The softest mattress offered that we tested is the Sealy Posturepedic Plus Hybrid (4 out of 10). We recommend this for side sleepers of all weights, though lightweight stomach and back sleepers may also find it comfortable. We do not recommend this firmness for back and stomach sleepers above 150 lbs.
On the other side, the Sealy Posturepedic Carver is the firmest option offered by Sealy (9 out of 10). Due to the incredibly firm feel, stomach and back sleepers may find this comfortable, if you find lying on the floor with only a thick blanket between you and the floor comfortable. We do not recommend this firmness for side sleepers.

All mattresses offer a firmness between the 4-9 range. The models within the 5-6 range (medium to medium-firm) will generally be a good fit for all sleeping positions and body weights up to 300 lbs.
For the best Sealy performance at this firmness level, I would recommend the Sealy Posturepedic Plus Prosser Hills or the Sealy Posturepedic Pro Lincoln Heights.
