Overview: Alexander Signature Mattress

The Alexander Signature mattress is a 12.5”, five-layer mattress made with two layers of premium memory foam, two layers of polyurethane comfort foam, and topped with a plush, quilted pillow top.

In our evaluations, we found the Alexander Signature mattress to have a Medium softness level (it is also available in a Firm version). In our tests, we found this bed to offer very good support and spinal alignment for those who sleep primarily on their backs and sides, along with excellent pressure relieving properties, owing to the four-inch layer of high quality memory foam up top.  

Those two memory foam layers—a 2.5” layer of 4-lb. density memory foam and a 1.5” layer of 4.5” memory foam—are both soft and firm, and in our tests, found that as much as they provide superior pressure relief, they also help support lighter and concave parts of your body, such as your lumbar area.

If you like to sit on the side of your bed, or lay right on the edge, the Alexander Signature mattress is an excellent choice. Memory foam beds in general have a poor reputation for edge support, but our tester felt stable and supported in both positions. If you have kids or pets that tend to push you towards sleeping right on the edge, this Nest mattress deserves consideration.

The Alexander Signature mattress also excelled in our tests for motion isolation, making it a good choice for those who are sensitive to the movements of others on the opposite side of the bed.

Value-wise, the Alexander Signature bed is an excellent deal, with high quality materials that would cost much more in a mattress store. The company offers a 100-day trial period, giving you a good measure of peace of mind. And if you prefer to try before you buy, Nest does have about a dozen showrooms, mainly in California and Arizona (see Nest Store Locator).

On the other hand, we were not as excited about the bed’s suitability for stomach sleeping. Our 200-lb. tester’s hips sunk too deeply into the mattress and created some over-arching in the spine rather than the neutral spinal position we’re looking for. We think the issue will be even more pronounced for heavier individuals.  

Free shipping is included, though in-home setup costs extra.

Note that the Nest mattress does not come with a box spring (nor does it need one). You can place the Alexander signature mattress atop the support of your choice, including a separately purchased box support, a bed frame, platform bed, or adjustable bed frame. Nest sells its own bed frame but it's not a required purchase.

Overall, the Alexander Signature mattress performed very well in our testing and evaluations. We judged construction to be of excellent quality and would not have concerns about longevity or durability.

 Read on for our detailed report and be sure to check out the video to see this mattress in action as we put it through our tests.



Mattress type:  Gel Memory Foam over Foam

Made In:  United States

Mattress Thickness:  12.5"

Mattress Weight:  80 pounds (queen size)



The Alexander Signature mattress is a 12.5″ thick mattress comprised of 5 layers (listed below from top to bottom):

  • ½” quilted pillow top/cover
  • 2.5” gel memory foam comfort layer, 4 lb. density
  • 1.5” visco memory foam, 4.5 lb. density
  • 2” polyurethane foam support layer, 1.8 lb. density
  • 7” polyurethane foam support layer 1.8 lb. density

The Alexander Signature mattress by Nest Bedding is made of five foam layers stacked and glued together. Four total inches are memory foam, with nine inches of polyurethane foam as the support layers. The quilted pillow top also adds padding and loft to the bed. While the company measures it at ½ inch, it seemed more like an inch to us.

Nest does provide density numbers for its foams. Between 4 and 5 lb. densities for memory foam typically designates the highest quality. Nest Bedding is great about disclosing those densities; not all companies do.


The five layers of the Alexander Signature mattress are wrapped in a very plush quilted pillow top and cover. It isn’t removable, so the cover is an integrated part of the mattress.


Comfort & Feel

There are three aspects that make up our assessment of comfort and feel. We call these "preference-based characteristics" because no rating here is better or worse – rather, the attributes that are most desirable to you will be determined solely by your personal preferences. We apply the same classification standards to each mattress so you can more easily compare apples to apples.

