Memory foam could never
Size: Queen (Mid Loft), Number of Items: 1
Wonderfully firm, yet responsive and lightweight. Like a marshmallow for your head and neck. I'm a side sleeper, but this could be great for anyone needing firm but still very soft and comfortable support. Memory foam has nothing on actual latex.

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
