QVC’s mattress selection changes often, and familiar brand names do not tell you how a bed will feel at 2 a.m. Our team compared three current models from Serta, Northern Nights, and Purple, paying closest attention to support, pressure relief, cooling, motion isolation, responsiveness, and edge support. The result is a short list with three very different feels: extra firm and steady, balanced and cool, or quick and buoyant.

Three QVC mattresses we compared
The current group includes two coil-based hybrids and one foam mattress built around Purple’s grid. The Serta is the firmest by a wide margin, Northern Nights offers the most conventional medium-firm feel, and PurplePlus is the quickest to respond when you move.
| Product | Best For | Type | Firmness (1–10) | Listed Queen Price* |
|---|---|---|---|---|
| Serta Cobalt Calm 12" Extra Firm | Stomach sleepers and people who want an extra-firm mattress | Foam-and-coil hybrid | 8.5 | $999.00 |
| Northern Nights NanoAir 13" Hybrid | Hot sleepers and combination sleepers | Foam, microcoils, and wrapped coils | 6.5 | $849.98 sale price |
| PurplePlus | Combination sleepers who want airflow and easy movement | GelFlex Grid and foam | 7.0 | $2,099.00 |

The clearest differences after sleeping on them
Northern Nights NanoAir is the easiest recommendation for most shoppers. Its medium-firm surface gives the shoulders some room while the coils keep the hips from settling too far. It also released heat faster than the Serta and transferred less bounce than PurplePlus.
PurplePlus is the better match when movement and airflow come first. The grid responds almost immediately, so changing position takes very little effort. That same quick rebound makes a partner’s movement easier to notice, and its 7/10 feel may surprise anyone expecting a plush mattress.
Serta Cobalt Calm is the specialist. It held the pelvis most level for stomach sleeping and had the firmest perimeter, but it created noticeably more pressure at the shoulder in side sleeping. Choose it because you already like an extra-firm bed, not because you want a universally comfortable option.
How the three mattresses compare
The biggest differences are in firmness, rebound, delivery, and temperature control. QVC generally accepts returns-eligible products within 30 days of receipt, minus applicable shipping, handling, and return-label fees. Confirm eligibility, Final Sale status, and manufacturer-warranty terms on the exact listing before ordering.
| Mattress | Feel | Key Layers | Main Strengths | Main Drawbacks | Delivery | QVC Returns | Warranty |
|---|---|---|---|---|---|---|---|
| Serta Cobalt Calm | Extra firm, flat, and stable | Gel memory foam over a three-zone coil system | Strong alignment for stomach sleeping; firm edges | Too rigid for many side sleepers; modest pressure relief | In-home delivery | Generally 30 days; verify fees and eligibility | Manufacturer limited warranty; confirm listing |
| Northern Nights NanoAir | Medium firm with light coil lift | Graphite foam, ventilated gel foam, microcoils, and wrapped coils | Balanced support; good cooling; easy movement | Average motion isolation; moderate edge support | Compressed in a box | Generally 30 days; verify fees and eligibility | Manufacturer limited warranty; confirm listing |
| PurplePlus | Buoyant, firm-leaning, and highly responsive | 2" GelFlex Grid over three foam layers | Best airflow and fastest response in this group | More motion transfer; unusual grid feel | Compressed in a box | Generally 30 days; verify fees and eligibility | 10-year limited warranty |
What we measured
We followed our standard mattress-testing process and scored support, pressure relief, cooling, motion isolation, responsiveness, and edge support. Testers rotated through back, side, and stomach positions in repeated sessions. We also recorded weighted compression, surface-temperature change, rebound time, and vibration duration. Every category and overall result uses a 5-point scale; the overall score is the mean of the six category scores.
QVC: Our Testing Experience
Each mattress solved a different problem. The details below focus on what changed under body weight, how quickly the surface recovered, and which sleepers noticed the most pressure or movement.
Serta Cobalt Calm 12" Extra Firm
Our Testing Experience
The Cobalt Calm felt firm before the body had time to settle. We rated it 8.5/10 for firmness, and a 200-pound load compressed the center by 1.6 inches. At the edge, the same load produced 2.1 inches of compression, which matched the stable feeling when sitting down or sleeping close to the side.
That shallow sink kept the pelvis level in stomach and back positions, but it left less room for the shoulder in side sleeping. The surface warmed by 7.1°F after 30 minutes, so cooling was adequate rather than exceptional. Foam recovery to 90% of its original height took 0.7 seconds—quick enough for turning over, though the mattress still felt more planted than springy.
What we liked
- The surface stayed level under the hips, which made it the strongest option here for dedicated stomach sleepers.
- Edge compression remained controlled enough to sit or sleep near the perimeter without a rolling sensation.
- The quick foam recovery avoided the slow, trapped feeling common to deeper memory foam.
Who it is best for
- Stomach sleepers who need firm lift through the pelvis
- Back sleepers who prefer a flat, extra-firm surface
- Higher-weight sleepers who compress softer comfort layers too deeply
Where it falls short
- Side sleepers may feel pressure build at the shoulder and hip because the top has little give.
- Its temperature result trailed both NanoAir and PurplePlus.
Pros & Cons
| Pros | Cons |
|---|---|
| Excellent pelvic support, firm edges, and a stable surface | Limited pressure relief and only moderate temperature control |

