Searched everywhere for comfortable pillows, finally found this set. Perfect density and firmness, very comfortable. Downside is that they were covered in some type of white powder which dispersed as I was fluffing them up. Fiberglass, maybe? I recommend customers fluff and air them outside before use, and wear a mask. Pillows had an industrial smell, which dissipated after 20 minutes in the fresh air.

Great pillows

Color: Black(4pack), Size: Standard

These are absolutely great and them being cooling pillows is a big plus for someone who has hot flashes at night. They are very comfortable and they are great support for any position sleeper. These pillows are durable and the material comfortable and soft.

They are using different/cheaper shredded foam then they were 1 year ago

Color: Memory Pillow, Size: Standard, Color: Memory Pillow, Size: Standard

The shredded foam used last year was really nice and soft and even firm to a point where your head is supported perfectly while you sleep. now the 2 extra pillows I received this weekend have completely different shredded foam which seems to be cheaper. Also when you unzip the pillow cover and get to the part where you can unzip the other cover where the foam is no longer is there. so they are using cheaper shredded foam and a cheaper cover to where the foam is and you can no longer unzip the second cover to see the foam. but I can easily tell that they are using different and cheaper foam which isn't true memory foam. their new blend is too fluffy and the pillows are floppy and too soft. the old ones i bought 1 year ago are heavy pillows that are true memory foam which your head molds into perfectly and are amazing. these new ones they are making aren't worth it. In one picture you can see the cover with different colored cheap foam and the other picture with the green and white thick premium quality shredded memory foam. The other pictures show how the old ones are thick and firm and moldable for you head and the other 2 are floppy because they use cheaper shredded foam. They need to use the shredded foam they used last year! it was really good! Now they are not true memory foam pillows anymore due to changing from premium shredded foam to cheap shredded foam.
