Serta Perfect Sleeper Cobalt Calm Plush
GoodBed Expert Review
Our Take on Serta Perfect Sleeper Cobalt Calm Plush
Founder of GoodBed, Leading Mattress Expert
BEST if you
- Want a mattress with a medium amount of softness
- Are either a back or stomach sleeper (though this mattress can also be good for side sleepers who prioritize firm support over extra pressure relief)
- Regularly sit or sleep along the edge of your bed (edge support is excellent)
- Prefer a slightly below average amount of 'memory feel'
- Enjoy a happy medium between sleeping 'on' your mattress versus 'in' it
NOT IDEAL if you
- Don't like much bounce in your mattress
- Want a natural or organic mattress (though this mattress is still OK in terms of avoiding harmful chemicals)

Yes, the Serta Perfect Sleeper Cobalt Calm Plush 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 Cobalt Calm Plush to have good adjustable base compatibility.
