Exactly what we were looking for in mattress!
Bed came wrapped in two  heavy plastic bags and rolled up like a burrito.
We cut the outside plastic and let it sit  flat before sliding it onto our bed frame.
Didn’t have any noticeable odor like I read in some reviews.
We previously had a 4” gel  memory foam topper on top of our firm mattress,and this was a similar experience.
I only woke up once during the night,where normally it’s several times.
It took the two of us to carry it into the house.(it weighs about 125 pounds!)
This purchase worked out best for us because we didn’t want the hassle and cost of a separate mattress and box spring.
Great experience and worth every penny!
