As someone who remembers what mattresses used to cost before you could buy memory foam mattresses that shipped in a small box from China, $2000 doesn't seem that bad. My wife paid $1500 for some POS Serta mattress and box spring fron some perpetually "going out of business" mattress store when we first got together in the mid 2000s. Without checking an inflation calculator, I imagine that was the equivalent to $4k today for a lumpy mattress with springs that poked your back.
