Brand appeal I suppose. I remember 1/2 the Casper price tag goes to marketing - I just bought a generic Amazon Zinus for 1/2 the price that research suggested came from the same foam factory. Seems like Zinus has gone down in cost in the last few years as one would expect with economy of scale while Casper has gone up one, $250 now from Amazon shipped, 1/4 of Casper. Simultaneously feels like Casper has cut back on marketing. Also Zinus is a 40 year old Korean company that's been doing bedding for for 15 years compared to Casper, a tech company that's been around for 5. It seems like a no brainer decision for anyone doing rudimentary research.
I have a Zinus I paid like $250 at most on it and it's the best mattress I've ever slept on. But, I ordered one for the guest room and it did not fully expand, so I talked with Amazon and they sent me another one. I took the first one apart, it's pretty simple set of I vaguely remember 4 layers of different foam types. Making these mattresses is pretty simple for all the brands, so the profit margin on an expensive name brand is very high. All you need is a good vacuum and decent packaging for the foam types. I have no idea why anyone would pay $1000-$3000 for a mattress.
