We love our new Tuft & Needle King-Size Mattress! It was delivered within 3 days and easy to set up. We lifted it out of the box and placed it on the bed before we cut the plastic. It is so, so comfortable, yet very supportive. After being hit by a truck while on my bicycle, I have had a lot of problems with my back. Now, I don't wake up with a backache anymore. Our very expensive S&F regular mattress started sagging within 6 months and did not help my back at all. This one is perfect!!
I was excited for my mattress and expected it to be great the first time. However, the first couple nights were hard and my lower back hurt a lot on the second night. Its getting slightly better each additional night. I will give the mattress a full 2 weeks to break in before I decide what to do.
