    • Softness, Size, Quality
Size: 12 Inch by 16 Inch
The pillow is as stated: nice and soft, very well made cover on the pillow and perfect size for behind the neck. It conforms to the shape you want and is very comfortable. I use it at night in addition to my regular pillow to lift my head up a bit. It helps with my allergies and migraines. I do recommend this pillow. I also bought a separate pillow case since I use it daily, but it’s not absolutely necessary, but I would suggest it. Great price, Terrific pillow! ... show more

    • 26x26 pillows for couch: THE BEST ONES, LOOK NO FURTHER
Size: 26 Inch by 26 Inch
If you are looking for pillows to put on a couch these are the ones to get! I got another brand and they are thin and not much support. I am returning them. THESE ARE Fluffy, keep their shape, provide support and fit in a 24x24 cover. I cannot say enough how great these are!! They are worth the price and are wonderful. ... show more

    • Perfect pillows!
Size: 22 Inch by 22 Inch
These pillows are perfection!! They fit my new pillow covers perfectly. I got them a little bit bigger than the covers and the pillows are nice and fluffy. I like how they are cruelty free synthetic down. They are soft and cozy and look great on my sofa!

    • High quality & soft yet full
Size: 28 Inch by 28 Inch x 2
Pillows are very good quality for the price. I got 2” larger size than my sham size for a perfect full fit. Very pleased. These look great on our bed.

    • Great pillows!
Size: 24 Inch by 24 Inch x 2
Pillows are incredibly comfortable, they have a nice weight to them, just the right amount of firmness! I have yet to see any flattening, and are easy to fluff up after laying on, while they are “synthetic down filling” I have a hard time telling the difference! Would 100% purchase again.

    • An objectively good all around pillow
Size: 16 Inch by 26 Inch
I've been cycling through throw insert vendors on here and Pillowflex was one of the last I hadn't tried due to the reviews being all over the place. Then I got a single cover with an odd sized insert and figured, "well..." Pillow arrived in a plastic bag marked with a notice "Vacuum sealed! Do not open! Will expand on opening!" I opened the end flap and the pillow asserted itself by expanding slightly. I pulled it out of the bag, gave it a shake or two, and it expanded another 10-15%. It resisted being stuffed (and not in a good way, think liquid-filled stress ball) into a pillowcase 2x2 smaller, and afterwards was put into the dryer on low for 30 minutes. Upon removal from the dryer it hadn't inflated much more and now fills the case very nicely, picture-perfect almost. The heft is substantial without being overbearing. The pillow gives under pressure but eventually provides support. It rebounds quite nicely, lands with a gentle thud when tossed, and is somewhat reminiscent of actual down. Objectively, by the metrics, and all around - this pillow is about perfect. I can't really find a flaw or fault with it. Good engineering and a good value for the price. It's likely to perform for you unless you need something really flat. Subjectively, the best way I can describe it is that this pillow tries to do everything well and falls into some sort of weird pillow uncanny valley. Like that liquid-filled stress ball I mentioned earlier. It's cool and it works, but it just doesn't feel... natural... ... show more

    • Good quality.

Very good quality! Surprisingly heavy, but also soft. It should last a very long time.
