I see one mattress on AliExpress unless you're looking for a very thin European? mattress or pad. $300+ for a Queen.

"Yet you could have gone to AliExpress and bought the same none branded mattress for $100."

You proved the statement to be false. Not to mention, what you have posted are coil mattresses. Companies like Casper and Tuft mark-up quite a bit if AliExpress is "warehouse" pricing, but it's really not outrageous.
