I may, in less experienced earlier years, have bought a needlessly semi-expensive >$1000 mattress. Even then, after sleeping on it for almost 10 years now, it has amortized pretty well. $100 a year isn't really something to worry over much, and saving half of it makes less of a difference than reducing coffee consumption for example. The cost per year still keeps falling. Even a $2000 mattress wouldn't be a giant expense compared to frequent & more expensive discretionary spending that people casually indulge in, such as new flagship smartphones or desktop CPUs/GPUs after 2-3 years, more than a single streaming video service or (God forbid) a car if bike+transit is a viable choice in your area. Nowadays I'd go about mattresses a little different, but in the grand scheme of things? Not even a blip.
