Heloise (as in Hints from) says: “Some sleep experts suggest replacing a pillow every few years, but it’s really up to you. Here’s how to tell if your pillow is doing its job: Is the foam or batting inside the form lumpy or bumpy? Does your feather pillow have to be punched or fluffed up for support? If you fold the pillow in half, does it stay folded? If you answered yes to any of these, it’s time for a nice, new pillow. I give our old pillows to Cabernet, my miniature schnauzer, for her bed—the ultimate in recycling! ” With my old ones, if they are in reasonably good condition, I keep them for company. Or if you have a vacation cabin, perhaps there where extra company is common. We also use them for propping up books in bed. I sleep on one, but have several on each side of the bed.
