I chose 5 because, I think it is too soon to tell I have only been sleeping on the mattress/ and protector a little over a week. I will say with the protector over the mattress the sheet sets fit very snug, so that if a person were to add a Tuft & needle topper it would be impossible to fit the sheets over it.
I love my Tuft and Needle mattress but the pillows are too flat and my neck has hurt ever since I started sleeping on it so I've gone back to my old pillow.
I haven’t fully adjusted to the mattress yet but I love my mint bed. Its super comfy, there is little moition transfer, the edge support is great also. I love the feeling of the mattress. It is different from other memory foam beds that I’ve laid on. You don’t feel like you sunk into a hard support layer, like soft foam was put on top of rock hard foam. You feel evenly distributed and the bed is firm but squishy. I use mine with a foundation frame that has drawers underneath.
