The Nest Bedding brand recognizes that each person is distinct, and with each of our unique bodies and needs, one mattress cannot perfectly suit all. Nest Bedding's Alexander Signature Mattress boasts a special feature in its flippable design, offering a different level of firmness on each side to help you find the perfect amount of pressure relief and support.

Many all-foam mattresses tend to retain heat, burdening the sleeper with an overflow of warmth, creating an unpleasant experience. However, a notable feature about the Alexander Signature is their use of the CoolFlow™ foam layer to mitigate heat issues for a cooler, more enjoyable sleep.

Below we dive into the details so you'll feel confident in knowing if the Alexander is the perfect bed for your needs or if you have no time, skip to our overall summary.

Excellent Matches For Alexander Signature

  • Warm Sleepers: This bed does a fantastic job releasing heat and creating a temperature neutral experience. Individuals who enjoy the feel of all-foam mattresses but struggle with warmth should appreciate this cooler model.

  • Affordable Luxury Shoppers: The Alexander flippable mattress exemplifies that luxury doesn't have to cost a fortune. Their innovative mattress is designed to cater to various needs with this flippable design. This bed is great for daily use and smart for a guest bedroom.

  • Combination Sleepers: Individuals who change positions often typically prefer a responsive surface. This bed's medium side provides a more contoured experience, and on the firm side, you'll feel more “on top”, for easy mobility. Both, however, offer a considerably responsive surface, great for combo sleepers.

Possible Alexander Signature Considerations:

  • Boxed Delivery: One of the perks of ordering a mattress online is that many are now being packed up conveniently in a box and delivered to your doorstep. This is enormously handy for those who don't have the time to coordinate delivery or pick up independently. However, boxed delivery does mean you have to unwrap a relatively heavy product and wait 24 – 48 hours before use.

Construction: What’s inside Alexander Signature?

At 13 inches tall, this bed is covered with an organic cotton cover, which offers a noticeably soft feel. Organic doesn't always hold significant meaning to everyone, however, the gentle texture of the organic cotton adds to the comforting experience.

Keep in mind this bed offers two firmness levels, medium, and medium-firm. Below are the details to the medium level; if you flip it, the layers will be inverted.

  • A One-Inch Plush Quilted Foam Layer offers a comforting cushion to sink into, helping relieve tension and stress and provide a relaxing experience for sleepers who enjoy a medium plush surface.
  • Two Inches of CoolFlow™ Gel Memory Foam provides a cooling layer of pressure relief for sleepers who need a soft touch for aches and pains and those who need help regulating temperature throughout the night. The CoolFlow™ foam also provides motion isolation, creating a splendid product for couples.
  • Two Inches of Transitional Polyfoam offers a firmer layer of support, aiding spinal alignment for a robust lift. Despite the support, this mattress is undoubtedly on the softer end of the firmness spectrum. However, this layer prevents heavier sleepers from excessive sinkage.
  • Seven Inches of Luxury Firm Base Foam offers strong, stable support for hip elevation.
  • 1 inch Quilted Foam on the bottom, or the top, depending on which firmness level you prefer, is a layer of soft quilted foam providing a soft layer for pressure relief..

First Impression: How Does It Feel?

The Alexander Signature Flippable mattress offers two different firmness levels, offering a product applicable to various needs. The Alexander provides considerable pressure relief with the medium preference, a standard feature for most memory foam mattresses. The plush nature of the product offers excellent contouring, making for a comfortable night's sleep.

The firmer level provides back and stomach sleepers support and lift for necessary spinal alignment, a common issue for these individuals due to their sleep posture.

Pressure Relief

If lying on the floor, you'll quickly notice where your pressure points are. Anywhere your weight gathers (often in the hip region) can create pressure, especially when you're sleeping on your side and all of your weight is settled on a more narrow surface area.

The Alexander Signature's approach to pressure relief lies primarily in the one and a half inches of quilted memory foam paired with the two inches of CoolFlow™ cooling foam, providing temperature regulation as well as soothing pressure relief. This is excellent news for side sleepers, particularly as the mattress's softer side offers tremendous cushioning without compromising spinal alignment.

