Nest Alexander Signature Series Mattress Review

Feel (Firmness) + Comfort


The Nest Alexander Signature Series is offered in Medium and Luxury Firm. The mattress comprises of 5 layers of foam, with the quilted first layer covered in stretched fabric. The height for the Medium and Luxury Firm are 12.5 inches each. 

Each firmness level is best suited to a specific sleeping position and the following are
Nest’s recommendations:


Side and back sleepers. According to Nest, the MEDIUM is preferred by 92%
of sleepers.


Best for back and stomach sleepers. 

The recommended firmness for you sleep position(s) may differ from the above-mentioned and the only way to know for sure what will work for you is to try the mattress firmness for yourself.

Fortunately, Nest Bedding offers a 100 night risk-free sleep trial, after which you can return it with free shipping for a full refund if the mattress does not work for you.

Once you’ve unboxed the mattress, it may take a couple of days for the bed to expand to its maximum capacity. Nonetheless, you’ll be able to sleep on it the same day that you unbox it.

Depending on the mattress size and weight, setting it up is fairly straightforward and easy to accomplish. Be aware that Nest mattresses range from 100 to 150 pounds, so it may require
two (2) people to set up.

On a scale of firmness out of 10, with 10 being the firmest, I would place each mattress at:

  • MEDIUM: 5 out of 10
  • LUXURY FIRM: 8 out of 10
mattress reviews


The overall comfort of the mattress is due to a good balance of cushiony memory foam and sufficient support. The two (2) inches quilted, covered layer has a definite plush feel to it and rests atop 4 inches of 4 pounds per cubic foot gel memory foam.

The three (3) subsequent layers comprise of good quality foam for support and spinal alignment. Altogether, the five (5) layers make for a satisfying and comfortable sleep experience.

If you find that the mattress is too firm for your liking, using the Alexander Signature Cooling Topper is a good option.

Overall Support

The general consensus among users is that the medium firmness has a soft, yet comfortable feel when you first lie on it, without compromising on support. Both side sleepers and back sleepers would benefit from it. However, if it’s a tad too firm for you, a mattress topper will do the trick. Stomach sleepers may want to consider the Luxury Firm to ensure adequate back support.

​The Gap Test is an accurate way to determine whether or not your spine is adequately supported, especially for the recessed areas of your body (your waist and lower back).

Sleep Metro Tip

To conduct the Gap Test, lie on your bed, check for the areas of your body that are not in direct contact with your mattress (typically your waist
and lower back).

Have your partner slide his or her hand between you and the mattress.
It should be difficult to do so. Make sure to conduct this test for
both the side and back sleeping positions.


Resiliency, or "push back," refers to how rapidly a mattress bounces back after pressure (such as your body when you are sleeping) is applied to it. The Nest Alexander Signature is unquestionably responsive to movement, which is a desirable feature for sleepers who don’t like a “sinking in” feeling on a mattress. It also makes changing sleeping positions easier.

Pressure Point Relief

The mattress is excellent for relieving pressure points. This quality is especially important for side sleepers, who are prone to experiencing hip and shoulder pain. In addition, individuals who have undergone hip or back surgeries reported that either they did not experience any pain or their pain had diminished considerably while sleeping on the mattress. Memory foam is known for its ability to conform to a sleeper’s body, and the Nest Alexander Signature is no exception.

Edge Support + Sinkage

One of the few complaints is that the edge support is not adequate, both in terms of sitting and lying on this mattress. Users reported that sinkage was markedly noticeable.

A Sinkage Test Determined the Following:

The first test involved sitting right at the edge of the mattress with most of the weight concentrated in a limited area. In this test the memory foam sinkage is approximately 4.5 inches to 4.75 inches when compressed.

The second test comprised of sitting farther back, with weight evenly distributed and not concentrated in one specific area of the mattress. For this test, the memory foam sinkage is approximately
3.25 to 3.75 inches.

The third test was conducted by lying stretched out at the very edge of the mattress. In this position, there is the feeling of rolling off the bed. The sinkage in this position is approximately 2 to 3 inches.

The fourth test was to determine the sinkage for side sleeping. The total sinkage is 1.5 to 2 inches. This is important to know, if you’re a side sleeper like me, and have a curvy body shape. Generally, my hips are prone to feel more pressure in a side sleeping position, so some "give" in a mattress is good for pressure relief. The sinkage of 1.5 to 2 inches works well for me.

The fifth test determined sinkage for back sleeping. In this sleeping position, the sinkage is 1.5 inch
to 1.75 inch.

The sixth test measured sinkage in a focused area in the center of the mattress. Here, the sinkage is 5.5 to 6 inches.

Noise Level

As is typical of a memory foam mattress, the Nest Alexander Signature performs exceptionally and does not output any noise. This quality is an advantage when you are sleeping with a partner, especially one who changes positions frequently. Couples who prefer sleeping on memory foam mattresses may also benefit from the lack of noise when engaging in intimate activities.

