Nolah Evolution 15 Review: A Cooling Mattress for Hot Sleepers

Every product we offer has been independently selected and reviewed by our editorial team. If you make a purchase using the links included, we may receive commissions.

If you’re a hot sleeper, you will likely be referring to my nightly routine. Not only do I turn up the A / C before I go to bed, but I also have a 23-inch fan on my face after I slip under the sheets. As for the winter months, the only thing that changes is what I do with the thermostat – the artificial breeze from my fan is a must all year round.

At some point in the past few years I’ve gone from being a hot sleeper to a hot sleeper who wakes up drenched in sweat no matter how cold she makes her bedroom. I’m embarrassed to say it took me months to admit that my mattress contributed to the problem. Although I was reluctant to get rid of my snuggly pillow-top mattress, I knew that I would be much more comfortable on a mattress with some cooling properties. So I took the plunge with the online mattress brand Nolah, specifically the most popular bed in their range: the Evolution 15.

Evolution’s materials include ArcticTex fibers and graphite-infused AirFoamICE that sounded like the frosty level I was looking for. Since then, I’ve been sleeping on Nolah’s luxurious hybrid mattress for more than 100 nights and now wake up more refreshed than damp. That’s how I fell in love with my Nolah bed.

My Nolah Evolution 15 review

To make an overall rating for the Nolah Evolution 15, I tested the bed for 100 nights. I also compared the price, warranty, and trial period of the mattress to other bed-in-a-box brands. This is how evolution stacks up.

Features of the Nolah Evolution 15 mattress

The Nolah Evolution 15 is a hybrid mattress made of graphite-enriched foam and coils. The 15 refers to the thickness of the mattress which is 15 inches no matter what size you order. Although the bed is marketed for side, back, and combination sleepers, it appears to benefit side sleepers the most.

The Nolah Evolution 15 is available in three degrees of hardness: Plus, Luxury-Firm and Firm. I chose Luxury-Firma, which is 6.5 out of 10 points on the hardness scale. The quilted Euro top part of the mattress and the 2-inch layer made of highly elastic foam offer enough comfort and cushioning for me as a side sleeper. And thanks to the three-part support coils – as well as the high-density foam base that stabilizes them – I never have the feeling of sinking into the surface.

I never really thought about whether my spine would stay in line during the night until I wrote this review. I’m lucky enough not to have a lot of back pain, and I’ve never woken up from sleeping on this mattress. Plus, I always sleep on the same side of the bed, and unlike other mattresses I’ve owned, there’s no indentation in my body shape, which I attribute to the responsiveness of the coils.

My main reason for testing the Nolah Evolution 15 was because it was branded as a cooling mattress. I was sick of being hot and this bed promised a lot of relief. Although it doesn’t feel cool to the touch, the cover’s ArcticTex fibers actively wick excess heat away from my body while I sleep. I don’t feel suffocated under the covers anymore.

Nolah’s graphite-infused proprietary foam known as AirFoamICE also helps keep night sweats at bay. Is it like sleeping on an ice pack? No. But the fact that I no longer feel sticky in the morning should tell you all about evolutionary cooling technology. It is important to note, however, that I also sleep on Buffy eucalyptus sheets that I purchased because they are thin and highly breathable. Hot sleepers should invest in light sheets and a cooling duvet if they are really concerned about overheating at night.

Beneath the Evolution’s cooling layers are 2 “of high resilience foam, 1” of reactive transition foam, and 8 “of three-zone coils. These three levels work together to provide full body support and exceptional pressure relief. But it’s the quilted euro topper that won’t get me out of bed in the morning. It’s so soft that I can easily fall asleep most nights. While I haven’t struggled with back pain, I would recommend this mattress to people who do because after a particularly hard workout, I’ve found it cushions common pain points in the lumbar region.

If there’s one area where the Nolah Evolution 15 falls short, it’s edge support. This refers to the thickness of the edges of a mattress: can you sit on the edge of the bed? Does it feel like you can roll off during the night? I had high hopes for evolution as it is constructed using Nolah’s proprietary EDGE support grid system that encases the core structure on all four sides. However, I find the sides a bit thin.

