Even with 2.5" of Sealy's best ComfortSense Premium Memory Foam, the Brenham acheives 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. Taking the Pro HD system and packing additional coils in the center third where you need it most not only provides additional support in that area, by having more coils overall, this coil system is able to follow every curve of your body more than lower coil count systems.

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.

The only foams you will find in the Sealy Hybrid collection, including the Brenham, are gel based or premium memory foams. These foams provide more pressure point relief, better durability over time, and overall a higher quality product. Also not to be missed is the fact that the foams have all been Certi-PUR US certified, acheiving one of the most recognized certifications in the bedding industry to ward against heavy metals and toxins.

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.
