Loved it
Bought this for my 3 year old son and if it’s perfectly on his toddler, bed would definitely recommend. I love the fluffy and cooling effect. It gives is very soft. It feels amazing. Especially for a toddler very comfy.

Great pillow & Machine Washable
A little on the firm side at first, but it's getting softer with a little use.

Fluff this in the dryer and this is the perfect pillow!
I bought throw pillows from this same brand and was disappointed until I read a tip in the reviews to place them in the dryer on fluff for about 20 minutes. That did the trick and one saved me after a rotator cuff injury. I used it for months to prop my arm up and prevent pain in my shoulder. I loved it so much I decided to see if this brand made a pillow for sleeping and was excited to find they did! This one took two rounds in the dryer on fluff, but I couldn't believe how soft and fluffy it got. I have been getting the best sleep ever since. If you get this pillow, I highly suggest throwing it in the dryer. It makes a huge difference!

Comfortable
This is the fluffiest pillow I have ever bought. I bought it for my 5 year old. He is extremely happy with it and makes him feel like he finally has a big boy pillow that supports him when he sleeps. I might buy one for myself. Defiantly a good purchase.

Fabulous
This is a fabulous pillow. I love it. I recommended wholeheartedly. It is however, large larger than I was expecting. Fortunately, I had a large pillowcase that fits it.