A couple of times in the nearly four months I had the mattress, I thought I might fall off. And I usually avoid sitting on the edge of the bed to tie my shoes. While the pros far outweigh the cons here, I wish I felt more secure at the edge of the mattress. Because of this, I don’t think the queen size will suit most couples. A king or a California king has more room to spread out from the edge.

Nolah delivery and packaging

Delivering my Nolah mattress was incredibly easy, but unpacking it was a whole different story. My Queen-Size Evolution arrived in a tall, narrow box three weeks after I ordered it. It was left in the mail room of my apartment building in good condition (which I expected) but I was shocked at how heavy it was (easily over 100 pounds). To be fair, the brand recommends on their website that two people take the box to the room they need, but as a single woman I didn’t have this option. I actually had to recruit someone from my house to help me get the box to the elevator and drag it to my apartment door.

Nolah claims that the actual setup takes 10-15 minutes, but it took me about 45 minutes since I did it on my own. After getting the rolled up mattress out of the box, which was honestly the hardest part, I put it on the bed frame before peeling it apart from layers and layers of plastic wrap. It expanded to its full size quickly, so I’m glad I thought to put it on the box spring bed first. If I ever have to move this mattress again, you’d better believe I hire professionals. But in this case, heaviness means durability, and I am confident that I will sleep on the Nolah Evolution 15 for many years to come.

Nolah mattress price

If you are still unsure about the price, just take a look at the functions of this hybrid mattress: an ArticTex cover, a quilted Euro topper, graphite-reinforced AirFoamICE. In my book, evolution is a worthwhile investment.

Nolah trial period and warranty

You don’t have to go to a mattress store to test a bed. Nolah allows you to try out its mattresses for 120 nights. If you find that the bed is not right for you during this 120 night period, Nolah will refund you the full amount and send a driver to collect the mattress for free. The brand recommends sleeping on the bed for at least 30 nights to let it shrink.

The Nolah Evolution 15 also comes with a lifetime limited warranty, meaning it is only valid for the first-time purchaser of the mattress. For the first 15 years, Nolah will repair or replace your mattress at no additional charge if it is found defective. After this period has expired, the buyer will be invoiced proportionate replacement and processing fees.

Nolah customer service

To be completely honest, I didn’t spend a lot of time interacting with customer service, but Nolah makes it easy to get in touch with a rep. The company has a “live chat” feature on its website, but you can also contact customer support by phone (866-403-6615) and email ([email protected]).

Reviewers say that Nolah staff took the time to explain what each mattress had to offer and helped them decide which firmness level to get based on their sleeping position.

Nolah customer reviews

On Nolah’s website, the Evolution 15 has an average of 4.9 stars out of 5. Although my first review site is Trustpilot, Nolah only has one review there, so I took the 3.3 out of 5 rating with a grain of salt. Here are some new customers’ opinions on the Nolah Evolution 15:

“I love this mattress. I used to have hip, knee and shoulder pain all night. Now I sleep all night and wake up rested, which means a great day ahead of us.”

Kim B., 5 out of 5 stars

“It’s the best mattress I’ve ever had for back pain relief and I feel good all night. I also enjoy the pillows. The only thing I don’t love is that it’s a little thicker than the mattresses we’ve ever had, and it was. It’s hard to keep fitted sheets on. ” – Ashley D., 4 stars out of 5

“My husband would give this mattress 5 stars. I give it 3 stars … I sleep on my side and wake up with neck pain every day since sleeping on this mattress. My husband has a stomach / back / side sleeper and he finds it very comfortable . ” – Kerri C., 3 out of 5 stars

“The Evolution 15 mattress is great – very comfortable and supportive. Shopping was easy, the only ‘better if’ was knowing how long delivery would take and better tracking information. (I sold my old mattress two weeks ago arrived!) “- Alan K., 5 out of 5 stars

Nolah Evolution 15: Final Take

My overall rating for the Nolah Evolution 15 is 8.9 out of 10. This mattress helped me sleep cooler and more comfortably thanks to its unique hybrid construction and high-tech materials. Although I would prefer stronger edge support and wasn’t a fan of the furnishing phase, I recommend this bed to hot sleepers who need a little relaxation and any side sleeper who appreciates a medium firm feel.
