Pressure Test Results

We’ve pressure tested the Optimistic Plush mattress with petite, average, and large body size people on their sides and back sleeping positions to see what kind of support and comfort you can expect. (Learn how we test)

The Sealy Optimistic tested really well for most body sizes and sleeper positions. For most scenarios tested, the Optimistic provided contouring support and lessened the impact of excessive pressure points (those can cause discomfort during sleep and make you move around, interrupting sleep).

When we tested back sleepers, the mattress tests were very positive for all body sizes. The mattress distributes weight across the mattress well, helping lessen pressure points. There was good support in the all-important lower back area.

For side sleepers, there are some higher pressure readings (you can see some red in the charts), but the mattress still scored well overall after taking into account the other important metrics. So for all body sizes and sleeping positions, the mattress earned either ‘Recommended’ or ‘Good’ ratings.

Warranty

The Sealy Conform Essentials Optimistic Plush mattress comes with a 10-year warranty against factory defects.

Conclusion

The Sealy Conform Optimistic Plush mattress is a medium-feeling bed from the Sealy Conform Essential Collection. The neutral-firm feel of the mattress will appeal to most sleepers, regardless of their preferred sleep position or body size.

Even though the mattress doesn't have premium features, it did perform well during pressure testing. It does a good job in terms of how the mattress “sleeps” for both back and side sleepers of all sizes. This means it'll provide good support and comforting pressure relief.

There are no cooling materials like those found in the more expensive Conform Performance and Premium collections. Those features help control excess heat, but if that’s not a concern or you just want to save money on a good mattress, then the Optimistic Plush is a great choice.
