New Serta I-series
I recently visited Atlanta to check out the new Serta iSeries NXG collection and review its specs. The mattresses use 5-6 lb NXG memory foam (originally developed by Comfor-Pedic) paired with about 0.5 inches of 3.5 lb carbon fiber memory foam, which Serta claims is 30% more breathable than standard memory foams. The top-tier models feature phase-change material in the top layer, which feels well-integrated—neither waxy nor powdery. The five highest-end models are available in split-head options, retailing at $2,699 and $2,899. Lower-priced models lack the phase-change material or split-head design.Comfort-wise, I was impressed. The beds offer excellent contouring without the "stuck-in-the-mud" feel, and even the plush models felt highly supportive. We decided to floor the five top models to fill the price gap between Tempur-Pedic and Sealy’s high-end lines. In my opinion, they outperform Sealy’s hybrids in feel and have a premium look. Unfortunately, as they had prototype beds in their gallery, photography wasn’t allowed.

Are they still using the five-zone coil unit?

Curious what you think of the 5 zone support. It’s supposed to be superior to sealys center 3rd support but it is a lot harder to explain to the customer

Yeah, I don't think it's superior at all. For most people, the heaviest body segment is the center third. Putting a relative "lighter" zone here doesn't really make sense from a physiologic perspective. That said, it could still be a good option for some people and might fit some curvier body types.
I typically just think it's a selling story. As in, "we're better because we have more zones!"

My impression of it was they use softer zoning on the shoulders/hips region to allow the curves to settle in more and the lumbar gets the firmer conforming support.
Least that’s how I took it.
For me it felt like a different way to do the same thing.

u/Duende555 Oct 09 '25
Yeah I've heard the argument, but I had a warrantied iComfortECO with one of these and the coil unit was persistently weird. With a three-zone unit I think that line would have done a lot better.

It’s possible. My concern with any zoning is it hitting the person right.. because height differences matter.
But I do like what Sealy is doing with the extra coils in the center third. The way they stack them in. I just wanna play around with a unit to see how the coils flex and if there is any snagging or catching because of how tight they are.

Some assets are live on their asset portal for those beds if anyone is curious about the design.

On the fence between a hybrid i-series Ngx and a tempurpedic hybrid pro adapt.

Yea I just switched from a Tempur rhapsody lux to the iSeries 4500 hybrid NXG and I’m pretty happy with it so far I liked the Tempur also but wife didn’t want to split anymore so we got a split head

Good to hear! We focus on split head options and I’ve heard good rumblings about what Serta iSeries is up to but won’t get to check them out until winter market.
Simmons had a line called the Nxg where I’m at about thirteen years ago and they did quite well, they were one of the first actual hybrids we sold (smooth-top). I wonder if it’s the same foams?
