GoodBed Expert Review
Our Take on Stearns & Foster Lux Hybrid Firm

Founder of GoodBed, Leading Mattress Expert
- Want a medium-soft mattress (i.e., just a little softer than average)
- Are mainly a side sleeper
- Can sometimes be disturbed by other movements in the bed (motion isolation is very good)
- Enjoy being hugged or cradled by your mattress
- Prefer an above average amount of 'memory feel'
- Would like a mattress that performs very well when used with an adjustable base
- Like just enough bounce that your mattress doesn't feel completely 'dead'
- Are a stomach sleeper, especially if you weigh more than 250 lb
- Have a strong tendency to sleep hot (temperature regulation is OK, but not the best)
- Regularly sit or sleep along the edge of your bed (edge support is 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

Yes, the Stearns & Foster Lux Hybrid Firm mattress is adjustable base compatible. This means it is designed to be used on an adjustable base without incurring damage or voiding the warranty. In our review of this mattress, we tested it on an adjustable base to look for any adverse effects as the head and foot are elevated, and to see how well it conforms to the contours of the base both with and without the weight of a sleeper. Overall, we found the Lux Hybrid Firm to have very good adjustable base compatibility.
