Hi m12w,
Thanks for the heads up … I appreciate it 
It would certainly be of interest for those that have an eligible AMEX card and that are interested in purchasing a Tuft & Needle mattress.
@ Hwang and theglo22,
All you need to do is call or email Tuft & Needle after a purchase to let them know you are a member of the forum here and they will credit the discount to the card that you used for the purchase within a few days.
They are one of the new “breed” of what I call “simplified choice” mattresses. You can read more about simplified choice online mattresses in general in post #1 here and about Tuft & Needle and some of the other simplified choice mattresses in post #2 here in the same topic.
