Somehow this thing is too hard and too soft at the same time. My back is killing me.

Very happy with my purchase, I was skeptical because I had purchased a memory foam mattress pad before and I just sunk right down into it, so I thought let's try firm although it is firm it does have some give to it I feel it is nice and supporting not too hard may take a little getting used to, with health issues it actually seems to be helping me very happy with my purchase I would recommend 😁

Very pleased

Arrived quickly, easy to follow directions (let it ‘reform’ for 48 hours or so) and very firm. Just what I wanted. My existing mattress is a Scandinavian-type and for a platform bed. It is not very high, so my fitted sheets cover both the mattress and topper in my case, which is extra nice.
