These pillows fill out my euro shams well enough, but would prefer the pillows to be a little fuller. I bought some euro sized feather and down pillows from a popular retailer previously and they are fuller. These from overstock are comfortable enough to sleep on, but are not supportive enough for supporting back for sitting up and reading/watching television. For enough support for sitting, you would need at least 2 of these pillows. They do crunch as do most all feather pillows. These pillows satisfy my purpose adequately.
