Overview: Alexander Signature Flippable Mattress

The Alexander Signature Flippable mattress (as you might have guessed) can be used on either side. That's more unusual than you might think. Back in the day, when mattresses were basically springs and a wood or metal frame, you could flip them over to extend their life. But with today's specialized comfort foams and features, the majority of mattresses are meant to be used only on one side.

The all-foam Nest mattress has a Medium side and a Firm side. Clearly you have to pick one -- but it might be an interesting option for those who aren't sure which softness level they prefer, or for those who suspect their preferences might change.

We performed our standard evaluations on both sides of the mattress, and you'll see our ratings broken down below. At a high level, we found either side to be suitable for most back sleepers, but side sleepers will want to choose the Medium side while stomach sleepers will be better supported on the Firm side.

In terms of materials, the bed is composed primary of polyurethane foams, with a two-inch layer of gel memory foam on top of the Medium side. However, we didn't get much memory foam feel -- that slow, melting into the bed sensation you associate with memory foam. But overall cushioning differs depending on side. On the Medium side, our testing sunk into the mattress deeply, with a feeling of being hugged or cradled. But on the Firm side, it was the opposite -- the feeling was more 'floating on top' than sinking in deeply.

The Alexander Signature mattress excelled in our tests for motion isolation (on both sides), making it a good choice for those who are sensitive to the movements of others on the opposite side of the bed. It fell short in terms of edge support and for use on an adjustable base.

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). 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.

 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.

 

Construction

Mattress type:  Gel Memory Foam over Foam

Made In:  United States

Mattress Thickness:  13"

Mattress Weight:  65 pounds (queen size)

 

Layers

The Alexander Signature Flippable mattress is a 13″ thick mattress comprised of 5 layers. The mattress is flippable, with a different feel/softness on each side. Here, we've listed the layers with the Medium side up:

  • 1" CoolFlow quilting foam
  • 2” gel memory foam comfort layer, 3.5 lb. density
  • 2” polyurethane transition foam, 1.5 lb. density
  • 7” polyurethane foam support layer, 2 lb. density
  • 1” CoolFlow quilting foam

The Alexander Signature Flippable mattress features a quilted foam cover on both sides. Between those are three additional layers of foam, arranged for a Medium feel on one side, and a Firm feel on the other.

Nest Bedding is great about disclosing the densities of their foams; not all companies do.

Cover

The cover is made with certified organic cotton. One both sides, the cover is quilted into about an inch of foam. You get two functional handles on each side, which certainly made it easier to move and flip the bed.

 

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 Flippable mattress is sold as Medium on one side and Firm on the other - and we found that manufacturer distinction to be true for our softness scale as well. The firm side is definitely a good deal more firm than the Medium side.

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

Softness Level - Medium side
(1=Least Soft, 9=Most Soft)
5 Medium
Softness Level - Firm side
(1=Least Soft, 9=Most Soft)
3 Firm

 

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. Cushioning for the Alexander Signature Flippable mattress depends on which side you're on. The Medium side very much gave us a hugged feeling of sinking into the mattress, while the Firm side had a floating-on-top feeling. You can see the difference demonstrated below with our bowling ball, but it was even more pronounced when our tester laid on the bed.

Cushioning Depth - Medium side
(1=Shallowest, 9=Deepest)
7 Deeper than average
Cushioning Depth - Firm side
(1=Shallowest, 9=Deepest)
2 Shallow

 

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?

For the Nest Alexander Signature Flippable, it depends on what side you're on. If you are using the Medium side, you get a little memory feel from the 2" of slow-responding memory foam that's right under the quilted foam cover. It's pretty soft foam, so you sink in quickly (mattress people call this the "ride"), and because the quilted cover foam is not memory foam, the cover negates memory feel somewhat.

On the Firm side, there's no memory foam at all, so there's none of that melting feeling.

Most all-foam mattresses don't have much bounce, and the Alexander Signature Flippable was no exception. The Firm side had a tiny bit more bounce, owing to that very firm support foam being nearer the surface. But overall, this is not a bouncy mattress at all.

Memory Feel - Medium
(1=Least, 9=Most)
4 A little
Memory Feel - Firm
(1=Least, 9=Most)
2 Hardly any
Bounce
(1=Least, 9=Most)
2 Very little

 

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.

Your choice between using the Medium side or the Firm side of the mattress comes down to your preferred sleep position/s.

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 Flippable mattress from Nest.

Medium side:

Weight Range Back Sleepers Side Sleepers Stomach Sleepers
Lighter <150 lb 9 9 8
Average 150 to 200 lb 8 9 7
Above Average 200 to 250 lb 7 9 6
Heavier >250 lb 6 8 4

 

Firm side:

Weight Range Back Sleepers Side Sleepers Stomach Sleepers
Lighter <150 lb 8 5 9
Average 150 to 200 lb 9 5 9
Above Average 200 to 250 lb 9 6 9
Heavier >250 lb 9 7 9

 

Back Sleepers:

We found support for back sleepers to be good for people in most weight ranges, whether on the Medium or Firm side. We did feel the softer Medium side was better for lighter sleepers than heavier, who would be better suited on the Firm side. What we're looking for when back sleeping is for hips to sink enough into the mattress to create a neutral spinal alignment.

