Or go to IKEA and get a Sultan mattress for $250 any day or $110 when on sale. Oh and they ship, too.

IKEA’s shipping is not cheap though.

Yeah, because Casper mattresses are a solid block of foam. Way cheaper than spring mattresses, all you need is to source foam sheets, cut them, and roll them for shipment. No springs, no fabric, no filler, no construction.

Have you ever seen a Casper mattress?? Everything you say is provably false. Casper mattresses have a few layers of different types of foam, all packaged together in a nice fabric outer layer. If you've ever seen one, they are clearly a non-trivial construction.

It's most definitely not as simple as "cut them, and roll them for shipment."

So you glue the layers and wrap it in a sheet, big deal. Still way less labor and materials than wiring together 300-500 springs and encasing them with layers of pillow filler.

Huh. I got a mattress last year, went to a regular furniture store, got a regular spring mattress, paid under $300. No going out of business sale, no haggling, and I delivered it myself with a rental truck for less than I would have paid to get it in a week.
