Hi shadowfox606,
You can see some of my comments about how Tuft & Needle and Casper and some of the other “one choice fits all” mattresses compare in post #3 here.
A forum search on “Casper Tuft Needle” (you can just click the link) will also bring up all the forum posts and feedback that mention both of them. Some of them also include some comments from a few forum members here that have tried both of them (see post #2 here).