Softness ( what’s this )

Keep in mind that what mattress companies call “firm” or “soft” is a purely a preference. All mattresses should be supportive and promote healthy spinal alignment. Whether a mattress is fluffy and squishy (what mattress companies call soft or plush), or less so (what companies call firm), is purely down to your personal needs and preferences.

The Alexander Signature mattress comes in two versions: Medium and Luxury Firm. We tested the Medium version and found that it did feel like what we would class as Medium softness.

Not sure what softness is best for you? Take our Mattress Match Quiz and find out.

Softness Level
(1=Least Soft, 9=Most Soft)
5 Medium


Cushioning Depth ( what’s this )

This refers to how deeply you sink into the mattress or feel cradled or hugged, versus a feeling of floating on top of the bed. We found the Alexander Signature from Nest to have a bit deeper than average cushioning, and our tester felt slightly more in contact with the mattress than average. Keep in mind that we tested the Medium version of this bed. It also comes in a Firm version, which we would assume has less cushioning.

Cushioning Depth
(1=Shallowest, 9=Deepest)
6 Slightly deeper than average cushioning


Responsiveness ( what’s this )

Responsiveness refers to how quickly a mattress recovers its shape after being compressed. When you press your hand into the mattress, for instance, then remove it, does it take several seconds for the mattress to return to flat, or does it recover immediately?

The Nest Alexander Signature bed has four inches of memory foam, so we were not surprised to find plenty of that slow, melting-into-the-bed sensation. Our tester, for instance, felt his hips sink more deeply into the mattress after a few seconds, when his body began to warm the memory foam layers.

Because of the thick quilted cover on the mattress, which is not made of memory foam, our tester did note that lighter parts of his body, like hands and feet, really didn’t contact the memory foam. The feeling overall on the Alexander Signature bed was a bit of a hybrid. Our tester’s hips and shoulders sunk pleasantly into the bed, while lighter parts floated more on top.

Back Support & Pressure Relief

The two things that you should always be sure to get from your mattress are spinal alignment (commonly thought of as "back support") and pressure relief. Unfortunately, no mattress will deliver these two things equally well for all sleepers. In particular, spinal alignment and pressure relief capabilities will vary across sleepers with different weights, body shapes, and sleep positions. To help you determine how this mattress will perform for you, we break down our spinal alignment and pressure relief assessments by sleeper type.

In our evaluations, the Alexander Signature mattress from Nest Bedding afforded very good back support and spinal alignment particularly for back and side sleepers. The foam densities at the top of this mattress are high, which means that those comfort layers are also playing a support role, translating to very good performance when it came to back support.

In the stomach sleeping position, however, our tested noted that his hips sunk too far into the mattress, creating less than ideal spinal alignment. This is a concern with all memory foam mattresses, where your body just keeps sinking into the memory material. Hips that sink too deeply in the stomach position can create too much arch in the back, and that can lead to back pain.


Spinal Alignment

The key to good back support is maintaining proper spinal alignment while you sleep. This means that the mattress should hold your spine in roughly the same position it's in when you're standing. The ability of a given mattress to do this will generally depend on your weight, sleep position, and body shape.

Here is how we break down the spinal alignment of the Alexander Signature mattress from Nest.

Weight Range Back Sleepers Side Sleepers Stomach Sleepers
Lighter <150 lb 9 9 7
Average 150 to 200 lb 9 9 7
Above Average 200 to 250 lb 9 9 6
Heavier >250 lb 8 9 6


Back Sleepers:

While our tester was on his back, he noted that his hips sank just deeply enough to create a good neutral spine. The memory foam, while responsible for cradling his hips and shoulders, was also supportive. We feel that sleepers of a wide weight range would have a similar experience.

Side Sleepers:

In our evaluation, side sleepers would be well supported by the Alexander Signature bed. Our 200 lb. tester’s hips and shoulders sank into the bed just enough to create a neutral spinal position. Overall, if you sleep primarily on your back and side, like the majority of people, then we think the Nest bed will suit you very well.

