Softer than expected
Size: Queen (Mid Loft), Number of Items: 1
Not as firm as I would like. Make sure you want a soft pillow if you choose this one. Seems high quality otherwise

Super comfortable and great neck support
Size: Queen (Mid Loft), Number of Items: 1
This pillow is super comfortable!
It has support for the neck, which is so important so that my neck doesn’t end up creasing and cutting off your air. Great for side, sleepers or people that need a little bit more support. The height is about 5 inches- it appears firm, but it conforms to your neck shape and supports it. Great value for the money! I own four of them and guests finds them comfortable also

Perfect Pillow
Size: Queen (Mid Loft), Number of Items: 1
This is the best pillow I’ve ever had! Supportive yet soft. Never goes flat. I’m a side sleeper and I have neck and shoulder pain and this pillow keeps my head and neck in alignment. I’m buying a set for our camper and our 2nd home so I can sleep comfortably wherever I go. Price point is spot on for the quality of pillow.
