Pillows can become compressed during shipping and storage, which can cause them to lose their fluffiness. Additionally, some pillows are designed to be compressed for shipping to reduce the cost of shipping and storage.
If your pillow isn't fluffed up properly, don't worry, there are a few things you can do to fix it. First, give the pillow a good shake to distribute the filling. Then, try fluffing it by hand or putting it in the dryer on low heat with a couple of clean tennis balls or dryer balls to help redistribute the filling.
