I've never understood the ick factor with bed linens. Sleeping in used linens is a fancy treat at a hotel, but not at home? I just roll my eyes and laugh. More quality bedding at the thrift store for me, then!
I also don't do mattresses, or upholstered furniture, mainly because of the bed bug thing. I do have a thrifted couch in my basement, but we've had it for years -- before the bed bug scare. I inherited by mom's oak canonball couch and chair when she upgraded. A gorgeous, timeless set that at most will need cushion replacements at some point. For now, I can sew my own cushion covers for an easy update, so no need to thrift upholstered items ever again.