Stomach Sleepers:

Achieving good spinal alignment for stomach sleepers can often be trickier as the hips can tend to sink down too far with some mattresses, and we felt this was the case with the Alexander Signature mattress, particularly for heavier (over 200 lbs.) individuals who primarily sleep on their stomachs.


Pressure Relief

When a mattress pushes back against your body with too much force in a concentrated area, the result can be pain, soreness, loss of circulation, excessive tossing, and other problems. In general, such "pressure points" are of greatest concern for side sleepers, since that's the position in which your body's weight is distributed over the smallest surface area. To find the right mattress for your needs, keep in mind that the pressure-relieving capabilities of any given mattress will vary depending on the sleeper. Factors like your weight and body shape (e.g., broader shoulders and/or hips) will determine how far you sink into the mattress, and the pressure relief offered by that mattress will vary widely at different depths.

Here's how we sized up the pressure relief of the Alexander Signature mattress:

Weight Range Typical Curves Extra Curvy
Lighter <150 lb 9 9
Average 150 to 200 lb 9 9
Above Average 200 to 250 lb 9 9
Heavier >250 lb 9 9


Overall, we found the pressure relief offered by the Nest mattress to be excellent. Our tester had no issues with pressure points, and because there is so much memory foam in this bed, we don’t think many people would have trouble with this. As his body warmed the memory foam, our tester felt himself sinking even just a bit deeper.

Other Characteristics

Beyond the preference-based characteristics of comfort and feel, and the body matching for spinal alignment and pressure relief, a mattress will have a number of other attributes that can make it a better or worse choice for you. We call these "priority-based characteristics" because they are areas in which a mattress can be better or worse, but that will have differing amounts of importance to each sleeper. So, determining how much importance to give to these features will be entirely a matter of your own personal priorities. As always, we apply the same ratings standards to each mattress so you can more easily compare apples to apples.


Motion Isolation ( what’s this )

As we would expect from a mattress containing this much memory foam, motion isolation was a highlight in our testing. We felt that the Alexander Signature bed would be an excellent choice for couples who don’t want to feel their partner getting in and out of bed. Movements on one side of the bed were barely perceptible on the other.

Motion Isolation Rating
10 /10 Exceptional


Temperature ( what’s this )

For most people, we do not think the Alexander Signature mattress will feel hot. Memory foam has a reputation for heat retention, but in the case of the Alexander Signature bed, the memory foam layer is quite in top—it’s under a heavy quilted cover that doesn’t contain any memory material. The company also claims that the cover is made with phase-change material, meaning it should feel cool to the touch. We did not note that it felt different than regular fabric.

If overheating in bed is an issue for you, and you’ve experienced it with other mattresses, other models have features that are specifically intended to address this, but for most we don’t expect heat to be a problem with the Alexander Signature bed.

Stays "Cool" Rating
8 /10 Good among foam beds


Edge Support ( what’s this )

Foam mattresses aren’t typically very supportive along the very edge of the mattress—important if you like to sit on the edge of the bed, or if you tend to sleep along the edge. With the Alexander Signature mattress, our tester did experience a substantial amount of dip when sitting on the edge of the mattress, but he never felt unstable at all.

When laying on the very edge of the bed, our tester also felt very stable, and did not feel like he was leaning or rolling off the bed at all. If your pets or kids tend to push you towards the side of the bed, we think the Alexander Signature bed will get you the most usable space out of your mattress.

Edge Support Rating
9 /10 Excellent


Ease of Repositioning ( what’s this )

If you tend to move and change positions a lot over the course of a night, ease of repositioning will be a priority for you. With memory foam beds, owners often report that it can be hard to roll over and feel as if they are rolling out of a hole. But because the memory foam material is under a plush cover, we felt this mitigated what can be a trouble spot for memory foam beds in general.

Our tester did not experience any problems rolling from position to position.

