This post is NOT about how long you should keep a pillow. If anything, I can only tell you that you probably shouldn’t keep it as long as I do. It seems to take months to get it just like I want it, with the lumps in all the right places. What I will tell you in this post is, I always write my name and the month/year I purchased my pillow on that annoying tag that says “do not remove under penalty of law.” My husband and I have matching pillow cases and matching pillow protectors. Writing my name helps keep things in line and settle any fights about which pillow is which.
