If you want a mattress that keeps one consistent feel, choose Nectar; if you want to change firmness after setup, choose Sleep Number. For couples with different preferences, Sleep Number’s adjustable-air approach is the more flexible idea. For a simpler all-foam bed and a year-long home trial, Nectar Classic is the easier starting point. My overall advice: decide whether you value a fixed foam feel or adjustable comfort more, then compare the exact size and current terms before you pay.
This review is part of our guide to the best innerspring mattresses, where the strongest models are compared side by side.
Our pick
Saatva Classic — a third option if you would rather have an innerspring mattress with a chosen firmness than foam or adjustable air.
- 365-night home trial on mattresses
- Free in-room delivery and setup
- Free removal of an old mattress
- Three comfort choices: Plush Soft, Luxury Firm and Firm
What is the real difference between Nectar and Sleep Number?
Nectar and Sleep Number represent two different decisions, not two versions of the same mattress. Nectar Classic is an all-foam mattress with a set feel; Sleep Number is known for adjustable air support that lets you alter firmness. Choose based on whether you want a feel selected at purchase or the ability to fine-tune it later.
That distinction matters more than a brand slogan. A foam mattress gives you one surface to evaluate: the comfort layers and support are built into the bed. An adjustable-air mattress adds controls and a comfort setting to think about. That can be useful when you genuinely want to change the feel, but it also means learning the system and checking what the exact current model includes.
Nectar’s official materials describe the Classic as a 12-inch memory-foam mattress and promote a 365-night home trial and Forever Warranty. Those are useful starting points, not a substitute for reading the terms for your exact purchase. Sleep Number has changed its model lineup over time, so do not assume an older review of a C2, i8 or i10 describes the bed currently offered. Confirm the name, configuration and warranty shown at checkout.
Quick verdict: Nectar is the simpler choice if you already like foam and do not need adjustable firmness. Sleep Number is the more adaptable concept if you expect to adjust firmness or need two sides to suit different sleepers. Neither should be chosen by brand reputation alone.
How do Nectar and Sleep Number compare side by side?
The short answer: Nectar emphasizes a conventional foam mattress and a long trial, while Sleep Number emphasizes adjustability. Compare the precise model currently offered—not a brand-wide promise or a comparison article about an older generation. If a price or policy is not clear for the exact model, get the current written terms before ordering.
| What to compare | Nectar Classic | Sleep Number |
|---|---|---|
| Mattress idea | All-foam, fixed feel; 12-inch profile in Nectar’s product information. | Adjustable-air sleep system; identify the current model and its included components. |
| Firmness after setup | Not a dial-adjustable air bed; choose the comfort you want when buying. | Designed around adjustable firmness; confirm how adjustment works on the model you select. |
| Trial | Nectar advertises a 365-night home trial. Review current eligibility and return instructions. | Check the current model’s trial length, eligibility, pickup or return charges, and exclusions directly before purchase. |
| Warranty | Nectar advertises a Forever Warranty; coverage and transportation terms are in the written policy. | Read the warranty for the exact current model and check what is covered, for how long, and who pays any service or transport charges. |
| Queen price | Varies with model and live offer; compare the Classic, not a Premier or bundle. | Varies by current model and configuration; compare the same size and included items. |
| Best match | People who want an all-foam mattress and a set feel. | People who value the option to change firmness or personalize each side, if the chosen model supports it. |
Do not compare a bare mattress price with a configured Sleep Number package. Put the same size in each cart, check whether a base or other component is included, and compare the amount due after the current promotion. Nectar’s product line also includes models beyond Classic; a Nectar Premier quote is not the Nectar Classic price.

Who should buy Nectar?
Choose Nectar Classic if you want a familiar all-foam feel and do not need to change firmness with a control. Its advertised 365-night home trial gives you time to evaluate the mattress, but read the return rules; the trial length alone does not establish that every return is free or unconditional.
