I'd worry less about a product like Casper's than a lot of other products that you expect will need repair/supplies/etc. at some point. Sure it's possible that some gross defect will be discovered in Casper mattresses in a couple years. But it's not like there isn't lots of other furniture that turns out to not be well made. And good luck getting refunds on that after 2 or 3 years in many/most cases.
