Nectar Ultra Memory Foam Mattress

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.
