Nectar is a fixed-feel memory foam bed in a box. Sleep Number is an adjustable air bed. Here is how they compare on feel, cooling, motion isolation and price, and who each one actually suits.
These two beds sit at opposite ends of the mattress world. Nectar is a compressed, shipped-in-a-box memory foam mattress built around one fixed feel and an aggressive price. Sleep Number is an air-chamber bed you inflate and deflate with a remote, sold at a premium through the brand's own stores. Shoppers compare them because both promise a solution to the same problem: not knowing what firmness you actually want. They solve it in completely different ways.
Pick Nectar if you want a soft-to-medium memory foam feel at a low price, you sleep alone or with a partner who likes the same firmness, and you would rather spend the savings elsewhere. Pick Sleep Number if you and your partner genuinely disagree about firmness, if your comfort needs shift (pregnancy, recovery, a changing back), or if being able to dial the bed in over time is worth a much higher price and a bed that needs a power outlet. If you are between the two, the honest answer for most people is that a well-chosen fixed-firmness mattress you have actually laid on beats an adjustable one you bought on a guess.
| Feature | Nectar | Sleep Number |
|---|---|---|
| Construction | All-foam: memory foam comfort layers over high-density support foam. Hybrid versions with pocketed coils also exist in the range. | Adjustable air chambers under a foam and fabric comfort layer, with a pump and remote or app control. |
| Feel and firmness range | One fixed feel per model, generally in the medium range with noticeable memory foam sink. | Wide adjustable range, from very soft to very firm, changed at any time. Dual-chamber models set each side separately. |
| Best suited sleeper | Side and back sleepers who like contouring and pressure relief, and value shoppers. | Couples with different firmness preferences, and sleepers whose needs change over time. |
| Motion isolation | Strong. Memory foam absorbs movement well. | Good on dual-chamber models, since each side is its own air chamber, though the shared frame transmits some movement. |
| Cooling | Average for foam. Cooling covers and gel help, but memory foam still traps some heat. | Air chambers move some heat, and higher models add cooling materials at extra cost. |
| Edge support | Modest on all-foam models. Sitting on the edge compresses it. | Varies by model. The perimeter is generally more structured than an all-foam bed. |
| Typical price tier | Entry-level to mid-range. | Mid-range to premium, with higher models well into premium territory. |
| Trial and warranty | Long home trial and long warranty are both marketed heavily. Terms change, so check the current policy. | Home trial and warranty are offered, with different terms for the mattress and the electronic parts. Check before ordering. |
| Where to buy | Online, shipped compressed in a box. | Brand-owned stores and the brand website, with in-home setup. |
Nectar built its name on a simple pitch: a genuine memory foam mattress at a price that undercuts the showroom floor. What it does well is pressure relief. The memory foam layers let hips and shoulders sink in, which is exactly what a lot of side sleepers need to stop waking up with a sore shoulder. Motion isolation is a real strength too. If your partner gets up at 5am, an all-foam bed is one of the quietest surfaces you can sleep on.
Where it falls short is the same place most budget foam beds do. Edge support is modest, so sitting on the side to put shoes on feels less stable than it would on a coil bed. Heat retention matters in Los Angeles, where bedrooms stay warm well past midnight for much of the year. And because it ships compressed, you are committing to a feel you have never laid on.
Sleep Number's core idea is sound and genuinely useful for some households: two people who want different firmness levels can have them in one bed. That is a real problem, and very few mattresses solve it. The adjustability also earns its keep when your body changes. Pregnancy, a back flare-up, or recovery from surgery can flip your firmness preference in a week, and being able to soften or firm the bed that night is a legitimate advantage over any fixed mattress.
The trade-offs are also real. It is a mechanical product with a pump, hoses and a remote, which means it needs power and has parts that can fail years down the line. The comfort layer above the air chamber is what your body actually touches, and on lower models that layer is thin, so the bed can feel more like a firm cushion over air than a plush sleep surface. Price is the other barrier: a setup with the features most shoppers want lands well above what a good fixed-firmness mattress costs.
