    • Soft, fluffy, and high-quality pillow insert🤗🥰
Size: 14 Inch by 14 Inch

I’m very impressed with this pillow insert. The synthetic down filling feels incredibly soft and plush, giving it the look and comfort of a real down pillow without the feathers. The 14x14 size fits my decorative pillow cover perfectly and provides a full, luxurious appearance. The insert fluffed up nicely right out of the package and maintains its shape well after daily use. It feels comfortable whether used as a decorative accent on a sofa, chair, or even for extra support while relaxing in bed. The fabric is smooth, the stitching is well-made, and the overall quality exceeded my expectations. If you’re looking for a soft, well-filled pillow insert that looks high-end and feels comfortable, this is an excellent choice. ... show more

    • Buying more in different sizes!
Size: 22 Inch by 22 Inch
I’m very happy with the Pillowflex Synthetic Down Pillow Insert (22x22). The fill is soft, fluffy, and provides a nice balance of comfort and structure. It has that “down-like” feel without being too flat or overly stiff, which is exactly what I was looking for in a decorative throw pillow. One of the biggest positives is how well this 22x22 insert fits into a 20x20 pillow cover. It gives the pillow a very full, high-end look—no sagging corners or underfilled appearance. The result is nicely plump and polished on the couch. The quality feels solid, and it holds its shape well after fluffing. My only small reason for four stars instead of five is that it does compress a bit over time and needs occasional fluffing to keep that full look. Overall, this is a great value pillow insert—comfortable, soft, and perfect if you want a fuller look when sizing up inside a 20x20 cover. I would definitely buy these again. ... show more

    • Excellent Quality pillow insert
Size: 26 Inch by 26 Inch
I absolutely love these pillow inserts! They are incredibly soft, plush, and comfortable while still giving my pillows a full, high-end look. I specifically wanted a synthetic down insert because I was tired of feathers poking through other pillows, and these are exactly what I was looking for. No feathers, no mess—just soft, cloud-like comfort. I was so impressed with the first one that I immediately came back and purchased a second. That says a lot about the quality! Another huge bonus is that they’re made in the USA, which makes me feel even better about supporting this company. The quality, comfort, and craftsmanship have exceeded my expectations, and I will definitely continue purchasing from this brand in the future. Highly recommend if you’re looking for a soft, luxurious pillow insert without the hassle of real feathers! ... show more

    • High-End Designer Look Without the Feather Mess
Size: 24 Inch by 24 Inch
Top quality with a truly luxurious feel. After years of dealing with feather inserts and quills constantly poking through, making my pillows uncomfortable and nearly unusable, I decided to do some research and found Pillowflex. These inserts are exceptional—plush, substantial, and beautifully made. They have a nice weight to them and instantly elevate the look and feel of your pillows. Don’t waste your money on cheaper alternatives; these are absolutely worth the investment. My only recommendation is to double-check your pillow cover measurements before ordering to ensure you select the right size. Other than that, I couldn’t be happier with my purchase. ⭐⭐⭐⭐⭐ Worth every penny. ... show more

    • Great Quality Pillow Insert – Buying More!
Size: 22 Inch by 22 Inch
I was pleasantly surprised by the quality of this Pillowflex Synthetic Down Pillow Insert. It's soft, fluffy, and keeps its shape really well while still being comfortable to lean against. It gives my pillow cover a full, high-end look without feeling stiff. I originally bought one to try, but I liked it so much that I'm ordering more—not just for my decorative pillows, but for my bed as well. If you're looking for a well-made, comfortable pillow insert, I definitely recommend this one. ... show more

Size: 20 Inch by 20 Inch x 2
They are nice quality and soft ... however , they are 2" smaller than advertised, so the pillow cover is too big on them .

I have bought this pillow form twice! It is my grandchildren’s favorite pillows to snuggle with on my couches. This synthetic pillow form fills up my pillow-covers perfectly and makes them the perfect support when sitting in the couch. The filling is like a cloud to lean pack on. It gives the right support behind your back too. My picture is the pillow cover that has this synthetic down pillow insert in it. It’s just huge and perfect! ... show more

    • Perfect pillow!
Size: 27 Inch by 27 Inch
This is the perfect pillow. It has some weight to it probably because it’s filled with high quality filling and it has a good bit of it. It’s moldable, does the chop well and is so comfy! I feel like these will last forever! I started with purchasing two and loved them so much, I replaced my Euros on my king and all my pillows in the living rooms in both houses. ... show more
