Figured I would wait a month or 2 before leaving a review. At first. The pillow was great. Very comfortable. Held up nice. Nice and firm and gave great support. After a month. It started to flatten out. Had to re-fluff it only to have flatted out faster this time. Now no matter how many times I fluff it. It doesn’t give the proper support any longer. I’ve bought 2 of these and they are identical. So it can’t be just a fluke for the 2 i have. I’m regretting the purchase as the price was fair when I bought them. But not any longer as they are not the same.

Best pillow ever!!!

Size: Sapphire Queen

I have actually tried dozens and dozens of pillows in my life, and dozens in the past three years, but this is it. Some cheap, some very very expensive, and some very famous brands. This one beats them all. So awesome and comfortable (side sleeper). I tried one and loved it so much I ordered a second right away. It is exactly what I've been searching for forever!!! Stays in shape, extremely comfortable. Only thing is you definitely need a 32" pillowcase to cover it, and I wish they made a 34" pillowcase, but no luck. I used the pillow the same night and it's definitely worth the money. No neck pain, super squishy but supportive, and no odor.

Great pillow

Size: Sapphire King, Size: Sapphire King

Super comfy pillow. Fluffs up without any issues and it was the first night in a long time I wasn't allover the bed trying to get comfortable. I appreciate the fact that the material in the pillow can be washed. The prefill was perfect for me so I did not need to remove or add but I like the option to do so. 10/10

Way fluffy, good support

Size: Sapphire Queen

This pillow is way fluffy. It does fit into a standard pillowcase with a little tugging and stuffing. Worth it though, as it’s cool and provides more support than a usual side sleeper pillow. I’m not using the extra stuffing that comes with it as the firmness is fine for me right out of the box.

Great for side sleeper

Size: Sapphire King

I am loving this pillow. I waited a few months to see how I would feel about it, because I definitely did not like solid foam pillows previously. I’m a side sleeper, and my pillows were discontinued from a different bedding company. I tried a few others in the interim and was not happy with the support for my neck. Tried this one and I really love the shredded foam. It supports my neck and my head, it’s comfortable. It is movable if I need support in a certain position. It has extra fill if needed. Super happy with this purchase.