This is also the cleaner option if you are buying for one sleeper and do not expect your comfort preference to shift. Start with your normal position and preferred feel, then make sure the exact Nectar model is the Classic. Nectar’s range includes other models, and their names, heights and prices differ. A comparison built around “Nectar” generally may not answer whether Classic is right for you.
Think twice if you already know you need to adjust each night, if two people want distinctly different settings, or if your decision depends on a very specific response from the mattress. Foam cannot be adjusted like an air chamber after the purchase. If you are unsure about returns, read the policy’s eligibility requirements and transportation language before relying on the trial.
Nectar is the practical pick when you want foam without a control system. It is not automatically the better bargain: compare the same size and model, and do not use a temporary promotion or a more expensive Nectar model to represent the whole brand.
Who should buy Sleep Number?
Consider Sleep Number if adjustable firmness solves a real problem for you. It can suit someone who wants to change a setting or give partners more control over their sides. Confirm the exact current model supports the adjustment you want, and check what comes with your selected size and configuration.
Sleep Number deserves a closer look if you have tried fixed-feel beds and found yourself wishing you could make them firmer or softer. Its adjustable-air concept addresses that specific preference. The trade-off is extra complexity: understand how the controls work, what parts are included, what happens if a component needs service, and how the current warranty handles it. Those details can vary by model and should be checked in the current product documents.
Do not buy it solely because an old article lists an attractive price or a particular model. Sleep Number has refreshed its range; older C-series and i-series comparisons may describe discontinued or different beds. Match the model name on the product page to the model in the warranty, trial and order summary. If the current trial or return costs are not obvious, ask the seller to confirm in writing before checkout.
Sleep Number is the more flexible direction for a buyer who will use adjustability. If you would set it once and never change it, a simpler fixed-feel mattress may be easier to compare and own.
Which one works better for couples?
For couples, the deciding question is whether each person wants a different feel. Nectar gives both sleepers the same overall foam surface; Sleep Number’s adjustable-air approach may offer more individual firmness control. Confirm the exact model, size and configuration before assuming both sides can be set separately.
Write down what each partner actually needs: a softer or firmer setting, a quiet sleep surface, less motion transfer, or a different mattress height. Only firmness adjustment is a direct reason to favor the adjustable-air category. Claims about motion, temperature or pain should not be inferred from a product category; look for evidence tied to the precise model and do not treat a brand promise as a guaranteed result for your body.
- Pick Nectar if both sleepers can agree on one foam feel.
- Investigate Sleep Number if separate firmness control is central to the decision.
- For split sizes or bases, confirm dimensions and included parts in the exact order configuration.
One more practical step: test whether both partners can operate the controls and understand the settings. Adjustability only helps if you will use it. If one sleeper prefers a simple bed and the other wants fine tuning, compare the added system cost and warranty details against the actual value of that control.
What should you know about price, trial and warranty?
Compare total prices only after matching the same size, current model and included components. Nectar offers change, and Sleep Number’s total depends on the bed and setup selected. Check what is in each cart, then review delivery, setup, base and return terms before deciding which costs less.
Nectar advertises a 365-night home trial and a Forever Warranty. The company’s written warranty policy describes different handling during the first ten years and after that, including possible transportation costs; read the current document rather than assuming “Forever” means every repair or replacement is free forever. Sleep Number’s trial and warranty must be checked for the current model. A policy from an older model or a third-party summary may not apply to today’s purchase.
Separate the word “trial” from the return process. Before ordering either bed, find out the last eligible return date, whether a minimum break-in period applies, whether a pickup or restocking charge can apply, what conditions must be met, and whether the policy differs for sale or clearance products. Ask which written policy governs if the checkout summary and help page appear to conflict.

If Sleep Number’s adjustable-air approach is the deciding factor, our Saatva Solaire vs Sleep Number comparison looks at another adjustable option. These are related comparisons, not substitutes for checking each live product and policy page.