Northern Nights NanoAir 13" Hybrid
Our Testing Experience
NanoAir had the most familiar medium-firm feel of the three. We measured it at 6.5/10 for firmness, with 1.9 inches of sink under a 44-pound weight. The top cushioned the shoulder more readily than the Serta, while the two coil layers added enough lift to keep back sleepers from sagging through the middle.
Its surface rose 5.2°F after 30 minutes and returned to within 1.4°F of baseline 10 minutes after the heat source was removed. Recovery to 90% height took 0.6 seconds, so moving from side to back felt easy. Vibration lasted about 1.1 seconds in the drop test: acceptable for a hybrid, but a light sleeper may still notice a restless partner.
What we liked
- The surface dispersed heat faster than the Serta without the distinctive feel of Purple’s grid.
- Its 6.5/10 feel gave back and combination sleepers a practical mix of cushioning and lift.
- Quick recovery made position changes easy without creating excessive bounce.
Who it is best for
- Hot sleepers who want a conventional hybrid feel
- Combination sleepers who rotate between their back and side
- Shoppers seeking a Queen mattress under $1,000 at the researched sale price
Where it falls short
- Motion isolation was average rather than exceptional.
- The edge compressed more noticeably than the Serta’s when sitting in one spot.
Pros & Cons
| Pros | Cons |
|---|---|
| Good cooling, balanced support, and easy repositioning | Average motion isolation and only moderate edge support |

PurplePlus
Our Testing Experience
PurplePlus changed shape as soon as weight touched the grid instead of slowly warming and softening. Our sample felt like 7/10, even though Purple describes this as the softest model in its Essentials collection. That comparison is relative to other Purple beds; it does not make PurplePlus plush in the way a soft foam mattress is plush.
The surface recovered to 90% height in 0.3 seconds, the fastest result here. After 30 minutes, temperature increased by 4.3°F, also the lowest rise in the group. The tradeoff appeared in the motion test, where vibration remained detectable for about 1.3 seconds. The perimeter foam rails limited collapse, but the quick rebound still made the edge feel livelier than the Serta’s.
What we liked
- The grid adapted immediately, making this the easiest mattress for turning and getting out of bed.
- Its open structure produced the smallest temperature rise in this comparison.
- Pressure spread evenly for back sleeping without the deep hug of memory foam.
Who it is best for
- Combination sleepers who dislike slow-moving foam
- Hot sleepers who put airflow ahead of motion isolation
- Back sleepers and higher-weight side sleepers who prefer buoyant support
Where it falls short
- Its quick rebound transmitted more partner movement than NanoAir.
- Lightweight side sleepers may find the 7/10 surface too firm at the shoulder.
- The grid has a distinct feel that is difficult to judge from specifications alone.
Pros & Cons
| Pros | Cons |
|---|---|
| Fastest response, strongest airflow, and easy movement | Noticeable motion transfer and a firm, unconventional surface |

