The stiffness is mid-to-hard-ish, which I feel very comfortable with. Memory foam feels a lot different from my previous spring mattress but it's in a good way. It deforms to fit the shape of my body and provides nice support.
My lumbar has been feeling stiff for months until putting this topper on. I wouldn't believe this kind of product can help at all! It provides enough supports for my entire back and easy to put onto the mattress.
This is best experience for this price mattress, very comfortable and shaped hard. Not too hard or too soft, my husband said his back not pain after 2 days sleep later. And I recommend my friends to buy it too.
I have this one bought because my old meters is too soft. I have a new born baby this year and I have bad pain on my back. This mattress is firm enough for me, and it’s comfortable and help me release my back pain.
Very satisfied with this mattress. First of all, it has two sides, the gray side is soft, the blue side is hard, I prefer the blue side. It has straps at all four corners to keep it firmly attached to the mattress underneath. I slept better after using it.
