No way I’m paying $50 for a pillow-not even if it makes coffee and functions as an alarm clock...
One of my neighbors ordered one from that website-got a twofer for maybe $20 more, said it was okay, but not worth that much money-after some weeks, one of them began to come loose along a seam. She noticed and was about to get a needle and thread to repair it-but she checked out what was inside first-it was just regular foam, cut in a certain shape. She sewed it up, and said when they wear out, she knows she can just buy a cheaper pillow with the same foam, but uncut-take out the foam, cut it into pieces in that shape and put it back into the pillowcase and get the same effect for much less...
A cheaper pillow will not have the same foam in it.
There are literally thousands of different kinds of “foam rubber”.
