Nolah 12″ Mattress Review – Multiple Comfort Options?

We receive free products to review and participate in affiliate programs. See our disclosure page for more information.

Nolah has been quite successful with their original Nolah 10″ mattress. It is a value mattress with pressure relieving and cooling components.

The new Nolah Signature 12″ mattress offers a few features that the original Nolah 10″ mattress does not. The 12″ is thicker with more of a comfort layer. Also, it is flippable, which gives you two firmness options in one mattress.

I enjoyed the original Nolah mattress, and I was excited to try out this flippable mattress. Will you find comfort on one of the mattress’s two sides? Read on for my full review.

You Will Like The Nolah 12” If …

  • You are a side sleeper. The soft side of the mattress relieves pressure quite well. I felt no real pressure on my shoulders or hips. Our staff writer Marten, who is heavier, also thought the soft side relieved pressure well. The soft side of this mattress could be a good match for side sleepers of many sizes.
  • You are a hot sleeper. Foam mattresses are not always the best at keeping you cool, but that is not the case here. This mattress helps dissipate heat, so you shouldn’t be sleeping hot.
  • You are a heavier sleeper. This mattress is thicker than the original 10” Nolah mattress. Because of this, heavier people shouldn’t have to worry as much about bottoming out on the mattress. There are 4” of comfort layer on the soft side, so you shouldn’t press through to the firmer support layers beneath.

You May Not Like The Nolah 12″ If …

  • You want a medium-firm mattress. Even though this mattress is flippable, the firm side may be too firm. And the soft side may be too soft if you want a mattress with an average firmness.
  • You are a combination sleeper. The mattress is a good match for side sleepers on the soft side and a good match for back and stomach sleepers on the firm side. This flippable nature gives you many options, but if you switch positions often during the night, this may not be the best fit for you.

Construction Overview

  • The mattress is 12” tall.
  • First, there is a soft, thin cover. It is removable so that you can flip the mattress.
  • Next, there are 2.5” of Cooling Nolah AirFoam.
  • Then, there is a transition layer. It is 1.5” of Deep Supportive High-Resilience Foam. This moves you from the soft upper layer down to the support layer.
  • This is followed by 7” of a Reinforced High-Density Core Foundation foam. This is the durable center of the mattress.
  • Finally, there is 1” of Cooling Nolah AirFoam. This is the top layer of the firm side of this mattress.

Construction Takeaways

  • The Nolah 12” is available in Twin, Twin XL, Full, Queen, King, and California King.
  • The AirFoam on both sides of the mattress is designed to dissipate heat, so you shouldn’t be sleeping hot.
  • The mattress is flippable, so you have two firmness options in one mattress. One side has a thicker comfort layer, so it is better for side sleepers. The other side is thinner in terms of its comfort layers, so it is ideal for stomach and back sleepers.
  • The AirFoam is fast to respond, so you should get nice pressure relief without feeling “stuck.”

How This Mattress Compares To The Original Nolah

There are a few clear differences between this mattress and the original Nolah. First, this mattress is thicker overall. As the name suggests, it is 12″ thick, while the original is 10″ thick. Also, the 12″ mattress is flippable, while the original is not.

This means a few things for different sleepers. First, heavier sleepers may find the 12″ mattress is a better fit for them. Because it is thicker, there is less chance of them bottoming out on this mattress. This happens when heavier people press through the comfort layers of a mattress right down to the firmer support layers.

The soft side of this mattress could be a better choice for side sleepers. It is plusher and the comfort layer of this mattress is 4″ thick (compared to only 3″ on the original Nolah).

The firm side of this mattress is also firmer than the original Nolah. This makes it a better fit for back and stomach sleepers compared to the original Nolah.

Check out my review of the original Nolah mattress HERE.


On the soft side, I felt like the Nolah 12″ was a 5/10 on a firmness scale, or softer than average. This side felt especially nice when I was on my side. It gave me some good pressure relief on my shoulders and hips. However, this side felt a little too soft when I was on my stomach.

