I think bedding is ridiculously priced. Especially considering I’m happy sleeping on a $200 roll-up memory foam mattress. If I want softer I fold it over itself and voila, double the softness. Then again, I’ve been called a cheapo hermit. I did try the $2k tempurpedic but it sooo wasn’t worth it (to me).
I’ll bet 90% of the overhead of mattress companies is spent on marketing, talking up the benefits of their junk.