Motion Transfer

The Nest Alexander Signature is excellent at absorbing motion, so if you’re sleeping with a partner, you will find that you are able to change positions easily without disturbing him or her. If you sleep alone, you’ll be able to change positions easily without experiencing any sagging of the mattress or a
“sinking in” feeling.

Durability + Quality of Materials

The materials used in the Nest mattress are of high quality. The quilted cover comprises 2 inches of 1.5 pounds per cubic foot memory foam, which is the industry minimum standard for pounds per cubic foot. Generally for enhanced durability, I like to see at least 1.8 pounds per cubic foot of high density memory foam when it’s the top layer of a mattress. Nonetheless, it does not significantly detract from the overall durability and quality of the Nest. 

In addition, the subsequent layers of memory foam that make up the support (core), exceed the industry minimum standard for pounds per cubic foot. Overall, on a scale of “Fair,” “Good,” "Above Average" and “Stellar,” I would rate the Nest as “Above Average” for durability and "Stellar"
for quality.

Based on the density of the top 6 inches of memory foam, individuals with a low to normal Body Mass Index, or BMI (18.5 to 24.9), may be best suited to the Medium firmness. Individuals who are heavy or overweight with a high BMI (30 or greater), require more support and may want to consider the
Luxury Firm as a better option for them.

The 2-inch quilted cover is constructed of a stretch fabric that does not incorporate lycra and latex materials and has a soft, plush feel to it. Individuals who prefer their mattresses to “hug” them will appreciate the covers’ luxe feel. The aesthetic beauty and style of the mattress are an added bonus.


The subject of temperature seems to elicit mixed feelings. Some users think it sleeps hot, while others think it sleeps cool. Because of its closed cell construction, memory foam is generally notorious for sleeping hot. In this instance, and based on a total of 550 feedback comments from credible sources, including the Nest Bedding website, the majority of users (68%) think it sleeps cool.


Here again, the users are split as to whether or not they detected any off-gassing. The majority state that they did not detect any chemical smells, and those that did, state that the smell is minimal and dissipates after a couple of days.

What Is The Definition of a Bed Foundation?

A bed base, sometimes called a foundation, is the part of a bed
that supports the mattress.
The bed base itself is held in place and framed by the bedstead (bed frame).

Which Foundations Are Compatible?

Nest recommends resting your Alexander Signature Series mattress on a breathable, non-flexible box spring -- also known as a foundation -- or non-flexible slats with center support. Ensure that if your foundation consists of slats, they are no more than 4 inches apart.

Nest offers 3 types of foundations that work with all of Nest’s mattresses:  Homebase with USB Power Kit, Bi-fold Platform and Symmetry Adjustable Base.
Any one of these supports work well with an Alexander Signature Series mattress.


Customer Service

Nest has one of the best -- if not the best -- customer service for online mattress purchases. This is a company that highly values its customers and it shows in the way solutions are offered if customers run into an issue with their mattress. What amazes me -- and is almost unheard of for a CEO -- is that Joe Alexander, Nest’s Founder, responds personally to questions from customers.

Even the minimum number of customers who have returned their mattresses after their 100 night trial sing Nest’s praises. It’s important to mention that the returns were not as a result of lack of quality.

The personal attention that Nest’s customer service offers is phenomenal and sets the brand apart as one that genuinely listens. My personal experience in communicating with Joe during my research in writing this review undoubtedly has been positive.

Brand Transparency

Of the 394 reviews on Nest’s website, only 13 users rated the mattress less than 4 stars (3 users rated 2 stars and 10 users rated 3 stars). All of these 13 ratings were split between users’ expectations of the Medium firmness, which is largely based in personal preferences and in no way reflects poorly on Nest. Everyone of the reviewers agreed that the Nest mattress is top-notch quality and that the brand practices integrity and provides exceptional customer service.

The fact that the website clearly states the components of each of the layers within all of Nest’s mattresses as well as lists all of the reviews is proof that the brand practices transparency.

Accurate + Detailed Information on Website

The brand’s site is user friendly and the information is easily found. The Alexander Signature Series homepage provides the following:

  • A short video showing the production process of the mattress
  • Purchase options (mattress sizes + prices)
  • An image showing the mattress deconstructed, so that the layers are visible
  • Explanations of each layer
  • Reviews

Warranty + Return/Refund Policy

Nest offers a 20-year warranty for all Alexander mattresses (the warranty varies for Love & Sleep -- formerly The Love Bed -- and bedding accessories). Bear in mind that the warranty is valid only for mattresses that have not been abused by the purchaser, such as using the proper foundation to support the mattress as well as keeping it protected and free of any moisture. Manufacturing defects are also included in the warranty. NOTE: Mattresses must be unboxed within 30 days of delivery or the return privilege is void.


The following percentages for each point are based on 414 verified reviews from the credible sources, including Nest’s website.

Please note that the lower percentage for value for money is not reflective of bad reviews, rather the users focused their feedback mostly on recommendations and quality of sleep.

The majority of the reviews were 5-star ratings and 99.75% of the users were thrilled with the customer service and personal treatment they received (of the .25% that were not, Joe reached out personally to assist them and make them happy).
