Comfy pillows! Excellent deal
Color: White, Size: Queen(2Pack)
I received these pillows shrink-wrapped flat as a pancake. But I've received other things this way including whole king-sized mattresses and they always puff up to normal size once you pop them out of the plastic wrap.
These pillows puffed up pretty quickly. I did shake them and pound on them a little off and on for about an hour before slipping some pillow cases onto them. Their not super fluffy but not too flat. I like that their soft yet have a little support. My husband really likes his too. We both get a good sleep on these. I'm a side sleeper so it's really comfy for me to have some "squishiness" like these have.
As far as quality goes, these are nicely stitched and the fabric feels soft. The pillows are rather lightweight and I won't know how durable these are until we've used them for a while.

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. ⭐️⭐️⭐️⭐️⭐️
