Full Alexander Signature Series Mattress Review

The Alexander Signature Series Mattress is a great mattress is another quality Nest Bedding mattress to consider.

This is an all-foam mattress which softer than average, making it great for those who like to sink into their mattress as opposed to sleeping on top.

If you find that you sink too much into the mattress, simply flip it over and use the “Luxury Firm” side. This is a two-sided mattress which comes with different firmness levels on both sides. 

The price of this mattress is a little more expensive than options with foam like the Signature Sleep Contour 8, but will still remain a top option to many due to the unique features this mattress has.

What Type of Mattress is the Alexander Signature Series Mattress?

The Alexander Signature Series Mattress is made with several layers of natural and high-quality memory foam. 

Since this is an all-foam mattress, the user will sink in a lot more, on average, than a mattress which contains a coil system.

Since many people tend to complain about sinking in too much into their foam mattress, this one is also designed to flip over to the firmer side if you need the extra support. 

This is a great mattress for those who are already accustomed to the feel and design of a softer all-foam bed but still want to have a firm option ready at will. 

This mattress comes included with an Organic Cotton cover made with completely natural materials.

The interior of the mattress is exclusively constructed with different types of foam.

Two-Sided with Different Firmness on Each Side

Some people like their all-foam mattress to be relatively firm, others really love to sink into their bed as much as possible.

The good news with this mattress is that both of these people will be happy. 

Whether you want to use the Luxury Firmness side with more of a lay-on-top sort of feel, or the medium side which is softer and has more sinkage, it is entirely up to you. 

How Firm is this Mattress?

Mattresses which don’t include a coil system like this one tend to be a lot softer due to the nature of the design.

Especially if the support of the mattress is entirely made up of memory foam like this one.

Although this mattress isn’t one of the firmer options you will find, there are two potential settings for you to choose from.

One side of the mattress comes in “Luxury Firm” settings and the other in “Medium.” To change the firmness, simply flip the mattress. 

How Many Layers Does it Have?

The Alexander Signature Series Mattress comes with five total layers. If you only consider the cover as only one layer, there are four total layers. 

The interior of the mattress features a sturdier and denser strip of foam in the middle.

To create two different sides with different firmness, the layer above the interior foam layer is softer than the layer of foam below the middle layer.

When it comes to the overall comfort of the two different layers, the debate for which one better continues to rave on.

We prefer the softer side as it does a pretty good job at providing support without too much sinkage.

It is still nice, though, to switch things up for a couple of weeks and flip the mattress to experience a different type of comfort.

Especially for those who like breaking routines and trying new things.

The Alexander Signature Series Mattress has the following layers:

  1. 15 ILD CoolFlow Plush Quilting Foam & Organic Cotton Cover
  2. 10 ILD Gel Memory Foam
  3. 24 ILD Transitional Foam
  4. 30 ILD Luxury Firm Base Foam
  5. 15 ILD Coolflow Plush Quilting Foam & Organic Cotton Cover

Does the Alexander Signature Series Mattress Sleep Hot?

Typically, purchasing an all-foam mattress means that you need to sleep a little hotter than you would with a spring mattress.

Although this mattress definitely holds true and sleeps a little hotter than average, this shouldn’t be much of a concern.

The cover is designed to help hot air flow out, and you can even flip the mattress to make it sleep cooler.

The “Luxury Firm” side of the mattress tends to sleep as cool as a typical coil mattress.

In other words, being able to sleep cool with this mattress won’t be a concern.

How is Motion Transfer and Sinkage?

As with any other all-foam mattress, the level of motion transfer is very minimal with the Alexander Signature Series Mattress.

Even those who move a lot in their sleep don’t worry about waking up their partner.

The level of sinkage in this mattress is above average.

If you find that the “Luxury Firm” side isn’t soft enough, simply flip the mattress over.

The “Medium” firmness side of the mattress is softer and causes you to sink in a little bit more than on the “Luxury Firm” Side.

Does it Have any Smell?

For starters, this mattress is designed to not come included with any sort of chemical smell.

However, there might be a slight aroma that you experience for the first week of owning this mattress.

After a week or so of airing out, any sort of chemical smell that you experience with the Alexander Signature Series will go away.

Does it Require a Foundation?

When you purchase this mattress, you need to have plans for a foundation already ready to go.

The Alexander Signature Series Mattress does not come with a separate foundation or box spring.

The good news, though, is that you can choose whether or not to put it on a foundation in the first place.

Although it is always smart to put your mattress on a foundation of some sort, it is completely up to you what type to use. If any.

What Type of Cover does it Have?

Those who want to purchase a mattress which doesn’t cause harm to the environment during the manufacturing process also tend to like the Alexander Signature Series Mattress.

Made with natural organic cotton, the cover also contains CoolFlow Plush Quilting Foam.

Working together, the organic cotton and foam form an outer cover which is stronger and more protective than average. 

It’s important to keep in mind that this mattress’ cover is non-removable, making things a tad more complicated when it comes to maintenance.

What is the Best Way to Care for the Alexander Signature Series Mattress?

In order to take proper care of a foam mattress like this one, a common thing for people to do is to purchase an exterior cover. 

Since this runs the immediate risk of making the mattress sleep a bit hotter, make sure to purchase one which is designed to sleep cool. 

Those who don’t purchase an extra cover should keep sheets on the mattress at all times unless they are being cleaned.

With proper care, you shouldn’t see any signs that your mattress is worn for over a decade of consistent use.

Alexander Signature Series Mattress Mattress Durability

This mattress is designed to be both soft and durable.

The interior foam layers sit together reasonably well, with the exception of the edges of the mattress. 

The edges can wrinkle and wear quickly with misuse since this mattress doesn’t contain extra support in these parts. 

Other than this, this mattress contains materials which are higher quality than what we have come to expect in an all-foam mattress.

One of the areas where this becomes clear is when we see how long this mattress can last.

Although those that live in Alaska or Hawaii don’t qualify for free shipping, the extra cost isn’t that much in the grand scheme of things.

How Much Does the Alexander Signature Series Mattress Cost?

When we compare this mattress with some of the more affordable foam beds on the market, it is clear that product is a little more expensive than others. 

As we have tried to make clear, this is due to higher quality materials and foam which will last a long time.

Alexander Signature Series Mattress Review – Our Verdict

Overall, this is a high-quality mattress which you should consider if you have high expectations and want an all-foam mattress which is both soft and cool. 

This mattress contains a foam cover which is designed to allow hot air out of the mattress, which helps you to sink into the mattress without worrying about getting too sweaty.

If you want an all-foam mattress but are concerned with potentially sinking too much into the foam, you will be glad to know that there is a firmer “Luxury Firm” side. 

The other side of the mattress is softer and tends to sink more. Due to the interior design of the mattress, one side of the mattress is firmer than the other side.

Since this mattress is made with high-quality and durable materials right here in the USA, the price ($1,449 for a Queen) is a good deal.
