I admit when I was wrong.
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
3/29/26 - I took the pillows and put them in my dryer on steam refresh for the default 10 minute cycle.
OMG - they fluffed up and evened out to be soft and comfortable, no lumps whatsoever. If you like a soft pillow with some support, but not firm support, THIS is what you want. I am truly amazed.
==================================================
Previous review---They arrived in a vacuum seal bag. When you cut the bag and they inflate, they inflate lumpy like. Some areas are thick and some have to fill so, not very good. I am going to try washing them and drying them to see if they fluff up better.
Will post the results in a day or two.

Immediate neck and back pain
Size: Queen - Pack of 2, Style: Medium, Configuration: Pillow
Nice full pillows that holds its shape, BUT was NOT good head and neck support. I noticed an immediate difference. From non existent to growing neck pain in the first night’s use, through the week.

Soft and comfortable

These pillows are incredibly soft and comfortable. They provide great support while still feeling plush and cozy. I’ve been sleeping much better since I started using them.

Perfect Stylish Comfy Queen Size Pillows
Size: Queen - 20"*30" (pack of 2), Color: Grey
These two pillows replaced some very old pillows. They are perfect size for my son’s double bed. They come rolled up and when I removed the plastic they puffed right up to their puffy pillowy size. They are extremely comfortable and my son loves them. They are a down alternative and work perfect for him as he is a stomach sleeper. They have just the right support for a restful nights sleep. They have a nice stylish look 👀. They keep their fluffiness even after sleeping on them overnight. They can be washed in cold water and tumbled dry on low heat. They are the perfect pillows for our family. Extremely happy with our purchase. I highly recommend them. ⭐️⭐️⭐️⭐️⭐️
