Please give 48-72 hours to the pillow to fully expand. You can also tab or press the pillow few times to hasten expansion. If your pillow still does not expand, please use the following methods to spring them up:
1.Put Pillows in the Dryer with 2 Tennis Ball:
Start off by placing your pillow in the dryer with 2 tennis balls (preferably wrapped in a cloth or socks separately). The tennis ball will hit the pillow, fluffing up the filling. Tumble dry low for an hour to make sure your pillow become fluffier and softer.
2. Leave the Pillow in the Sun:
By placing pillows in the sun for a few hours on a bright day will evaporate the moisture that builds up over nights of use and the pillows will fluff up over the course of the day. You could also hang the pillows outside on a clothes line, if you have one.
