    • Soft, fluffy, and high-quality pillow insert🤗🥰

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

    • Better than down!
Size: 20 Inch by 20 Inch
Review Image by kristy garcia
Tired of re-fluffing your old down pillow? Want a replacement to feather down pillows with all the comfort but without the mess and smell? This pillow is for you! I replaced my old feather down pillow with this one. I can tell you I do not miss the feather shafts poking out here and there or down feathers scattered all over when I would take the cover off for washing. This pillow is plenty plush, fluffy, nice and thick, plenty big (true to size) and the quality feels just as good as the down pillow I replaced, if not better. It is more comfortable to rest your head on than the down pillow and definitely holds its shape much better. The down pillows flatten fairly quickly and have to be re-fluffed constantly after use...this pillow holds it shape without being rigid. Freshness - this pillow does not have that "feather" smell. It has no smell at all as a matter of fact. I would definitely buy this pillow again. ... show more

    • THE PERFECT PILLOW INSERT!!!!
Size: 18 Inch by 18 Inch x 2
Just what I was looking for in a pillow insert. They are well made and just the right fill. Nice and cushiony. Also Love all the size options. Using them now for all my pillows.

    • 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

    • Buy it!
Size: 12 Inch by 24 Inch
This pillow is fabulous! It's dense, but soft. It has weight to it, and is well made. It holds up to use much better than another brand I bought. When the other brand wears out, I'm coming back for more of this one.

    • Nice pillow
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 .

    • Great to use as a body pillow
I love this pillow. The 14 x 36 is the perfect size to use as a body pillow. It's very fluffy and full and provides the perfect amount of support for side sleeping. Does not go flat like many other pillows I've tried. The fill is slightly heavy but not a deal breaker.

    • 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
