Most Luxurious

Pillowflex Synthetic Down Pillow Insert

Let’s be real – who doesn’t want to feel like they’re love laying in a giant fluffy cloud? Well, this pillow insert is probably the closest thing to a cloud that you’ll ever find. Cuddling up to a pillow filled with Pillowflex’s Synthetic Down Pillow Insert is one of the most luxurious experiences you will ever have.

This pillow insert is filled with a faux down polyester fiber filling that has the same feel, weight, and characteristics of traditional down, but at a fraction of the cost. It even has that “karate chop” look that you get with natural down pillows. Unlike poor quality pillows that use dry fibers, this pillow inset uses a slick polyester fiber to keep the pillow’s filling smooth and lump free. Plus, this pillow insert is hypoallergenic, odorless, and free of flame retardant chemicals, so you can use it in any room in your house without having to worry about allergens or harsh chemicals affecting your loved ones.

What to look for in your next 18 x 18 pillow inserts

When shopping for pillow inserts, consider the following factors:

  • Feel. One of the most important factors when purchasing pillow inserts is the feel. Before you buy your inserts, make sure that you have established what your preferred feel is. Do you want a soft and fluffy pillow for naps? Are you in need of lumbar support? Do you prefer an overstuffed pillow? Are they purely decorative or will your pillows be used while you sleep?
  • Number of inserts. Are you looking for just one or two inserts? Or, are you wanting to purchase multiple inserts? Decide roughly how many you want to buy as this will help you understand how much you are willing to spend. Also, you may want to search for inserts that come in larger quantities instead of just one or two packs. 
  • Cost. Now that you know how many inserts you need, go ahead and establish a budget. Figuring out how much you are willing to spend total will give you an idea of the price range of the pillow inserts you are looking for.  
  • Size. Some people prefer a very tight pillow that is packed with filling. In general, a pillow insert is going to decrease in size about 10% from the size listed. If you don’t want a lose pillowcase, make sure your shams are a little smaller than your pillow insert.  

FAQs

What size pillow sham should I use with my 18” x 18” pillow inserts?

In general, it is recommended to use a pillow sham that is 1” to 2” smaller than your inserts. So, for 18” x 18” pillow inserts, you will want a 17” x 17” pillow sham. 

Do I have to use a pillow sham with inserts?

Not if you don’t want to! It is completely up to you and your personal preferences. If you get a pillow insert that has a nice, durable cover and you like the way it looks, then why not skip the sham altogether?

Conclusion

Pillow inserts provide you with the freedom to customize your room’s décor without having to sacrifice comfort. Thankfully, finding high-quality pillow inserts does not have to be a challenge nor does it have to break the bank. Make sure to use our picks for the best 18” x 18” pillow inserts to find the perfect inserts for your needs and start lounging in style.