Repositioning Rating
8 /10 Very good


Green Features ( what’s this )

For mattress shoppers concerned with the use of natural materials, sustainable manufacturing practices or the like, we offer our subjective evaluation of any efforts taken by the company to make the mattress more green, healthy, or safe. 

In the case of the Alexander Signature mattress, the foams used are not natural; however they are certified to the CertiPUR-US standard, which verifies that a material has low VOC off-gassing as well as a lack of chemicals and other substances regulated by the CPSC.This type of certification is not ususual; it's become the standard for brands making beds with petroleum-based foams.

The company also says that its fire sock (a fire retardant required by law) is made of natural silica.

Green Rating
4 /10 Okay


Adjustable Base Compatibility ( what’s this )

While we did not test the Alexander Signature mattress on an adjustable base, but Nest says that an appropriate frame will not harm the mattress.

Adjustable Base Use Rating
8 /10 Very compatible


Price, Value & Longevity

What It Costs

Prices shown are list prices. Remember that GoodBed keeps our site current with the best available discounts on online mattresses, many of which are exclusive discounts for our readers.


What You’re Getting

The Alexander Signature mattress from Nest Bedding is a 12.5” mattress with four inches of premium memory foam as its comfort layers. The quality of these memory foams is excellent, with 4 and 4.5 lb. densities. The non-removable cover of the mattress has a plush and heavily quilted top. In our time testing the Nest bed, we found it to be sturdy and well made. It’s also worth noting that user reviews for this bed on GoodBed are some  of the highest satisfaction ratings we’ve seen for any mattress.


How Long We Think It Will Last

When it comes to estimating the comfort lifespan of a mattress, we tend to use foam density as our best, albeit imperfect, predictor of how long a foam will retain its shape and resiliency. In this case, the top two memory foam layers on the Nest bed are of high 4- and 4.5-lb. density, which we think will last a long time. The lower layers are a very standard 1.8-lb density polyurethane foam, a material that’s time-tested. Overall we think the Alexander Signature bed will last a long time without the foams breaking down.


Overall Value

We were very impressed by the Alexander Signature mattress by Nest Bedding. The materials used in its manufacture are of very high quality, yet the price ($1,199 for a queen size) is in line with its online competition that use lesser-density foams.

And if you prefer to try a mattress in a store, Nest does has a handful of showrooms, primarily in California and Arizona so you can try before you buy. Otherwise, take comfort that the company offers a 100-night trial, and if you’re not happy for any reason after trying the mattress, you can get a full refund.

Value Rating
9 /10 Excellent


Delivery, Returns, & Warranty


  • Free delivery to door

Nest Bedding includes free delivery, which is not particularly unusual among its competitors. Delivery is by common carrier like FedEx, who will deliver the box to your door. Nest does offer an in-home setup at extra cost, calculated depending on where you live.



  • 100-day trial period
  • Full refund

Nest offers buyers a 100-day trial period, and urges buyers to give the mattress at least 30 days before initiating a return. Upon proof of donation to charity, the company will refund your money. It’s up to you to find a charity that will accept the mattress. See: Details of the Nest Bedding return policy for the Alexander Signature Series mattresses.



  • Warranty Length: Lifetime
  • Indentation Coverage: 1” and above

One of the biggest, if not THE biggest complaints about any mattress from consumers regards body impressions—the inability of a mattress to spring back, eventually creating a low spot/sinkhole in the mattress. As such, mattress warranties all contain a term defining how big a sag or ‘body impression’ (measured when no one is on the mattress) is considered a defect, and thus covered under the warranty. The industry standard for mattresses is generally between ¾” and 1.5”. Nest Bedding has chosen to cover indentations that meet or exceed 1”. Practically speaking, that means any softening or sagging would need to be at least that deep before the warranty would offer you protection.

This warranty extends to the original owner for as long as they own the mattress, and assumes it has been placed upon an appropriate foundation. See: Nest Bedding warranty info.
