Soft and smooth cover
Color: Grey, Size: Body（20"X 54"）
This is a nice pillow cover overall. The fabric feels good and it's comfortable to sleep on, especially compared to a more basic cotton cover. It is maybe a little thinner than I expected, so if you want something thick and heavy this probably isn't that. But for a soft smooth cover that fits and feels decent, I think it's worth it. No major complaints from me after using it.

These are the ones you want
Color: Grey, Size: Body（20"X 54"）
May need to iron them out when wash/dried but my old ones still look new- soft, cooling, smooth, color is still great. Not itchy or cheap feeling. Buying a new set for family.

Very nice pillowcases
Color: Haze Blue, Size: 2 Pack Standard（20"X 26"）
Very pretty pillowcases. I washed them in cold water and dried them on low before using. They came out a little wrinkly but smoothed out on the pillow. The fabric is shiny and rich looking. It's not hot yet, here in Texas, but I am anticipating the coolness of these pillowcases to feel very nice. I appreciate the envelope closure. It gives it a finished look. There was no odd odor. They feel good like they'll last for a long time. I am a satisfied customer.

Body pillow covers
Color: White, Size: Body（20"X 54"）
I ordered the body pillow covers. They fit my pillow perfectly and the fabric is smooth and silky, but I did not find them cooling.

Cooling King-Size Pillows (used on a Queen pillows to tuck the extra in)
Color: Navy Blue, Size: 2 Pack King（20"X 36"）, Color: Navy Blue, Size: 2 Pack King（20"X 36"）
🛏️ Product Review: Cooling King-Size Pillows (used on a Queen bed)
⭐ The Good
• These are king-size pillows, which I actually love on a queen bed because I can tuck the ends into the fabric.
• The fabric feels slick and cool, but you don’t slip off of it.
• They feel cold to the touch right out of the package (which is wild).
• I sleep extremely hot and even run fevers at night due to a medical condition (literally 101–102° sometimes), and these pillows still stay cool where I lay my head.
• I’ve honestly never slept this well in my life.
• For the price, you cannot beat them, and they go on sale often.
• These beat any high-end version I’ve tried.
• If you sleep normal-temp and not lava-hot like me, you’re going to be VERY comfortable with these.
⚠️ The Bad
• The fabric does show crease lines.
• If wrinkles bother you, this might annoy you (doesn’t bother me personally).
🔧 What I’d Change / Tips for Care
• Don’t use fabric softener — it clogs the cooling fabric and ruins how it works.
• Wash with unscented detergent + a little vinegar.
• Dry on low heat only (do NOT dry on high if you want the fabric to keep working long-term).
✅ Final Thoughts
I will literally never not own these again.
If you sleep hot, night-sweat, or just want a pillow that actually stays cool — these are it.
10/10 recommend.
