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. ⭐️⭐️⭐️⭐️⭐️

Good Pillows to Show Off Decorative Pillow Shams
Size: Queen - 20"*30" (pack of 2), Color: Grey
Although we have queen-sized beds, we typically use standard-sized pillows. One of the quilt sets I got this Christmas time came with queen sized pillow shams, and the standard pillows just didn't fill them properly. I could have sewn flanges on either side of the shams, but I decided to order these pillows instead. The are almost wide enough to fully fill those shams that started all this additional purchasing. (I also ended up ordering pillow protectors for the queen sized pillows.)
The pillows are fluffy and substantial for now. My husband manages to flatten out pillows almost no matter how they start our. For now, so far so good. They re a medium-weight and fullness, I would say. They do a good job of showing off the pillow sham design, so that's a plus. I'm not planning for us to sleep on them, but they are added back support while watching TV. They are primarily for decorative purposes when the bed is made with the quilt and shams. They were a reasonable value for the intended purpose.