You need enough give at the shoulder and hip to keep your spine straight. Nectar's memory foam does that naturally at a low price. Sleep Number can do it too, but only if you keep the chamber soft enough, and a soft air chamber under a thin comfort layer can leave your midsection less supported. Side sleepers usually get a more predictable result from a well-chosen foam or hybrid bed.
Neither is the obvious winner. Memory foam holds heat, and Sleep Number's cooling comes mostly from upper models that cost more. In a warm climate, look harder at latex or a hybrid with pocketed coils, where air actually moves through the mattress. You can compare options in our hybrid mattresses collection.
This is the one case where Sleep Number has a clear structural advantage. If one of you wants plush and the other wants firm, a dual-chamber air bed solves that in a way a single-feel mattress cannot. The alternative worth knowing about is a split adjustable setup: two separate mattresses on a split base, each chosen for its own sleeper. That gets you independent firmness and independent head and foot positioning. Browse adjustable beds to see how that works.
Support matters more than softness. Most people with lower back pain do best in the medium-firm range, which both beds can reach. The practical difference is that with Sleep Number you have to find that setting yourself, and with a fixed mattress a salesperson can put you on the right one in ten minutes. Read our guide on choosing a mattress for an adjustable bed if you want the positioning benefit without the air chambers.
Nectar wins outright. There is no version of Sleep Number that competes on price with an entry-level bed-in-a-box, and pretending otherwise would be dishonest. The question is whether the cheaper bed is the right bed for your body, which is a different question from whether it is a good deal.
LA Mattress Store does not stock Nectar or Sleep Number, so treat the comparison above as neutral advice rather than a sales pitch. What we can offer is the chance to lie on comparable beds before you commit, which is the part online-only shopping cannot replicate.
If Nectar's appeal is the bed-in-a-box price and feel, we carry three online-native brands you can actually test in person: Helix, Brooklyn Bedding and Birch. Helix builds hybrids across a range of firmness levels, Brooklyn Bedding makes its own mattresses in-house at competitive prices, and Birch is the natural latex and wool option for anyone who sleeps hot. All three ship in a box if you want them to, and all three are on our showroom floors if you would rather find out first.
If deep contouring is what draws you in, Tempur-Pedic is the benchmark for that feel, and Stearns & Foster covers the premium innerspring and pillow-top side. If it is adjustability you want, pair either with a base from our adjustable beds collection. A split king setup gives each sleeper independent head and foot positioning and their own mattress firmness, which is arguably cleaner than one bed with two air chambers. Every mattress we sell comes with our free 120-night comfort guarantee; details are on our Love Your Bed guarantee page, and same-day delivery covers most of Los Angeles.
An air chamber sits inside the mattress under a foam and fabric comfort layer. A small electric pump inflates or deflates that chamber, and you control it with a remote or an app. Firmer means more air, softer means less. Dual-chamber models have one chamber per side, so two sleepers can set different firmness levels in the same bed.
They are worth it in specific situations: a couple who genuinely disagree about firmness, or a sleeper whose comfort needs change often. If you sleep alone and know what firmness you like, you are paying a large premium for a feature you will not use, and that money buys a very good fixed-firmness mattress instead.
The most frequently reported issues are mechanical rather than comfort-related: pumps, hoses and remotes are components that can fail over the years, and the bed needs a power outlet to work. Owners also mention a firm ridge where the two chambers meet on dual-sided models, and that the thin comfort layer on entry models can feel less plush than expected.
The air chambers themselves tend to outlast the comfort layer above them, which is the part that compresses with use. Most mattresses of any type are ready for replacement somewhere in the eight to ten year range, and an air bed follows the same rough curve, with the added variable that electronic parts may need service sooner. See our guide on how long mattresses last for what to watch for.
Both of these beds ask you to make a decision without lying down first, one by shipping in a box and the other by selling only through its own stores. There is a simpler path. Take our sleep quiz to narrow the field in two minutes, then come test the shortlist at any of our five Los Angeles showrooms. Ten minutes on the right mattress tells you more than a month of reading reviews.
