These pillows are truly terrible. They came feeling like stones, squished into a tiny box. They wouldn't unroll and they aren't filled with memory foam, but rather a chunky, sticky, flaky substance that forms into big rocks and needs to be broken up. If you hit someone with this pillow, it could cause a concussion-- they are that hard. I wasn't even planning to sleep on them-- I bought them as covers for the arms of a futon. No good at all. Don't buy them at any price!
