Serta Perfect Sleeper Cobalt Calm Firm Pillow Top

GoodBed Expert Review
Our Take on Serta Perfect Sleeper Cobalt Calm Firm Pillow Top

Founder of GoodBed
Michael Magnuson

Founder of GoodBed, Leading Mattress Expert

Bottom Line - Is the Serta Perfect Sleeper Cobalt Calm Firm Pillow Top the right mattress for you?
Bottom line best icon BEST if you
  • Want a firm mattress
  • Are either a stomach or back sleeper
  • 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
Bottom line not ideal icon NOT IDEAL if you
  • Are a side sleeper (though this mattress can be good for side sleepers who prioritize firm support over extra pressure relief)
  • Don't like a lot of bounce in your mattress
  • May use this mattress on an adjustable base (adjustable base compatibility isn't the best, but is still pretty good)
  • Want a natural or organic mattress (though this mattress is still OK in terms of avoiding harmful chemicals)
Sounds good so far? Get the full details.