Side Sleepers:

In our evaluation, side sleepers should opt for the Medium side, which allowed our testers shoulders to sink into the bed and keep his spine straight. The Firm side did not have enough "give" in our tests for side sleepers except for perhaps the very heaviest individuals.

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 Medium side of the Alexander Signature Flippable mattress. However, the Firm side was a different story; those who sleep primarily on their stomachs will find excellent support with the Firm side.

 

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 Flippable mattress:

Medium side:

Weight Range Typical Curves Extra Curvy
Lighter <150 lb 9 8
Average 150 to 200 lb 9 9
Above Average 200 to 250 lb 9 8
Heavier >250 lb 8 8

 

Firm side:

Weight Range Typical Curves Extra Curvy
Lighter <150 lb 4 3
Average 150 to 200 lb 4 4
Above Average 200 to 250 lb 4 3
Heavier >250 lb 4 2

 

For side sleepers and for those who need good pressure relief, the Medium side afforded excellent pressure relief across the board, owing to its two inches of memory foam. On the firm side, you are resting mainly on the very firm support foam, and there's just not enough softness or pressure relieving material to make the Firm side a good choice.

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 Flippable 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, and we found this to be true whether on the Medium side or the Firm side.

Motion Isolation Rating
9 /10 Excellent

 

Temperature ( what’s this )

For most people, the Alexander Signature Flippable mattress will probably not feel hot. Memory foam has a reputation for heat retention, but in the case of the Alexander Signature Flippable bed, the memory foam layer is under a heavy quilted cover on the Medium side that doesn’t contain any memory material. And on the Firm side, there's no memory foam at all.

If overheating in bed is an issue for you, and you’ve experienced it with other mattresses, other types of mattresses (like hybrid or innerspring) allow for more airflow or have features that are specifically intended to address temperature.

Stays "Cool" Rating
5 /10 Okay

 

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 Flippable mattress, our tester did experience a substantial amount of dip when sitting on the edge of the mattress, but he didn't feel unstable.

Laying on the edge was worse than sitting -- on both sides -- but we were surprised that the firmer side was worse than the medium side. You can see below that the mattress bows out quite a bit and our tester felt he was leaning off quite a bit.

Edge Support Rating - Medium side
7 /10 Good
Edge Support Rating - Firm side 6 /10 Pretty good


 

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.

But for those for whom ease of repositioning is a priority, our tester did find it much easier to move about on the Firm side.

Repositioning Rating - Medium Side
6 /10 Pretty good
Repositioning Rating - Firm side 9 /10 Excellent

 

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 Flippable 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 unusual; it's become the standard for brands making beds with petroleum-based foams.

The cover is made with some organic cotton. We give all mattresses an initial 'sniff test' after unpacking, and we did think that the Alexander Signature Flippable had less of that 'new mattress smell' than most.

Green Rating
4 /10 Fair

 

Adjustable Base Compatibility ( what’s this )

We tested the Alexander Signature mattress on our standard adjustable base. Here, we are looking for whether anything weird happens, and for how well the mattress bends and conforms to the curve of the base as it is raised and lowered.

For the Signature Flippable, this mattress just did not want to conform to our base very well. The foot of the bed tended to lift up (not unusual for any new mattress) but when our tester got off the bed while in a fully articulated position, the mattress popped right up. It just didn't want to stay bent. We would expect the mattress to break in somewhat over time, but right out of the box, it wasn't good.

We also noticed that the heavily quilted mattress cover bunches up a lot in the center of the bed as the mattress is raised into position. That's something you may or may not find uncomfortable depending on how sensitive you are to it.

Overall, this Nest mattress just wasn't the best on our adjustable base.

Adjustable Base Use Rating
5 /10 Okay

 

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 13” mattress with two inches of premium gel memory foam as its comfort layer. The  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. And the mattress can be used on either side, which could be a good option for those unsure of which softness they'll prefer, or have reason to believe their preferences may change in the future.

 

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 memory foam layer on the Nest bed is of 3.5-lb. density, on the low end for memory foam, where we consider 4- and 5-lb. densities to be longer lasting. The lower support foam is a very standard 2-lb density polyurethane foam, a material that’s time-tested. If there were a red flag to us, it would be that memory foam. However the bed's lifetime warranty offsets our concerns in that area to a large degree.

 

Overall Value

In terms of value, the Nest Alexander Signature Flippable could be a good option for those who aren't sure what softness they prefer, or for those who expect their needs may change in the future. Price-wise, it does cost more than foam mattresses using similar materials. Nest Bedding does have routine sales, and our prices shown above don't include the discount extended to GoodBed readers, something that certainly makes it a better value.

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
7 /10 Good


 

Delivery, Returns, & Warranty

Delivery

  • 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.

 

Returns

  • 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

  • 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.
