My small city has 20 or so mattress stores I can think of. They’re always empty, having “seasonal sales”, have people working them that follow you around the store, no direct prices but “I’ll go look that up” and “box spring included this week!”... I hated mattress shopping.
The best thing to happen to mattresses, was that someone figured out you can roll them up and ship them direct.
The fallout from that discovery of Purple vs Casper vs Avacado (my pick, love it) vs whatever... don’t care so long as I never need to go into a mattress store again.
