Advanced comfort to side sleepers and couples…
The brand describes the ComfortNext Lux as possessing “superior”pressure relief, aiming to reduce build-up in key side sleeper pressure points: shoulders, hips and knees.
Its 100 adjustable firmness levels acknowledge that firmness is subjective, with some side sleepers needing firmer comfort than others. Plus, back and stomach sleepers should be pleased that the ComfortNext Lux is built to provide good lumbar support.
As for bed-sharing couples, the good news is that you can select your own firmness settings independent of the other side of the bed. This means that if your partner prefers a firmer bed while you like a softer mattress (or vice versa), you can choose your respective firmness levels and cancel the sleep divorce.