The firmer side of the mattress, while advertised as medium-firm, is still a bit on the softer side. Both firmness levels tend to run a bit softer than advertised, which is terrific for those looking for pressure relief. The firmer side relieves pressure while offering a more stable surface for stomach and back sleepers.


The Alexander Signature Flippable excels in support with a variety of foam layers. Frequently foam mattresses can leave a bit to be desired in the support department, as they lack the firm design that coils often serve. However, this mattress excels in lifting the spine, offering healthy alignment on the firmer side and considerable lift paired with soothing pressure relief and contouring on the medium side.

Side sleepers should appreciate the softer side, with its exceptional contouring and gentle touch. Back, stomach, and combination sleepers should enjoy the firmer side, keeping hips raised and aligned without sacrificing comfort.

Preference-based Features

Multiple Firmness Options

By providing a Medium and Medium Firm side, this mattress makes for an excellent product if you're unsure how your needs will change over time. Having the choice also makes for a great mattress to keep in a guest bedroom. If you entertain long-term guests, the product allows you to flip the bed to accommodate varying needs easily.

The CoolFlow™ foam layer in this product regulates temperature making it an excellent choice for warmer sleepers. This material allows heat to dissipate, and its low density provides luxury pressure relief for those who need a gentle touch, along with a high response for easy movement.

Responsive Surface

Individuals who adjust positions often or struggle with mobility typically prefer beds with a bit of "push back" or bounce, which helps with movement. Sexually active couples also benefit from this feature. If you're a combination sleeper, you'll appreciate the responsive touch.

Overall Summary

Alexander Signature is a luxury foam mattress at an affordable price, and we think the firmness options will allow nearly all memory foam lovers to find their perfect firmness.

Side Sleeping Icon

Side Sleepers


Side sleepers should benefit from the medium side's dynamic memory foam layers. The CoolFlow™ foam, in particular, offers gentle contouring to the curvature waists and hips to relieve pressure points. Despite the soft nature, the bed still provides terrific spinal alignment and support.

Back Sleeping Icon

Back Sleepers


This bed offers excellent support for sleepers in this position on the medium-firm side. The combination of robust support and lift coupled with the soft memory foam top layer should allow these types to rest comfortably “on top” of the firmer side, without hips sinking out of alignment.

Stomach Sleeping Icon

Stomach Sleepers


Stomach sleepers typically need to pay attention to their spine, a mattress that is too soft can wreak havoc on back alignment because the hips can dip in this position. However, the Alexander Signature Flippable offers plenty of support on their medium-firm side, with a comfortable top foam layer for cushioning.

Combination Sleeping Icon

Combination Sleepers


This model has plenty to offer combination sleepers, regardless of whether they enjoy the softer medium feel or medium-firm option. The high responsive nature of the CoolFlow™ memory foam and high-density transition layer offers an excellent combination of gentle comfort and bounce.

Couples Icon



Couples often struggle with spatial issues and motion isolation. This flippable design excels in motion isolation however, the edge support leaves a bit to be desired. If you're looking for a mattress that lets you sleep on the edge or utilize the full surface area, the Alexander Hybrid could offer a great alternative.

Heavy Sleepers Icon

Heavy Sleepers


Heavier bodies sometimes encounter challenges when searching for a mattress to accommodate their weight. This mattress provides excellent support; however, a firmer model will likely be a better option due to the foam design and considerably soft nature. The Alexander Natural Latex Hybrid could be a great option.

Light Weight Sleepers

Light-Weight Sleepers


Lighter than average sleepers often need a softer touch, as their weight can't always activate the multiple layers of foams in a bed. This model luckily runs a bit on the soft side, offering an excellent choice for lighter bodies. The medium-soft side should provide a comfortable experience.

Overall Value


Alexander Signature packs a lot of value into their beds, and their lifetime warranty holds a lot of promise. Their flippable design allows you to change up your bed if your needs evolve, and the CoolFlow™ foam layer should provide cool, gentle night sleeps that stand the test of time.
