Setup quirks & things to watch for

Not complaints — practical notes from owners that didn't affect the score.

“I did buy Casper Original, there was another comment here which pointed me to a video of mattress teardown, I didn't see any loose fiberglass in that video. one of the store also opened the outer cover to show what's inside”
— Gada_Electronics on Reddit
“Thanks for your input. Mine was a queen size on a queen size bed frame, didn't have any issues with length or fit.”
— KiwiKuiper on Reddit
“I think the memory foam one would be good for you as it is very soft on top but feels very supportive underneath. I don't feel stuck or sink in too much but just enough. It definitely feels softer than a tempurpedic. I tried those and the foam is too firm for me.”
