Memory Foam Pillows (Ballard)

These are used, or perhaps just stained? Inherited pillows, still functional memory foam. First one is Sleep Innovations brand, standard size. Second says Bamboo on it and is longer than the standard size one. Third is neck support style pillow, two views, zip off cover (that we have not washed). This is an attempt to rehome them before we trash them- no one here likes memory foam and you can’t donate pillows. From a house with cats.
