The pillows fluffed up nicely - up to twice the size of the box they came in. We used them right away and noticed that they resumed their shape after a few minutes of non-use. They are an exceptional quality for the value. I think that they are a bit too soft for me though, but my husband loves the softness. I will just have to get a firmer pillow for me. My kids love it too. My older daughter now wants these pillows. I would definitely recommend them.
