Nest Bedding Alexander Signature Series Mattress Review
Alexander Signature Series Flippable
The Alexander Signature Series Flippable is a mattress that offers two different sleeping surfaces on each side, making it one of the more adaptable mattresses that Nest Bedding offers.
On one side, the firmness level is medium (5), while the other side is firm (7). Both sides, however, are wrapped in an organic knit cotton cover, which is soft and breathable to keep you cool at night. The mattress contains a layer of gel-infused memory foam certified by CertiPUR-US, as well as CoolFlow foam that’s designed to dispel body heat.
When it comes to size options, the mattress is available in queen, twin, twinXL, full, king, and California king. Below, we’ve compiled some stats on how the Signature Series compares with some of Nest Bedding’s other mattresses, including the Signature Hybrid and the All Latex.

Nest Bedding Alexander Signature Series Mattress Review: Our Verdict
With its flippable construction as its most notable feature, the versatility of the Alexander Signature Series is where it shines. Whether you’re a combination sleeper who enjoys the options, unsure of what level of firmness is best for you, or looking for a guest bedroom mattress that can appeal to different types of sleepers, the Signature Series covers more bases than a single-surface mattress.
In most other areas, the mattress proves satisfactory, but not exceptional. Because of the thick memory foam comfort layer on the medium side, couples might appreciate the lack of motion transfer, but be turned off by the lack of bounce and edge support, which, respectively, hinders sex and limits the usability of the bed.
While sleepers of most sizes and preferred sleep positions are likely to find at least one of the sides serviceable, the mattress performs best with those under 130 pounds. This is because the medium side’s firmness combined with the all-foam construction is soft enough for preventing pressure points, while still firm enough to keep the spine aligned.
Choose the Alexander Signature Series if…
- Your firmness preferences fluctuate from night to night
- You’re unsure if a medium or firm mattress would be best for you
- You weigh less than 130 pounds and prefer a medium firmness
- You’re a side sleeper
Keep Shopping if…
- You’re solely interested in either a medium or firm mattress
- You want a mattress designed to stay cool
- You’re especially sensitive to out-of-the-box new mattress odors

How Does the Alexander Signature Series Mattress Feel?
Being flippable, the Alexander Signature Series offers two distinct feels, though each side shares a soft cotton cover and a layer of quilting foam. This top layer provides an immediate softness and breathability to both sides.
Since the mattress is completely foam and doesn’t contain springs, there isn’t a feeling of bounciness. Instead, you can expect the bed to hug your body and contour around it. By doing so, the bed can provide greater pressure relief than an innerspring mattress.
Naturally, the medium side will be the softer of the two, as it has gel memory foam beneath the quilting foam and a 2-inch transitional polyfoam layer. The firm side lacks the gel memory foam layer, making it less soft but more supportive.
What Is the Alexander Signature Series Mattress Made of?
Both sides of the Alexander Signature Series feature an organic cotton cover. On the inside, however, each side of the mattress features its own foam comfort layers that provide a unique firmness level and feel.
The Signature Series has a completely organic cotton cover. Cotton is a soft and breathable material. The breathability helps to prevent moisture buildup and maintain a cool surface. The cover is unable to be removed for cleaning, however.
Both sides of the mattress have a comfort layer of CoolFlow plush quilting foam, which is intended to help prevent the buildup of body heat. The softer side has an extra comfort layer, however, in the form of gel memory foam, which is designed to prevent heat buildup. It also provides pressure relief by contouring closely to the body.
The medium side features a polyfoam transitional layer that’s meant to provide an additional buffer between the sleeper and the mattress’ support core.
The support core of the Signature Series is 7 inches of high-density base foam. The firm side is more influenced by the support core, as there’s only 1 inch of comfort foam between it and the sleeper, which contributes to its firmness.
What Type of Sleeper Is the Alexander Signature Series Mattress Best for?
The Alexander Signature Series caters to a wider variety of sleepers than normal, thanks to its two sides. While side sleepers aren’t likely to enjoy the firm side, the medium (6) side provides more of the cushioning they require.
Back and stomach sleepers, on the other hand, will likely prefer the firm side, considering that a firmer surface prevents the abdomen from sinking too much and causing strain on the back.
Since sleeping on your side applies more pressure on your shoulder and hips, a medium to medium firm mattress that allows for a lot of contouring is ideal. Therefore, the medium side of the Signature Series would be most appealing to a side sleeper – especially those who weigh 230 pounds or less.
Due to the medium and firm sides of the mattress, most sleepers who alternate between their backs, stomachs, and sides are most likely to prefer the medium side, given its middle-of-the-road firmness. Combination sleepers over 230 pounds, however, will likely prefer the firm side and its more robust support.
It’s important for back sleepers to receive proper lumbar support, which means they shouldn’t sleep on a mattress that’s too soft. However, a mattress that’s too firm won’t provide proper cushioning for the lumbar area. Therefore, both sides of the Signature Series are likely to keep back sleepers satisfied, with lighter sleepers preferring the medium side and heavier sleepers generally preferring the firm side.
Much like back sleepers, stomach sleepers are in need of proper lumbar support and cushioning, but are more likely to prefer the firm side. This is because stomach sleepers are more prone to sinkage around the midsection, where most people tend to carry more weight, and so they often need extra support. All-foam construction isn’t ideal for stomach sleepers, as hybrid mattresses tend to provide stronger support for preventing hips from sinking too far into the mattress.
How Does Body Weight Impact the Alexander Signature Series Mattress' Performance?
A sleeper’s weight has a lot to do with how a mattress will feel for them. Those over 230 pounds are less likely to feel comfortable on a soft mattress, due since they need more support to keep their spines properly aligned. Those under 130 pounds are more likely to experience pressure points on a firm mattress.
Due to the dual nature of the Signature Series, its comfort ratings vary. While it comes up as good or fair for most weights and sleeper types, there are some exceptions worth noting.
Those under 130 pounds are likely to prefer the medium side, since its thick comfort system provides ample cushioning to prevent pressure buildup in areas such as the hips and shoulders.
The only area where the mattress comes up short is with side sleepers under 130 pounds on the firm side. Since these types of sleepers don’t sink as much and the surface is firm, the pressure on their shoulders and hips will likely result in an uncomfortable sleep.
Is It Good for Couples?
Overall, the Alexander Signature Series should be a decent mattress for couples. Its memory foam comfort layer on the medium side prevents motion transfer, so there’s less worry of couples waking each other up, though this isn’t the case for those who choose to use the firm side.
With the cotton cover and the CoolFlow layer of foam, the mattress should do a fair job of regulating temperature. For couples that value temperature regulation above all else, it would be better to get a hybrid mattress, as they are more conducive to airflow than all-foam models. Nest Bedding’s Organic All Latex Mattress is particularly good for keeping cool at night.
On the downside, the lack of edge support on the medium side means there’s less sleeping space for two people. On the firm side, this isn’t as much of an issue.
