Polices For The Nolah Signature 12 Mattress

Like pretty much every other mattress sold online, the Nolah Signature 12” mattress ships for free. Once you’ve placed the order, you will receive a tracking number, so you can watch your new bed travel to your doorstep.

The mattress will arrive compressed in a box. All you have to do is remove the packaging and allow the bed enough time to take its proper shape.

Nolah gives you 120 nights to make up your mind as to whether this mattress is the right fit for you. While you might be tempted to make a decision in the first few nights that you are trying out the bed, we urge you to give it at least a few weeks, as all new mattresses take some time to get used to.

Within the first 120 nights, should you ultimately decide that the Nolah Signature 12” bed is not the one for you, Nolah will give you a full refund during those first four months. Once you’ve returned the bed, Nolah promises to keep your gently used mattress out of a dumpster (after all, not many people will want to purchase a used mattress). Instead, they will either recycle the mattress through a local state program or donate the bed to a local charity so it can help out someone in need.

Assuming you decide to keep the Nolah Signature 12” for the long haul, Nolah offers a lifetime warranty. This is above and beyond the bed-in-a-box standard warranty of 10 years. What a lifetime warranty means is that if, at any point, you discover that your mattress has a defect (such as sagging or a deep indentation), Nolah will replace or fix your mattress, completely free of charge. You can read the full warranty on Nolah’s website.

How Much Does The Signature 12 Mattress Cost?

The Nolah Signature 12” mattress is a little more expensive than the average bed-in-a-box, but that’s because it’s not average—it’s actually a pretty unique mattress. Here’s a breakdown of pricing.

SizePrice (MSRP)
Twin XL$1,169
King / Cal King$1,769

Like every other online mattress company, Nolah is constantly running promotions, so in reality you should expect to pay a few hundred dollars less than the MSRP. You can check Nolah’s website for current discounts and deals or we should have a coupon code on this page for you.

Foam Layers And Construction

The Nolah Signature 12 is a four-layer, double-sided mattress. As you can see from the graphic below, both sides of the mattress utilize a layer of the proprietary “Cooling Nolah AirFoam.” The base layer is made with 1” of the AirFoam. This is just enough foam to provide support and pressure relief for all sleeping positions.

The next layer is what Nolah calls their Reinforced High-Density Core Foundation. It’s made with 7” of an “ultra-grade” core foundation foam. This layer provides the bulk of the support for the mattress. The second from the top layer is a “Deep Supportive High-Resilience Foam.”

This is a 1.5” soft, yet supportive layer of foam that provides pressure relief for side sleepers, and support for back sleepers. The top layer (again, assuming that the bed is lying the way it’s shown in the picture) is 2.5” of Nolah’s Cooling AirFoam. It’s a soft, accommodating layer that provides pressure relief for side sleepers in particular.

For those wondering what, specifically, Nolah AirFoam is, Nolah describes it as “fast responsive temperature-neutral “Memory Foam” with the bounce of Latex.” However, it’s technically a high resilience polyurethane foam that is made without the heat-trapping chemicals that is normally found in Memory Foam. The best way to explain it is that it feels like a mix of traditional memory foam and latex.

Nolah is included on the CertiPUR-US list of companies that guarantees their products are free from formaldehyde and cancer-causing substances.

The Nolah Signature 12” mattress is wrapped in an unbleached, thick, organic cover that does not have any harmful chemicals in it. It’s a really nice cover that actually smells quite good, especially as compared to the cover on most other mattresses.

While the cover is technically removable, we don’t recommend throwing it in the wash. It may shrink and be impossible to get back on your new mattress! Instead, if you spill something on your bed (perhaps you are enjoying breakfast in bed, and the syrup spills), we recommend spot cleaning. The easiest and best way to do this is to dampen a soft cloth with water and some detergent, and dab at the stain until it is gone.

Softness/Firmness Scale For The Signature 12 Mattress

The Nolah Signature mattress has a different firmness level on either side of the bed. In other words, one side is softer (we’d call it “medium” firmness), and the other is firm (we’d call it “medium-firm”). This essentially provides you with two mattresses, so you can choose which one is most comfortable for your specific sleep style.

Both sides of the Signature 12” mattress are equally responsive. In fact, we’d say this is a very responsive bed, which makes sense because the Signature 12” is made of a soft neutral-foam. Here’s a look at that.

As you can see, the mattress pops right back into shape after pressure is removed. This is particularly helpful for combination sleepers that rotate positions during the night. In fact, a more responsiveness mattress can help combo sleepers to get more restful sleep since rotating positions requires less effort.

Able To Accomodate Back And Stomach Sleepers?

