The Nectar Ultra Memory Foam Mattress is Nectar’s premium all-foam option: a tall 15-inch bed with zoned support and cooling materials, priced around $1,799 for a queen. It’s built for sleepers who want a deep memory-foam hug without the midsection collapsing. In our hands-on tests, it stood out for pressure relief and motion isolation, while the slow foam response and softer edges may annoy people who move a lot at night.

Product Overview
| Mattress | Overall Score | Pros | Cons | Ideal For |
|---|---|---|---|---|
| Nectar Ultra Memory Foam Mattress | 4.1/5 | Deep contouring, excellent motion isolation, cool-to-touch cover | Slow response, softer edges, more sink than lift | Side/back combo sleepers, couples, pressure-point sensitive sleepers |
Final Verdict
After several weeks of nightly use, the Ultra delivered that classic memory-foam hug—quiet, pressure-relieving, and cooler than we expected for a thick all-foam mattress. The main trade-off is mobility: the foam rebounds slowly, and the perimeter compresses more when you perch or sit.
Who It’s For
-
Side and back sleepers (including combo sleepers)
-
Couples who notice movement easily
-
Anyone chasing deeper contouring and pressure relief
Who It’s Not For
-
Stomach sleepers who want a firmer, flatter feel
-
Hot sleepers who need the airflow of coils
-
Anyone who dislikes a “stuck-in” memory-foam feel
How We Tested It
We slept on the Nectar Ultra Memory Foam Mattress in a multi-week rotation, switching positions and room conditions to see how the foam stack behaved night after night. We scored support by tracking hip and lumbar alignment, cooling with surface heat checks and sweat notes, and pressure relief through long side-lying sessions. Motion isolation came from partner-movement drills, responsiveness from timed rollovers, edge support from sit-and-lie perimeter tests, and durability from watching for early soft spots and surface wear.
Our Testing Experience
Nectar Ultra Memory Foam Mattress
Our Testing Experience
The first thing you notice is the height. At 15 inches, the Ultra feels substantial when you sit down, and the top foam gives that slow, classic memory-foam “melt” at the shoulders and hips. In our tests as back-and-side combo sleepers, the zoned support helped keep the midsection from dipping too far, which made alignment feel steadier than on many plush foams.
Marcus (6'1", 230 lbs) focused on heat and mobility. He stayed cooler than he expected for a thick all-foam bed, but noted it takes a moment for the foam to rebound when rolling from stomach to back. Jenna and Ethan ran their partner-movement routine; the surface stayed calm, though the edge felt softer when both of them drifted toward the outer third.
What we liked
-
Deep contouring without a hammocky midsection
-
Very low motion transfer for couples
-
Cool-to-touch feel at the surface
Who it is best for
-
Side/back combo sleepers who like plush foam
-
Couples where one partner tosses and turns
-
Sleepers with sensitive pressure points
Where it falls short
-
Fast position changers; the foam responds slowly
-
Frequent edge sitters who rely on the perimeter
-
Stomach sleepers who need more lift

Review Score
| Metric | Score | Remarks |
|---|---|---|
| Support | 4.1/5 | Tri-zone feel helped keep hips and low back from drifting too low. |
| Cooling | 4.6/5 | Surface stayed cooler than typical thick foam, especially early-night. |

| Responsiveness | 3.1/5 | Slow rebound; turning takes more intention than on hybrids. |
| Edge Support | 3.6/5 | Fine for sleeping near the edge, but sitting/perching compresses more. |

| Overall | 4.1/5 | A premium, contour-heavy foam bed with standout quietness and comfort. |
Choosing Guide
If you want a thick, slow-moving memory-foam hug, the Nectar Ultra makes the most sense for side sleepers, back sleepers, and couples who prioritize quiet motion control. In our tests it leaned medium-soft, so heavier sleepers and stomach sleepers should pay attention to whether the hips feel supported over longer stretches. Cooling is best described as “foam-cooling”—a cooler surface and better temperature regulation than many thick foams, but not the open airflow you get from coils. If you want similar pressure relief with easier movement, consider the Amerisleep AS3. If you want sturdier edges and a more buoyant feel, the Saatva Classic is the better direction.
Limitations
The Ultra’s comfort comes with two clear trade-offs: mobility and perimeter stability. The slow-responding foam can make quick turns feel effortful, and stomach sleepers may notice the hips drift lower over time. If you sit on the edge daily, expect more compression—especially if you use the same corner every night. If you want a springier surface, reinforced edges, or a more “on top” feel, this model is a tougher fit.
Alternatives
Why you’d pick the Nectar Ultra
-
You want deep memory-foam contouring with a steadier midsection.
-
You share a bed and care about strong motion isolation.
-
You prefer a tall, plush feel with built-in cooling materials.
Alternatives to consider
-
Amerisleep AS3: less sink-in and easier position changes.
-
GhostBed Luxe: stronger emphasis on cooling for heat-sensitive sleepers.
-
Saatva Classic: a bouncier coil feel and sturdier edges.
Pro Tips
-
Let the mattress fully expand and air out in a ventilated room before judging the feel.
-
Use a breathable protector; thick foam sleeps best when you don’t trap extra heat at the surface.
-
Pair it with a solid, supportive base to keep the zoned support feeling consistent.
-
Rotate the mattress 180° every few months to even out wear in your most-used zones.
-
If you sleep hot, use breathable sheets and keep the room a few degrees cooler than usual.
-
Side sleepers: a slightly higher-loft pillow can help keep the neck aligned as the shoulder sinks.
-
Couples: if you’re between sizes, the extra width can make deep foam contouring feel less crowded.
-
If you sit on the edge daily, vary your spot to reduce repeated perimeter compression.
-
If you’re coming from springs, give yourself a short adjustment window—this foam feel is different.
-
If turning feels effortful, a smoother fitted sheet can make repositioning easier.
FAQs
Does the Nectar Ultra Memory Foam Mattress feel supportive enough for back sleepers?
On my back, the midsection felt steadier than most plush foams, so my lower back didn’t feel like it was floating. If you want a firm, on-top feel—or you’re heavier—you may still prefer a hybrid with more lift.
How warm does it sleep compared with typical memory foam?
The cover starts cool and stayed more temperature-neutral than we expected through the first few hours. Past that, it’s still foam: breathable bedding and a cooler room usually matter more than chasing “ice-cold” claims.
Is it a good choice for couples?
For couples, the movement tests were the highlight—getting in and out barely traveled across the surface. The main caveat is mobility: if both of you toss and turn, the slow rebound can feel a bit sticky.