Is Saatva worth considering instead?
Saatva Classic is a third option: an innerspring mattress with three comfort levels to choose from. Saatva lists free in-room delivery and setup, old-mattress removal, a 365-night mattress trial and a lifetime warranty. Its trial policy lists a $99 processing fee for mattress pickup on a return.
The official Saatva Classic page lists Plush Soft, Luxury Firm and Firm, with two heights. That gives you a choice at purchase; it does not make the bed an adjustable-air mattress. If your main requirement is changing firmness after setup, Sleep Number remains the more relevant category. If you want an innerspring with a chosen comfort level and want delivery and old-bed removal handled, Saatva is worth checking.
Be precise when comparing the terms: Saatva’s lifetime warranty is not a trial, and a 365-night trial is not a warranty. The pickup fee applies to the return process; do not confuse it with delivery or warranty charges. Current promotional prices can change, so open the product page with your size and height selected before deciding.
What is the World Sleep Almanac score?
World Sleep Almanac score: 8.0/10 for this matchup’s decision clarity. This is an editorial comparison score, not a lab result or a personal sleep test. It weights four buyer questions equally: fixed-feel simplicity, ability to adjust firmness, potential usefulness for partners with different preferences, and how clearly trial and warranty terms can be compared before purchase.
- Fixed-feel simplicity: 8/10. Nectar gives buyers a clear all-foam option; Sleep Number’s system is more involved by design.
- Adjustability: 9/10. Sleep Number’s adjustable-air approach is the clear fit when changing firmness is the priority; Nectar Classic is the fixed-feel choice.
- Couple flexibility: 8/10. Separate preferences may favor an adjustable system, subject to the exact model and configuration.
- Buying-term clarity: 7/10. Nectar publishes a long trial and named warranty, but return and transport details still matter. Sleep Number terms need checking for the exact current model.
The score rewards different needs rather than declaring a universal winner. If you want the least complicated foam purchase, Nectar may be your better fit. If you will use firmness controls, Sleep Number may earn the closer look. Neither score predicts comfort, durability or health outcomes for an individual sleeper.
My verdict: buy Nectar if you want a familiar foam mattress and one chosen feel; buy Sleep Number if adjustable firmness is a feature you expect to use. If neither category fits, look at Saatva Classic for three firmness choices, innerspring construction and home delivery with old-mattress removal.
Choose the feel you can live with—not the headline alone. Check the current Saatva Classic price for your exact size and height, and read the mattress trial terms before ordering.

Frequently asked questions
Is Nectar or Sleep Number better?
Nectar is the simpler match for a fixed all-foam feel and a 365-night advertised trial. Sleep Number is more relevant if you want adjustable firmness. “Better” depends on which of those benefits you will actually use and on the exact model’s current terms.
Does Nectar let you adjust firmness?
Nectar Classic is an all-foam mattress with a set feel, not an adjustable-air bed. Choose the comfort level that suits you before purchase; do not expect to change its firmness through a control system after setup.
Is Sleep Number still selling the C2 or i8?
Model lineups change, and older comparisons may cover beds that are no longer current. Check Sleep Number’s live product list and make sure the exact model name matches the product, trial and warranty documents in your order.
Does Nectar’s 365-night trial mean returns are free?
The advertised trial length is not by itself a complete return policy. Read Nectar’s current terms for eligibility, return steps, exclusions and possible transportation charges before ordering.
Which mattress is better for different firmness preferences?
Sleep Number’s adjustable-air approach is the closer fit when separate firmness settings matter. Confirm the exact model and size support the configuration you want. Nectar Classic offers a single selected feel rather than separate adjustable controls.
What is the main reason to choose Saatva Classic instead?
Saatva Classic offers three selectable comfort levels, free in-room delivery and setup, free old-mattress removal and a 365-night mattress trial. The current trial policy lists a $99 processing fee for mattress pickup on a return; check the full policy before purchase.
