Synthetic Down Pillow Inserts Weight Chart

  • Synthetic down pillows weigh about 2.5 times the weight of a traditional pillow.
  • Fiber is the most expensive part of a pillow, if you see a competitor selling a synthetic down pillow for slightly more than a traditional pillow I would be cautious of the type of filler they are using and if it really feels like down.

Perfect! 03/22/2019
By Sheila Peters
I have purchased the pillowflex down alternative pillow inserts and I love them. If you follow the directions for sizing you will get a nice plump fit and this material holds the chop if you are looking for that...just be sure that your cover is not too snug. The insert cover material is white, very smooth and tightly woven so it easily slides into the pillow cover. There is no odor. The filling extends to the corners for a nice full look. I put mine in the dryer on air fluff for ten minutes and it puffed right up. Highly recommend these inserts. I plan on buying them for my pillow covers from now on. Made in USA is a priority for me and I’m thrilled to be able to purchase such excellent quality. If you purchase one of these you will never go the cheap imported route again!

Best synthetic down inserts EVER 01/17/2022
By Susan Woods
I have been purchasing these inserts for over 5 years. The two I have in my home are 4 years old, sit on the two chairs that get used every day - many times a day- and have retained their shape perfectly. They are heavier than real down or poly fill but so soft yet substantial suppport.
I have also purchased the feather/down inserts and the poly. Both are great although the feather inserts went a bit “flat” within 4 years with frequent use. I work at an upholstery shop and these are our inserts of choice. Only con is the cost of shipping! That tends to almost double the price
IMPORTANT TO NEW BUYERS: Use the recommended sizing chart to avoid disappointing results!

Top-shelf faux down inserts 12/02/2021
By Blair Baez Velvet Studio
We have been purchasing synthetic down inserts from Pillowflex for our line of high end decorative pillows for years now. Most of the pillows we make are between 12x20" and 24x24" and we agree with the Pillowflex recommendation that inserts sized two inches larger than the cover produce excellent results. We get constant feedback from experienced customers that these are the best inserts in their collection. The weight, fill, and consistency of manufacturing is superb. If you want a luxurious finish to your decorative pillow, THIS is the insert to put in it!

Another home run! 05/07/2019
By Sheila Peters
I’m so happy with these pillow inserts. They are reasonably priced, generously sized, soft but firm and hold a karate chop perfectly. I use them as sham stuffers and I would highly recommend them to anyone looking for an insert that is a down alternative. I personally think these respond better than down because they do not go flat . I make purchasing USA made goods a priority and I was so happy to find pillow Flex! This was not my first order and it will not be my last. I plan on replacing every down insert I own! Don’t hesitate to buy them.

Amazing Inserts 08/30/2019
By Karla Dickey
I am a small Etsy shop owner of custom designed pillow covers. I had tried some Amazon inserts for a similar price but they were worn out after about a month. Pillowflex down alternative inserts are excellent quality, great, sturdy feel, soft and luxurious quality. We have little children and these inserts have held up well and I’ve gotten great feedback from my customers. These inserts are an excellent price for the quality. I also like supporting family owned businesses with USA made products! Thank you, Pillowflex!

best pillow inserts ever 05/31/2024
By leida rodenburg
As a fabricator of pillows, I have to say that the synthetic down alternative are the best on the market. They act as down with out the risks of allergies. The Pillowflex company turn around time is fast and reliable! Prices are very reasonable. Now I agree with some of the concerns about the expensive shipping cost, but even with that they are still less expensive and best quality around. I have been a repeat customer and will continue to do so! Just love them

Synthetic Down Alternative 09/27/2021
By Mae Garrett
Love these inserts for my couch and chairs! They are so soft, yet hold the shape and you can karate chop them, and it stays also. After looking everywhere in stores and online, these were the best deal that I could find. I am glad I went with the Pillowflex brand. I am very happy with the quality and pricing. I ordered them and they arrived the very next day! No issues with packaging either. I am planning to order some for all my bedding next! These are the best!

Quality product 01/28/2022
By Lyndi
I am very happy with these synthetic down alternative pillow inserts for my Potterybarn Euro pillow shams! I had tried other pillows, but these shams never seemed full and always looked sad and droopy. These pillows fill out the shams perfectly--according to the sizing guide!--and look FULL and are so comfortable to lean against when sitting on the bed. I'm so thankful I gave them a try. I'm ordering more in different sizes now & updating all our droopy shams!

By Eric Horner Interiors
We are an interior design firm and found Pillowflex online. We were so pleased with your synthetic down inserts that we have to decided to switch to Pillowflex for all our pillow inserts from here on out! The outer cover is a great material, the form has wonderful loft and weight with the perfect pillow chopability! Hands down better than the 10/90 forms we were buying from another source and without all the loose feathers. Highly recommend.

By Shannon Farrey
I have been ordering Pillowflex's synthetic down inserts in several sizes since 2013, and have been happy with every purchase. I make pillow covers to sell retail, and I've received many compliments on the pillow's quality from returning customers. The shipments always come faster than expected (even during Covid.) I'm so glad I found Pillowflex - They have made buying pillows easy - I know I'm getting a quality product at an EXCELLENT price.
