CategoryCriteriaCasper RatingLull RatingWhat Users Say
Customer SatisfactionBased on data collection, this is an overall customer sentiment regarding the X and Y mattresses.74% (The Wave)
72% (The Casper)
69% (The Essential)
71%The Casper has a satisfaction rating that is on par with the average rating for all memory foam models (72.5%).
Durability The average mattress will perform for at least seven years before it needs to be replacedFair (all models)FairWhile durability appears to be good for Casper and Lull models, both brands have been in business for a limited amount of time and the mattresses have not been assessed for long-term performance.
Motion IsolationFoam-based mattresses are designed to minimize motion and isolate it from other areas of the sleep surface, which can cut down on nighttime disruptions.Very Good (all models)Very GoodMotion isolation is a key strength of all three Casper models, as well as the Lull Mattress.
Sex Foam-based mattresses are less responsive by design, and may not be as suitable for sex as innerspring or hybrid models.Fair (The Essential)
Good (The Casper and The Wave)
FairThe Casper and The Wave are bouncier than most foam-based mattresses, but The Essential and the Lull Mattress may not be responsive enough for some couples.
ConformingFoam-based mattresses conform closely to sleeper’s bodies, which can help align the spine, target pressure points, and alleviate back painFair (The Essential)
Very Good (The Casper and The Wave)
GoodThe Essential provides minimal conforming and pressure relief, but The Casper and The Wave conform quite closely and can alleviate aches and pains to a significant extent. The Lull Mattress offers good conforming and pressure relief.
Temperature NeutralityFoam retains more body heat than other materials, and foam mattress owners often ‘sleep hot’ as a result.Good (The Essential)
Very Good (The Casper and The Wave)
FairThe Lull Mattress can be a heat trap, according to owners, but the three Casper models retain minimal body heat and sleep fairly cool as a result.
Off-gassingSome mattresses emit particles when they are unpackaged, accompanied by unpleasant ‘off-gassing’ smells that can last for days.Fair (The Casper and The Essential)
Good (The Wave)
FairOdor potential is a common complaint among those who own The Casper, The Essential, or the Lull Mattress, but The Wave emits very little odor.
Edge SupportBecause of their construction, foam-based mattresses often provide little to no edge support and may sink prematurely in areas of the bed where people tend to sit.Fair (The Casper and The Wave)
Poor (The Essential)
PoorOur owner feedback indicates that The Casper and The Wave offer some edge support, while The Essential and the Lull Mattress provide little to no edge support.
NoiseFoam-based mattresses create little to no noise, due to their lack of springs, coils, and other metal componentsExcellent (all models)ExcellentThe three Casper mattresses and the Lull Mattress are all virtually silent when bearing weight.
Ease of Moving and RotatingAll mattresses are relatively heavy when it comes to moving and rotating, but some are heavier and more unwieldy than others.  Very Good (The Casper and The Essential)
Fair (The Wave)
Very GoodThe Wave is somewhat heavy, but the other two Casper mattresses are fairly light and easy to move. The Lull Mattress is relatively light, as well.
