Solid choice for pillow inserts!

Nice quality, firm yet soft. Really the perfect pillow for what I needed. Fit perfectly in my 12x20 cover. A solid choice at a good value!

Glad I chose these Sturdy, Fluffy Pillows
Color: White, Size: 18x18 Inch
Took me forever to decide which pillows to buy....Price won out. There might be better out there, but I really can't see how. They plumped up really nicely. I once learned from a manager at a big box dept store when purchasing a goose down pillow how to 'activate' the pillow. Basically, he violently threw the pillow down onto the floor, then proceeded to beat the tar out of it....That's how it's done. I think many ppl don't do a good enough job when they get their pillows. I watched several videos from ppl who have purchased this type of pillow. And quite frankly, they do not know what they are doing....My pillows are very plump and awesome. I purchased the 20" squares and then chose 18" pillow covers to stuff them into. Perfection. Fat, soft, soothing pillows. Me and my Doggo are quite happy to lounge around on these durable puffs of fluffiness.

Perfect
Color: White, Size: 12x12 Inch
These are great quality pillow inserts. They arrived very securely vacuum packed. Be careful when opening. I followed the directions and they were fluffy within a few minutes. They are small, but this is the size that I needed. I am glad that I didn’t order a few inches larger, as recommended by many. They fit perfectly in my 12x12 inch pillow covers. I would recommend this brand and seller for purchasing this product.

Fluffy and Supportive Pillow Inserts
Color: White, Size: 12x20 Inch, Color: White, Size: 12x20 Inch
I used these pillow inserts for my couch cushions, and they’ve worked out really well. They give my throw pillows a nice full look without being too stiff or flat, which makes the couch feel more put together and comfortable.
Filling quantity: They’re nicely filled and give good shape without feeling overstuffed.
Durability: They seem well-made and hold their shape well even after daily use.
Color: Clean, bright white that works well with different pillow covers.
Appearance: They make my decorative pillows look fluffy and full, giving the couch a more finished look overall.
