GoodBed Expert Review
Our Take on Sealy Posturepedic Plus Brenham Firm ("Advanced Support" Hybrid)

Founder of GoodBed, Leading Mattress Expert
- Want a firm mattress
- Are mainly a back sleeper
- Often sit or sleep along the edge of your bed (edge support is very good)
- Are easily disturbed by other movements in the bed (motion isolation is excellent)
- Prefer an above average amount of 'memory feel'
- Would like a mattress that performs very well when used with an adjustable base
- Enjoy sleeping just a bit more 'in' your mattress than 'on' it
- Like just enough bounce that your mattress doesn't feel completely 'dead'
- Weigh 225 lb or more, especially if you sleep on your stomach
- Have a strong tendency to sleep hot (temperature regulation is pretty good, but not the best)
- Tend to have difficulty changing positions during the night (though ease of repositioning is still pretty good)
- Want a natural or organic mattress (though this mattress is still OK in terms of avoiding harmful chemicals)
