Features

  • FULLER, FLUFFIER PILLOWS: Plumps 18x18 covers with a soft, rounded shape that springs back, so your throw pillows look full and freshly styled on any couch, sofa, or bed.
  • SOFT, FLUFFY FILL: Premium polyester filling is plush yet supportive, giving every insert a full, high-loft feel that holds its shape and resists going flat over time.
  • TRUE 18x18 FIT: Sized to fill 18x18 pillow covers. For a plump, full look, pick a cover the same size or 1 inch smaller so the corners stay sharp instead of saggy.
  • HYPOALLERGENIC COMFORT: The hypoallergenic fill is a gentle pick for sensitive homes; fluff by hand now and then to refresh the loft and keep pillows looking full and even.
  • VALUE SET OF 4: Four matching inserts to refresh a whole couch or room at once. Great for couch, bench, nursery, and bedroom refreshes, backed by Foamily support.

Description

What size pillow insert should I buy? For a standard fit, choose the same size as your pillow cover. For a fuller, designer look, size up by 2 inches, like a 20x20 insert for an 18x18 cover. Are these pillow inserts soft? Yes. Foamily pillow inserts are made to be soft, fluffy, and comfortable, while still giving decorative pillow covers a full look. Why do the inserts look flat when opened? The inserts may arrive compressed for shipping. Shake, fluff, and let them expand before placing them inside your pillow covers. Where can I use these pillow inserts? They are great for couch pillows, bed pillows, sofa pillows, accent chairs, nursery décor, office décor, and decorative pillow covers. Are these good for replacing old pillow inserts? Yes. Foamily inserts are a simple way to refresh flat or worn throw pillows and give your pillow covers a cleaner, fuller look.

    • Perfect fullness for throw pillows
Size: 18x18 Inch Number of Items: 4
Review Image by Naomi Smith
Bought these pillow inserts for my daughter’s decorative pillows and they worked out great. They’re nice and full without being stiff, so the pillows hold their shape and don’t look flat or saggy. They fit the covers perfectly and give that “fluffy but still comfy” look. After fluffing, they bounce right back and still look great on the bed. Quality feels solid and not cheap. If you’re tired of throw pillows looking limp, these inserts are a great upgrade. I’d definitely buy them again. ... show more

Review Image by John
First thing I noticed was the lack of any of the "usual strong odors" that typically come from vacuum packed pillows after they were unsealed. Very much appreciated! Tumble lowest heat, and were ready to go in minutes. These do fit an 18" case, but as they mentioned, it's best to get an insert 2" bigger than the case you have for a fuller look. You will have floppy corners and a flatter throw appearance otherwise if you use a throw case of the same size. I put one of these in one of my spare 18x18 cases to showcase this. Polyfill does not fill the same way that foam does! Purely meant as a decorative insert ONLY. They do not provide any back or side support on their own. If you need a supporting throw pillow insert for your couch or bed, you will want to look for one that offers a zipper with adjustable fill, or a material meant to offer that support. Not a demerit in my case. These were meant for a piece of furniture that will use these inserts for their decorative naturate anyway. These just got here before the covers did. ... show more

    • empty corners
Size: 20x20 Inch Number of Items: 1
I bought the 20x20 pillow to go inside an 18x18 cover. The corners on the pillow itself are not filled out, so when you put it in the cover the corners are a little empty, even when using the smaller cover. In fact, if you look closely at the product picture, the bottom corner of the pillow is sort of folded outward - that is because it is empty corner and sort of just flaps/hangs loose. I tried to work the stuffing into the corners better, but it just doesn't work. I am hoping over time as it is used more I will be able to work it in better. It is fluffy, but flattens quickly. Not good if you actually want or need some definite support, but good enough to sit pretty and look nice, as a decorative pillow. I would not consider it a premium quality item. It is acceptable, though. Definitely buy a smaller size cover than the pillow. You always want to go with the smaller cover to give you a more plump pillow, but especially with this one with the empty corners, you definitely need the larger size pillow to try and fill it out more. And remember, even though it is really plump to start, it is going to flatten and loosen up over time, so even if you do not like a more plump firm pillow, you will want it that way initially or else you will end up with a sloppy, flat pillow and a lot of excess room in the cover once the pillow flattens down some. ... show more

I bought my son a pillow case that had loving sayings on it to him but it came without a pillow case so I bought a pillow to go inside it. This one worked perfect. It is good quality and soft, I did not wash it.

    • Fine for Throw Pillows, But Very Flat

These pillow inserts are okay for the price, especially since you get multiple pillows in one pack. However, they are much flatter than expected and don't have the fluffy, full look shown in the product photos. The outer fabric that holds the filling is also very thin and somewhat see-through. It doesn't feel particularly durable and seems like it could rip fairly easily with regular use. After giving them time to expand, they still remained pretty flat. That said, they work well enough for decorative throw pillows and basic couch decor. If you're looking for plush, supportive pillow inserts, these probably aren't the best choice. For simple throw pillow use and the price point, they're acceptable. Size is exactly what it states.There is no fluffiness, and I would definitely not utilize them for any support or sleep quality ... show more