Given that the Signature 12 mattress has two sides, each with a different firmness level, one side is naturally going to be better than the other for certain sleeper positions. For example, the firmer side will be more ideal for strict back and stomach sleepers. However, there is a lot of personal preference that goes into selecting a mattress. So if you are exceptionally petite, the soft side of the Nolah Signature 12” mattress may be supportive enough for back and stomach sleeping.

Will Side Sleepers Find It Comfortable?

The Nolah Signature 12” mattress should be comfortable enough for side and combination sleepers. Of course, personal preference will play a role here too, but we think the soft side of the mattress will be the best option. This is because the thicker layer of Nolah AirFoam should provide pressure relief where you need it around your hips and shoulders.

Keep in mind that a lot of this depends on your weight. If you’re on the heavier end of the spectrum, you may find the firm side provides enough pressure-relief.

How Is The Signature 12 For Heavier People?

For heavier individuals, we think the firm side of this mattress will be the best choice. We generally don’t recommend all-foam mattresses to heavy or obese people, but if you absolutely want a bed made entirely of foam, Nolah Signature 12 is actually not a bad option. Because it is flippable and slightly thicker, it will probably last longer than your average bed-in-a-box mattress. That said, if you weigh more than 250 lbs (what we consider heavy), you may want to look into a spring or hybrid mattress, which tend to be most durable than their all-foam counterparts.

Does Nolah Signature 12 Sleep Hot?

No. It actually does a pretty good job at regulating temperature. Nolah 12 is what we could consider “temperature neutral.” We didn’t find that it slept particularly hot or cold. And we actually see that as a good thing since the majority of people tend to sleep more neutral. If, however, you sleep really hot at night you might want to look into our list of the best cooling mattresses for hot sleepers.

Will Couples Like The Signature 12 Mattress?

If you are in a relationship and are not planning to purchase a king size mattress, you will want to get a bed with good edge support and motion isolation. We have good news if you are looking into purchasing the Nolah Signature 12” mattress; this bed is good with both.

Let’s break down what each term means for you. Edge support is important if you sleep in a smaller sized bed (such as a full or twin XL) with a partner. As anyone who has ever shared a bed knows all too well, it can be easy to end up on the edge of the mattress. Especially if it’s warm out, and you are trying to maximize your personal space. Since no one wants to feel like they’re about to roll off the bed, it’s important to choose a mattress that is supportive on the edges.

Actually pretty good edge support

A variety of people from our team tested the Nolah Signature 12” bed for edge support and we all found that it performed quite well. So that means you can comfortably sleep on the very edge of this bed and not feel like you’re going to end up on the floor.

Similarly, motion isolation is also very important if you are in a relationship or sleep with a partner. This is because occasionally people toss and turn (especially if you’re a combination sleeper) and in some mattresses, the motion can spread across the mattress and jolt the other person sleeping on the bed. So a mattress that isolates motion well will typically result in a more restful night’s sleep for both parties.

So how did Nolah Signature 12” do in this category? In short, very well. While typically the best motion isolating mattresses are made with memory foam, the Signature 12” holds its own well. Basically, the Nolah Signature 12” mattress is a good choice if you sleep in the same bed as a partner or large animal.

Nolah Signature 12 Review: Final Thoughts

All in all, this is a very accommodating mattress that we think will be a good choice for people who sleep on their back, stomach, side, or a combination of the three. Furthermore, this mattress is flippable so people with a wide variety of body types should be able to sleep comfortably. If you are in a relationship or sleep with a partner, the Nolah Signature 12” mattress will be a good choice, as well.

How did the Slumber Yard get the Nolah Signature 12" mattress?

We were sent this bed by Nolah in order to review it. We did not accept any money from Nolah to say good or bad things about their bed, however. We review products independently.

Why does Nolah say they adopt wild animals?

When you purchase a mattress through Nolah, you can choose your favorite wild animal. Nolah will then donate a portion of the proceeds to a charity that supports that animal.

What type of foundation should I use for the Nolah Signature 12”?

You can use the Nolah mattress on any flat surface. If you have a box spring or foundation already, you can use that. If you don’t already own one, you can use the floor just as easily. If you have a bed frame that utilizes slats, that is also fine, but Nolah requests they are less than 4 inches apart.

Is this mattress made in the United States of America?

Yes, it is! Nolah says the Signature 12” bed is 100% made in the USA.

Who Founded Nolah?

Nolah was founded by two award-winning entrepreneurs with a background in sleep material science and product design. The two co-CEO’s are Daniel Galle and Anna Hjoellund. Before Nolah, the duo invented SilkFX®, which is a washable silk filling for bedding products.
