortable.

Throw Pillow Insert Materials

There are a few different types of throw pillow inserts you should be aware of:

  • Down throw pillow inserts are stuffed with feathers of birds such as ducks. This natural material is breathable, naturally hypoallergenic, lightweight, and durable.
  • Fiberfill has a similar softness to down but is cheaper, making it a common material for a throw pillow insert. Fiberfill pillows are machine washable and hypoallergenic.
  • Cotton is another common material. It is also hypoallergenic and durable. However, cotton throw pillow inserts are usually firmer compared to down and fiberfill.
  • Mixed throw pillow inserts are also common. Some manufacturers use down and fiberfill, while others use a combination of different materials to achieve the desired comfort, softness, or firmness.

Polyester is a good choice if you’re not sure what type of throw pillow insert to buy. Aside from being affordable, you can also choose the level of firmness.

They provide relief to allergy sufferers because they protect against common allergens like dust mites.

Pure down throw pillow inserts can be expensive, so this product from Edow is a good choice for those who are looking for a more affordable alternative.

Just like down, microfiber polyester is versatile, soft, and fluffy, making it a good alternative to the more expensive down. These throw pillow also inserts easier to maintain compared to down-filled inserts. Just like fiberfill, you can spot clean it or wash it in the washing machine. Unlike down, however, microfiber polyester dries more quickly, and its elastic properties make it less susceptible to clumping. This means your insert should stay feeling fluffy, soft, and comfortable over extended periods of time.

This Edow product provides medium support, so it is not too soft or too firm. In other words, it is in the Goldilocks zone for throw pillow inserts.

Yes, many pillow inserts are easy to maintain, but what if they get soaked? Here’s where water-resistant lining can save the day. Even the hardiest polyester filling can admit defeat if they are constantly getting wet, either due to the elements or water from the pool. Just like any other material, throw pillows need to dry completely so that they can retain their shape and softness.

Luckily, waterproof materials can protect the filling inside, so maintenance is very low. Put on a waterproof throw pillow cover for extra protection and to make your inserts last longer.

Waterproof fillings do have a crinkly feel, so they are definitely not the most comfortable. However, you can’t beat them when it comes to practicality.

Best Throw Pillow Insert Buying Guide

You are spoiled for choice when it comes to throw pillow inserts. That means it can be challenging to figure out which pillow to buy. Luckily, we have a short guide to make the choice easier for you.

Here are some things to keep in mind when selecting your next throw pillow insert:

  • Material – Are you looking for soft or firm throw pillows? If soft, you may opt for down. Alternatively, a memory foam pillow will provide added support. If you have allergies, stick to hypoallergenic filling like fiberfill or memory foam. If you prefer down filling, check to see if it has been treated to protect you from allergens.
  • Size – this is another important consideration for throw pillow inserts, as you need to buy the right size for your existing pillows. Check the measurements and buy accordingly.
  • Price – you don’t have to buy the most expensive throw pillow insert in order to achieve the look you want. There are many budget-friendly options that still offer comfort and softness.
  • Functionality – finally, think what your throw pillows are for. If they are only there for decoration, then you can easily get away with fiberfill inserts. However, if you need them for additional support, we suggest investing in memory foam inserts.

Best Materials For Throw Pillow Inserts

Materials are a personal preference. However, we prefer to choose materials based on what you intend to use your throw pillows for.

  • Decorative – For this purpose, inexpensive materials like fiberfill with a polycotton covering will do the job. They are comfortable but affordable. In other words, they provide the best value for money.
  • Support – people needing additional help for injuries should seriously consider the materials of their inserts. For those with neck injury or neck pain, throw pillow inserts with memory foam material can greatly alleviate pain. Side sleepers should consider firmer inserts in order to keep their spine aligned while sleeping.
  • Versatility – people who want versatility are usually happy with fiberfill. It is affordable, comfortable, and easy to maintain. They can be used in the sofa, lounger, patio, and other areas of the house. Pop a waterproof cover on the insert, and they can even be used outdoors.
