Like the Sleep Number smart bed, the ComfortNext Lux offers 100 firmness levels, and the one you choose is the “Sleep Number,” or how firm you like to sleep. I usually look hard to support the lumbar and distribute the weight, which has been from 40 to 50. Then, a new concept appeared in the program – my strength was in the middle of the 70s, but going slowly can improve my sleep, which Sleep Number calls “SleepIQ score” and reports in its program. I decided to lower it to 35 degrees.
The SleepIQ score provides a summary of your sleep performance at night, including heart rate, pulse rate, and time spent asleep. This data is compiled into scores that summarize your sleep patterns. The results of this program are always lower than that Apple Watch SE would follow. However, with dogs jumping in and out of bed, sensors track this movement and take it into account. Despite this, my Apple Watch showed a six-day trend of 80s to 90s sleep. Since my body tends to get used to new beds with a revolving door for the mattress to try, this is very rare for me. At first, by testing others smart beds or standard mattress types like memory foam or hybrid, I can sleep better if this is a firm or firm mattress, not soft.
What stood out after two weeks of testing was that, even in the toughest 100-degree conditions, the ComfortNext Lux still felt a bit stiff. I started hard and went soft, but the truth is that the ComfortNext Lux foam layers make any level of comfort you choose. If you want a firm mattress—like one of our favorite products in the industry, the Plank Firm Luxe-ComfortNext Lux doesn’t even remotely play in the same league. This isn’t surprising, as almost all smart beds I’ve tried don’t have the firmness you’d find in coil-based designs.
You’ve Got Your Back
If you suffer from chronic back pain or have severe back problems such as scoliosis, I do not recommend this smart bed for you. My husband is part of this club, and according to him, ComfortNext Lux lasts for several days. After that, he should go back to a firm mattress to get the support his back needs. To achieve this, the ComfortNext Lux lumbar support is not required for regular stomach sleepers or heavy sleepers who need a lift around their sides. Others basic variables they will have lumbar support bars that form from the bottom, which can be beneficial here. Unfortunately, this feature is not available on Sleep Number at this time, and I do not recommend that you connect this smart bed with another type of adjustable base.
If it’s not back pain, you might wonder how ComfortNext Lux works. In short? Side sleepers. As a side sleeper myself, this mattress provides the level of stability that I often crave for stress relief, with just the right amount of depth to allow for bone comfort. You feel relaxed, not in a claustrophobic way. For couples who sit on the side or the back, the popularity of the foam in the ComfortNext Lux also helped to prevent shocks. However, it is very difficult to move between sleeping positions because you are working against a soft surface when rolling.
