I bought a bed from the Target-backed 'Warby Parker of mattresses' and I'll never buy one in stores again

Casper, the mattress startup behind the pricey, foldable beds that ship in a box the size of a mini-fridge, just raised $170 million in a round led by Target.

Founded in 2013, the "Warby Parker of mattresses" sells memory-foam mattresses online, delivers them to customers' doors, and offers a 100-night trial with free return pick-up. The company, which started selling at Target earlier this week, is valued at approximately $750 million and is planning an IPO, The New York Times reported.

In 2015, I bought a Casper mattress after moving cross-country. Two years later, I'm convinced I will never buy a mattress in stores again (even if it is available at Target). Here's what the buying experience was like.