The firm side felt like a 7.5/10 on a firmness scale, or firmer than average. This side was a good match for me when I was on my back and stomach. I felt good overall support, and my hips didn’t sink in too far.

On both sides, the mattress has a nice foam feel. It allows you to sink in a bit, so you have more of that “sleeping in” the mattress feel. You should definitely feel this more on the soft side.

That being said, the foam layers on both sides are also quite responsive. This makes it so you can move around on the mattress easily. You get pressure relief without feeling stuck.

Motion Isolation

Being that it is an all-foam mattress, I expected the Nolah 12″ to perform well with motion isolation. During my tests, I saw little motion transfer. I disturbed the area around the glass, but it barely moved.

I also had Marten move around on the other side of the mattress to mimic the motions a partner may make while you sleep. I barely felt his movement at all.

I think this could be a good mattress for couples.

Edge Support

All-foam mattresses don’t always have the best edge support. That is the case with the Nolah 12″. On both sides, I felt the mattress collapse when I sat near the edge.

Lying down near the edge, I didn’t feel like I was going to fall off. That being said, the edge support wasn’t very good on this mattress.

Marten’s Take

Marten is a staff writer for us. He has a much different body type than me: He is 6’7″ and weighs about 230 lb; I am 5’9″ and 160 lb. Here is what he thought about the mattress:

Joe felt it was a 5 on the soft side and then a 7.5 on the firm side. I thought it was more like a 5.5 on the soft side and a 7 on the firm side.

Starting with the soft side, I don’t feel pressure on my shoulders or my hips. I felt very comfortable in this position. On the soft side, when I was on my stomach and back, I think I needed more overall support.

Looking at the firm side, when I’m on my side, I feel a little too much pressure on my shoulders and hips. It’s definitely not the best when I’m on my side. On my stomach, I still needed more overall support. On my back, I felt the proper amount of overall support.

That being said, if you’re my size and a side sleeper, I would go for the soft side. If you’re my size and a back sleeper, I would go for the firm size.

However, if you are a stomach sleeper and you’re my size, I would consider a firmer mattress overall.

While I do think the firm side of the mattress should be a good match for most back and stomach sleepers, it is possible that the mattress wasn’t an ideal fit for a heavier person like Marten. He felt supported on his back, but he needed a bit more firmness to properly support him when he was on his stomach.

Still, he did not bottom out on this mattress. The mattress was thick enough to keep him from bottoming out.

What Makes This Mattress Stand Out?

  • The soft side is a good mattress for side sleepers. It relieves pressure well on shoulders and hips.
  • Even though it is an all-foam mattress, it dissipates heat well. You shouldn’t be sleeping hot.
  • The Nolah 12″ is flippable, so you have two firmness options in one mattress.
  • The foam on both sides gives you that sinking-in feeling but is fast to respond. This makes it so you won’t get “stuck” in the mattress.

Unboxing This Mattress

The Nolah 12″ is a bed-in-a-box mattress, which means it will come compressed and be shipped straight to you. You will want to begin by removing the rolled up Nolah 12″ mattress from its box. Then, preferably with another person’s assistance, position the roll on your bed.

Carefully cut away the first layers of plastic until the still-compact mattress can be laid down flat. Then, pierce through the final layer of plastic and the Nolah 12″ will expand. Simply clear away the excess plastic and allow your mattress to breathe and fully expand.


I enjoyed my experience on the Nolah 12″ mattress. The soft side gave good pressure relief on my shoulders and hips. The firm side was supportive when I was on my shoulders and back.

While some heavier sleepers may need a firmer mattress when they are on their stomach, I think this is mattress could work for a variety of sleeping styles.

The Nolah 12″ mattress comes with a 120-night sleep trial and a Forever Warranty. Free shipping and returns are available along with financing options.
