The flagship all-foam Nectar: deepest cooling, deepest cradle
The Nectar Ultra is the top of the all-foam line: fifteen inches, a plush 3-out-of-10, with the brand’s most advanced cooling and its deepest pressure-relief foams. If you have slept on a Tempur-Pedic and loved the slow, body-conforming hug, the Ultra is the closest all-foam feel Nectar builds, and it lands at a friendlier tier. It is the Nectar for the sleeper who wants the full luxury-foam experience: a deep, slow cradle that still works to sleep cool.
What tops the line
Two things set the Ultra above the Luxe. Its cooling is the most advanced Nectar builds, an advanced cover over the comfort foams aimed at the deep-foam sleeper who runs hot. And its pressure-relief foams are the deepest in the line, so the cradle at the shoulders and hips is the most enveloping Nectar offers, fifteen inches tuned so plush never goes formless.
What you notice in the first few minutes
Lie down and the surface gives way slowly. The shoulders and hips press in, the foam takes its time, and within a minute or two you have settled into a cradle rather than landed on it. A plush 3-out-of-10 reads as genuinely soft, the full sink-in-and-sigh feel, but it is not bottomless: under the comfort foams sit a transition layer and a high-density core, so the deep plush has a floor. You are held, not swallowed.
What it is made of, and what is not in it
The Ultra stacks an advanced cooling cover over deep pressure-relief memory foams, a transition layer, and a high-density support core. Every foam is CertiPUR-US certified, tested for content and emissions, and Nectar builds the Ultra 100% fiberglass-free, so there is no glass-fiber fire barrier under the cover. For a deep all-foam bed you sink into nightly, those two facts are worth as much as the feel.
Who it suits, and who it does not
This is a side sleeper’s and a luxury-plush seeker’s bed. On your side, the shoulder and hip drop into the most comfort foam Nectar makes, which keeps the spine in line and the pressure points quiet. Lighter-weight sleepers tend to love a soft, deep bed like this one. It is not for everyone, though. If you sleep mostly on your back or stomach and want a firm, on-top feel, this much plush reads as too soft, and your hips may settle further than you want. If you are a heavier sleeper, you may want the coil support of the Ultra Hybrid under this depth of foam.
Foam or coils?
This is the all-foam Ultra: the deepest, quietest, most enveloping version. The Ultra Hybrid sets the same luxury comfort over wrapped coils for more support, the most airflow in the line, and a firmer edge. If it is more bed than you need, the Luxe is plush and a touch lower; the Premier and Classic are the mediums below, all on the Nectar wall.
Living with it over time
For couples, the all-foam build is the quiet one: the layered foams absorb a partner’s movement before it reaches the other side, so someone turning over late stays on their own side. The high-density core keeps the deep plush honest over the years rather than letting the surface go slack. Plan for the height: at fifteen inches this is a tall mattress, so reach for deep-pocket sheets (fifteen inches or more). It does not need a special foundation; a platform, a slatted base with narrow gaps, a solid foundation, or an adjustable base all work.
Ten minutes beats ten reviews
A flagship is worth feeling against the rest of the line, the only way to know the cooling and the cradle earn the step. The Ultra is on the floor across all five Mattress Overstock showrooms in Kentucky (Lexington on Nicholasville Road, Richmond, Georgetown, London, and Somerset), beside the whole Nectar ladder, no appointment needed. Everyone on the floor is paid the same no matter which bed you choose, so the guidance is honest. Buy it and you get Nectar’s full 365-night home trial; if it is not the one, it exchanges for store credit toward any bed of equal or greater value (no cash refunds, just pay the difference). Select your size to see the live Mattress Overstock price. Delivery, setup, and old-mattress removal are free across the Kentucky service area, and Nectar’s Forever Warranty is honored on every bed bought from an authorized dealer. Lie on it next to the Luxe and the Ultra Hybrid in Lexington this week, and let the difference decide.

Flagship all-foam, layer by layer
The Ultra is the most-built all-foam bed in the line:
- Advanced cooling cover. Nectar’s most aggressive cooling surface, right where your body meets the bed.
- Deep pressure-relief memory foams. The deepest comfort layers in the line, for the most enveloping cradle at the shoulders and hips.
- Transition layer. Bridges the deep plush to the core so the cradle keeps a floor instead of bottoming out.
- High-density support core. Holds the deep plush feel and supports the spine over time.
Fifteen inches and a true plush (3/10). Every foam is CertiPUR-US certified, the Ultra is built 100% fiberglass-free, and it is backed by the 365-night trial and Nectar’s Forever Warranty.
For the luxury-plush sleeper
Side sleepers: the deepest cradle in the all-foam line. The shoulder and hip sink into the most comfort foam Nectar offers, which keeps the spine in line and quiets the pressure points.
Luxury-plush seekers: if you want the full sink-in-and-sigh feel, this is the flagship soft, the closest all-foam bed to a Tempur-Pedic hug.
Hot-sleeping foam lovers: the most advanced cooling in the line, for deep foam without all the trapped heat (a hybrid still breathes more).
Couples: all-foam keeps a partner’s movement on their own side, one of the quietest beds on the floor for two.
Lighter-weight sleepers: soft, deep beds suit lighter bodies especially well, since less weight pairs naturally with a surface that gives.
Back and stomach sleepers, heavier sleepers: probably not your bed. A true 3/10 plush reads too soft for an on-top feel, and at higher body weights you may want the coil support of the Ultra Hybrid under this much foam.

Frequently asked questions
How soft is the Nectar Ultra?
Genuinely plush, about 3 out of 10, with the deepest comfort foams in the line, so it is the most enveloping Nectar.
Ultra or Luxe?
Both are plush (3/10), but the Ultra is taller (15″), has the most advanced cooling, and the deepest comfort foams. The Luxe is plush and a step lower in cooling and height. Feel them together to see if the flagship earns the step.
Is it the coolest all-foam Nectar?
Yes. It carries Nectar’s most advanced cooling. That said, any all-foam bed traps more heat than a hybrid; if you sleep very hot, the Ultra Hybrid is cooler still.
Is it like a Tempur-Pedic?
It is the closest all-foam feel Nectar builds to a Tempur-Pedic: a slow, body-conforming hug, at a friendlier tier. If you liked that deep-foam cradle and want it cooler and plusher, the Ultra is the one to lie on.
What is it made of, and is it fiberglass-free?
An advanced cooling cover over deep pressure-relief memory foams, a transition layer, and a high-density support core. Every foam is CertiPUR-US certified for content and emissions, and Nectar builds the Ultra 100% fiberglass-free, so there is no glass-fiber fire barrier inside.
Foam Ultra or Ultra Hybrid?
The all-foam Ultra is the deepest, quietest hug; the hybrid adds coil support, the most airflow in the line, and a firmer edge. Same luxury comfort on top.
How is it for couples?
Excellent. All-foam construction isolates motion, so you will not feel a partner move.
How tall is it? Will my sheets fit?
Fifteen inches. Use deep-pocket sheets (15″+) so they fit the tall profile.
Do I need a special foundation?
No. Platform, slatted base (~3″ gaps or less), solid foundation, or adjustable base all work.
What is the trial and warranty, and can I see it near me?
