Worth it!

Size: Queen(Pack of 2)

These pillows are amazing and very soft and comfortable. They came nicely packaged and I let them sit out for just a few hours before using them and that was plenty of time! They come with the cooling cover and fit a standard queen sized pillowcase. The material expands well and does not have any weird smells. 10/10 well worth the price.
