Our mattress is worn, dips in the middle, hurts my husbands back and I roll into the middle. Got this topper as a temp fix until new mattress can be purchased. It's great! It's soft but not too soft. There was no smell. I was worried it'd hold too much heat since my husband is always hot. But no problem there. No more back problem complaints. thats been the best benefit. I still sometimes roll in the middle but that's because he's heavier than me. Shipped fast in a surprisingly little box. My bed is enjoyable again.
