Even with 2.5" of Sealy's best ComfortSense Premium Memory Foam, the Brenham achieves a firmness that is hard to find. Definitely the firmest of the Posturepedic Hybrid models, if you like a mattress where you only sink in a little bit, this will not dissapoint.

The Brenham is the first mattress in the Hybrid collection to feature the Sealy Response Pro HD Zoned Coil system. Adding a zone of additional coils where you need it most, the center third of the mattress holds up to more weight giving you better back support. The higher coil count overall also adds to better support and more conforming.

Other Sealy mattresses feature the SealyChill cooling technology only in the foam layers packed lower in the mattress. While that does provide some cooling, by having an application of SealyChill directly on the surface of the mattress you will immediately notice the cooling effects as soon as you lie down.

The DuraFlex Edge is a coil based edge support system that provides exceptional support all the way to the edge of the mattress without any of the drawbacks of a foam encasement. The Duraflex Pro Edge featured in the Brenham takes the breathability to the next level by having ventilation pathways to allow for enhanced breathability, designed to keep your mattress sleeping temperature neutral.

All of the foams in the Brenham Firm are gel-based or premium memory foams that provide several benefits. They are more conforming, durable, and of higher quality than regular foams. They're also all Certi-PUR US certified, meaning you can trust that they are free of harmful substances.

The firmness of the Brenham makes it so that you will not sink in much at all. This is great for back or stomach sleepers that like that hearty feeling of support without any give.
