Have referred several friends and family and they are also very happy with their purchases. Loved my first purchase and just opened my second purchase last weekend.
I've had my mattress for only several weeks. And yet the foam is already starting to sag. I do not think the foam will endure for the 10 years that Tuft&Needle says it will. I do not like sagging, it hurts my back.
I really love this bed, best bed I have ever owned. It sleeps a little warmer (still cooler than other beds) than I was hoping and the mattress protector changes the feel slightly.
