When I received my two pillows I was concerned they wouldn't be as fluffy as advertised; they came rolled up and shoved in a small box. However, after some time sitting out they are even fluffier than imagined. Firmness is exactly what I wanted and even after my husband folds them, they bounce back to their previous shape.

Definitely beats sleeping on the floor!

Color: Grey, Size: Twin

I was sleeping on the floor with my dog after she had emergency surgery and this helped me get through those tough couple of weeks. Comfortable and not too heavy. Comes with a bag to store it in and helps make it easier to move around.
