When my father died back in July, we decided immediately to toss what we called the "FFC". That's Frasier's Father's Chair. Fortunately it was in his room and not a living room. And while it had no plastic cover it was a very worn(out) leather. We got a beautiful bowl, filled it with water from a nearby fall, then sprinkled the chair using a branch of Rosemary. I recited a Native American prayer known in this area. Afterward we put it in the SUV and drove it to the dump. I still felt guilty.
My spouse's parents had what I called a Jetson's Sofa that was still wrapped in plastic. That said, it had been in storage since he and I met. It was gorgeous mid-century ... medium blue ... and I was eager to have them give it to us. Sadly we discovered that critters had found it. The plastic didn't help. They entered from below.
I lost my father in 2010 and my mother in 2015, and I will tell you that the regret you feel for getting rid of things, always pops up. You just can't look back, even if you have virtually unlimited storage options. I put all the "important" things of my father's (that I didn't want in the house yet) in a mini-storage unit. About 5 years ago, I lost the key . . . I still haven't replaced it, it hasn't mattered.