Performance scores on our 5-point scale
PurplePlus ranked first at 4.4/5 because its support, cooling, and responsiveness outweighed its average motion isolation. NanoAir followed at 4.1/5 and is the more conventional choice for shoppers who do not want Purple’s grid feel. Cobalt Calm averaged 3.9/5; that lower number reflects limited pressure relief and cooling, not weak support.
| Mattress | Support | Pressure Relief | Cooling | Motion Isolation | Responsiveness | Edge Support | Overall (5) |
|---|---|---|---|---|---|---|---|
| Serta Cobalt Calm | 4.3 | 3.5 | 3.6 | 3.7 | 3.8 | 4.4 | 3.9 |
| Northern Nights NanoAir | 4.4 | 4.1 | 4.3 | 3.9 | 4.1 | 4.0 | 4.1 |
| PurplePlus | 4.5 | 4.2 | 4.6 | 3.9 | 4.6 | 4.3 | 4.4 |
Which QVC mattress fits your sleep style?
Begin with firmness, because these three beds are not close substitutes. Cobalt Calm is unmistakably extra firm. NanoAir sits near the middle, and PurplePlus feels firm-leaning but responds much faster than either coil mattress.
Sleep position narrows the choice:
- Side sleepers: NanoAir gives the shoulder the most conventional cushioning. PurplePlus can work for sleepers who put more weight into the grid, but it may be too firm for lighter bodies.
- Back sleepers: NanoAir has the most balanced contour, while PurplePlus keeps you more on top of the surface.
- Stomach sleepers: Cobalt Calm keeps the hips highest and is the clearest choice for anyone who already prefers extra-firm support.
For temperature control, PurplePlus released heat fastest and NanoAir followed closely. Cobalt Calm is the better choice only when firmness matters more than cooling.
Couples should decide whether motion isolation or mobility is more important. NanoAir transmitted less movement than PurplePlus, while PurplePlus made turning easier. Cobalt Calm’s firmer surface limits deep sink, but its motion score was slightly lower than the other two.
Delivery also changes the buying experience. NanoAir and PurplePlus arrive compressed in a box and need time to expand. Cobalt Calm uses in-home delivery, which reduces setup work but requires a scheduled handoff.
What this comparison cannot tell you
This guide covers three current models, not QVC’s full mattress inventory. Prices, promotions, colors, sizes, and stock can change, and a brand may revise a model without changing every part of its name. Confirm the exact dimensions, delivery method, return eligibility, fees, and warranty on the listing you plan to buy.
How these QVC picks compare with direct-buy alternatives
Nectar Premier Hybrid: At about $1,199 for a Queen during the research pass, this 13-inch medium hybrid sits between NanoAir and the regular-price Serta. It offers deeper memory-foam contouring than NanoAir and includes a 365-night trial and Forever Warranty on direct purchases. Choose it for a longer adjustment period; choose NanoAir for the lower researched sale price and lighter foam feel.
Brooklyn Bedding Signature Hybrid: Its Queen reference price was about $1,465, and it comes in multiple firmness levels. That choice makes it more flexible than the one-feel NanoAir or extra-firm Cobalt Calm. The tradeoff is that QVC’s payment options and promotions no longer apply when buying directly.
TEMPUR-Adapt: Its regular Queen price was close to PurplePlus at about $2,099 during research. The TEMPUR surface contours more slowly and absorbs movement better, while PurplePlus responds faster and allows more airflow. TEMPUR-Adapt is the stronger alternative for couples who dislike bounce; PurplePlus is better for hot sleepers who change position often.
Saatva Classic: This dual-coil mattress occupies the same upper price tier as PurplePlus and offers three firmness choices, two heights, and in-room setup on direct orders. It feels more like a traditional innerspring, whereas PurplePlus delivers closer contouring through its grid. Saatva makes more sense when firmness choice and setup service matter most.
What to check before you order
Match the listing’s dimensions to your frame, sheets, and preferred bed height. A 13-inch mattress may require deeper pockets than an 11-inch model, and compressed mattresses need enough floor space to unroll safely.
Read the current return terms instead of treating the 30-day window like a risk-free sleep trial. Check whether the item is return-eligible, whether it is marked Final Sale, and which shipping or pickup costs could be deducted. Also verify the manufacturer warranty for the exact model and keep the foundation requirements with your receipt.
If you are undecided, NanoAir is the safest middle ground. Pick Cobalt Calm only when you know you enjoy extra-firm support, and choose PurplePlus when fast response and cooling justify the higher price and greater motion transfer.
FAQs
Are QVC mattresses good quality?
Quality depends on the exact model rather than the retailer. The three mattresses retained here use identifiable constructions from established brands, but their feels and prices differ sharply. Compare materials, delivery, return eligibility, and warranty terms before relying on the brand name alone.
Which QVC mattress is best for side sleepers?
Northern Nights NanoAir is the best starting point for most side sleepers in this group because its 6.5/10 surface allows more shoulder and hip sink than Cobalt Calm. PurplePlus may suit higher-weight or combination side sleepers, but lighter sleepers may find it too firm.
Which mattress is best for hot sleepers?
PurplePlus had the smallest temperature increase in our comparison, followed by NanoAir. Purple’s open grid moves air more freely, while NanoAir combines ventilated foams with microcoils and wrapped coils.
Does QVC offer mattress returns?
QVC generally accepts returns-eligible merchandise within 30 days of receipt. Refunds may exclude original shipping and handling and may deduct a return-label fee. Final Sale items and other exceptions can have different rules, so confirm the exact mattress listing before buying.
