A couple questions. Why are mattresses now so stinking thick? My wife is about 5'4" and almost needs a stool to get into bed. Why are the foam mattresses so expensive? It seems they have $50 of product, $100 of labor, and $1,500 of profit. Lastly, why would anyone want to buy a mattress on-line? Actually stretching out on one is more important than any on-line article or advert.
