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 particularly successful with its 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 and it is also flippable, which offers two firmness options in one mattress.

I thoroughly enjoyed the original Nolah mattress, and I was excited to try out this flippable mattress; to find out if both sides are comfortable, read on for my full review!

The Nolah 12″ Mattress Should Work For …

  • Side sleepers who need pressure relief. The soft side of the mattress relieves pressure quite well so that I feel no significant pressure on my shoulders or hips – our staff writer Marten, who is heavier, also thought the soft side relieved pressure well, so the soft side of this mattress could be a fantastic option for side sleepers of many sizes.
  • Hot sleepers who need extra cooling. Foam mattresses are not always the best at keeping sleepers cool at night, but that is not the case with the Nolah 12″ Signature mattress; this mattress helps dissipate heat, so the majority of sleepers shouldn’t be overheating.
  • Heavier sleepers who don’t want to bottom out. The Signature mattress is thicker than the original 10” Nolah mattress and, 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 they shouldn’t compress this and hit the firmer support layers beneath.

The Nolah 12″ Might Not Work For …

  • People who want a medium-firm mattress. Even though this mattress is flippable, the firm side may be too firm for some; the soft side may feel extremely soft if someone wants a mattress with an average firmness.
  • People who switch positions at night. The mattress is a fantastic match for side sleepers on the soft side and an excellent match for back and stomach sleepers on the firm side. This flippable nature gives sleepers many options, but if someone switches positions often during the night, they will have to actually flip the mattress for it to be a good fit.

Construction Overview

  • The Nolah Signature mattress is 12” tall.
  • First, there is a soft, thin cover that is removable so that one can flip the mattress.
  • The next layer contains 2.5” of Cooling Nolah AirFoam which offers excellent pressure relief.
  • Then, there is a transition layer that consists of 1.5” of Deep Supportive High-Resilience Foam – this transitions sleepers from the soft upper layer down to the support layer.
  • This is followed by 7” of a Reinforced High-Density Core Foundation foam which is the durable center of the mattress.
  • Finally, there is 1” of Cooling Nolah AirFoam, which is also the top layer of the firm side of this mattress.

Construction Takeaways

  • The Nolah 12” mattress is available in the standard sizes: Twin, Twin XL, Full, Queen, King, and California King.
  • The AirFoam on both sides of the mattress is designed to dissipate heat, so the majority of people shouldn’t be overheating on the Nolah 12″ mattress.
  • The mattress is flippable, so there are two firmness options in one mattress – one side has a thicker comfort layer, so it is better for side sleepers, and the other side is thinner in terms of its comfort layers, making it ideal for stomach sleepers and back sleepers.
  • The AirFoam is quite responsive, so the majority of people should get nice pressure relief without feeling “stuck” in the mattress when they try to reposition themselves.

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. In addition, the 12″ Signature mattress is flippable while the original is not.

This means a few things for different sleepers – heavier sleepers may find the 12″ mattress is a better fit for them because it is thicker, and there is less chance of them bottoming out on this mattress. This occurs 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 more appropriate option 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 more appropriate option 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 and provided me with some good pressure relief on my shoulders and hips. However, this side felt a little too soft when I was stomach sleeping.

The firm side felt like a 7.5/10 on a firmness scale, or firmer-than-average – this side was an exceptional match for me when I was on my back and stomach – I felt the appropriate amount of support, and my hips didn’t sink in too far.

On both sides of the Signature, the mattress has a pleasing foam feel; it allows people to sink in a bit, so they have more of that “sleeping in” the mattress feel, but they 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 people can move around on the mattress easily, getting pressure relief without feeling stuck.

Motion Transfer

Being that it is an all-foam mattress, I expected the Nolah Signature to perform well with motion isolation; during my tests, I saw very little motion transfer and, when I disturbed the area around the glass, it barely moved.

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

Sleeping partners shouldn’t be disturbing one another at night, so I think this could be an appropriate mattress for couples.

Edge Support

All-foam mattresses don’t always have the best edge support, and that is the case with the Nolah Signature; 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 but, that being said, the edge support wasn’t very good on this mattress.

Marten’s Take

Marten is a staff writer for us, and he has a particularly different body type than me: He is 6’7″ and weighs about 230 lbs; I am 5’9″ and 160 lbs. Here is what he thought about the Nolah 12″ Signature mattress:

Joe felt the mattress was approximately 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, and I feel very comfortable in this position; on the soft side, when I am stomach sleeping or back sleeping, I think I require 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, so it’s definitely not the best for side sleeping. Stomach sleeping, I still need more overall support but, back sleeping, I feel the appropriate amount of overall support.

That being said, if someone is my size and a side sleeper, I would go for the soft side of the Nolah Signature; if they are my size and a back sleeper, I would go for the firm side of the mattress. 

However, if someone is are a stomach sleeper and they’re my size, they should 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.

What Makes The Nolah 12″ Mattress Stand Out?

  • The soft side is an appropriate match for side sleepers because it relieves pressure particularly well on the shoulders and hips.
  • Even though it is an all-foam mattress, the Nolah Signature dissipates heat well; people shouldn’t be overheating on the mattress.
  • The Nolah Signature is flippable, so there are two firmness options in one bed-in-a-box mattress.
  • The foam on both sides offers people that sinking-in feeling, but it is fast to respond; this makes it so people 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 the customer – people 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 the bed.

Carefully cut away the first layers of plastic until the still-compact mattress can be laid down flat, pierce through the final layer of plastic, and the Nolah Signature will expand – simply clear away the excess plastic and allow the mattress to breathe and completely expand.


I enjoyed my experience on the Nolah 12″ mattress – the soft side provided exceptional pressure relief on my shoulders and hips; the firm side was appropriately supportive when I was on my stomach and back.

While some heavier sleepers may need a firmer mattress when they are stomach sleeping, I think this 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.

Also, a portion of each purchase will go to saving an animal of each customer’s choice.
