I was honestly skeptical at first to try out a Sleep Number mattress because I had never owned such a high-tech bed before. (Does anyone need all those bells and whistles?!)
But now, after only a few weeks, I can genuinely say the Sleep Number ComfortNext Ultra mattress has improved my sleep enormously. I now fully understand why people become obsessed with these beds.
Here, my honest review of the ComfortNext Ultra, plus why I gave it a whopping 99 out of 100 rating.
This state-of-the-art hybrid mattress is the ultimate in support and comfort. Through the Sleep Number app, the mattress allows you to personalize the level of firmness that works best for you—with a different firmness on each half of the bed for you and a partner. It’s designed to offer relief from pressure while sleeping to help with chronic pains. The ComfortNext Ultra is also made from special cooling materials for increased airflow throughout the night. And perhaps most impressive, the accompanying app provides sleep insights so you can track how much rest you’re actually getting.
The delivery/setup team was fantastic. They were beyond organized, super respectful of the apartment and honestly moved incredibly efficiently considering how involved the setup actually is. What stood out most was how knowledgeable they were when helping walk me through the app and controls.
The only small hiccup I had was getting a couple delivery confirmation calls after everything had already been scheduled, so I was briefly confused about whether something changed. Outside of that, the customer service experience was honestly excellent. The executive office check-ins were such a nice personal touch and made the whole experience feel a lot more thoughtful and elevated than I expected. It never felt like I was just another order number.
I was surprised by how intuitive everything is. The app is clean and simple, and the controls don’t feel overly complicated or gimmicky. It took me a few nights to really understand what settings worked best for me, but I think that’s part of the fun of it. Like any new toy, it takes a little experimenting before you fully figure out your sweet spot.
The under-bed lighting may honestly be one of my favorite features, which I did not expect at all. I leave it on auto, so when I get out of bed in the middle of the night, it softly turns on. And when I get back into bed, it shuts off again...such a small thing but genuinely so useful.
Zero Gravity (a setting that elevates the head and legs to create a “weightless” feeling) has also been a gamechanger for me. I haven’t tried the foot warming feature yet—mostly because it’s currently 80 degrees in NYC and I absolutely do not need additional warmth right now. My partner and I also love being able to have different Sleep Number settings accommodating how each of us likes to sleep.
I wasn’t sure how much of a difference changing firmness settings would make. As I mentioned, it took a few nights of experimenting before I started figuring out what firmness worked best for me, but once I landed somewhere in the 35–40 range, everything started clicking.
The biggest thing for me has been back pain. I have scoliosis and have always been someone who tosses and turns constantly, trying to get comfortable. This is the first mattress I’ve owned where I’ve noticed a real difference waking up in the morning. My back feels noticeably better when I wake up, and I don’t feel like I spent the entire night fighting with my sleeping position.
Zero Gravity has absolutely become my thing. I didn’t think I would care much about the adjustable base features at first, but now I use them every single day. TV mode is also dangerously comfortable because I’ll put something on thinking I’ll stay awake and then suddenly realize I’m half-asleep within minutes. The whole experience just feels very relaxing in a way I wasn’t expecting.
I’ve also been really impressed by the cooling side of everything. The sheets are incredibly soft, but more importantly, they truly feel cool. As someone who has dealt with night sweats, I’ve genuinely noticed a difference since switching over to this setup. Between the mattress, topper, cooling sheets and adjustable settings, the whole sleep environment just feels calmer and more comfortable overall.
Between the mattress and adjustable base, I genuinely feel like I’m climbing into a throne every night. Which tracks because I named the bed “King Keith” in the app. Most importantly though, my 3-pound dog Penny is completely obsessed with it and has made herself very comfortable in full Zero Gravity mode where she can sit up high and monitor the neighborhood. If Penny approves, I feel like that says everything.
