Unique Selling Point (USP)

Best low price mattress offering pressure relief and motion isolation

Some users might find it on the firmer side and some say it is plush. But one needs to understand the dynamics associated with a memory foam mattress.

Any memory foam mattress looks firm initially. But when you sleep on it for few minutes, you will notice that it slowly turns plush around critical points like shoulders and hip. That’s how the top layer of a memory foam mattress reacts to body heat.

But you should be aware that no matter how plush you might feel around critical points but you are not going to sink deep into the mattress that you would develop aches the next morning. In fact pressure/pain relief is the unique selling point (USP) of Signature Sleep 12 inch mattress.

In Signature Sleep mattress, the top layer foam conforms to your body shape to offer that ultimate comfort you expect from a memory foam mattress. And the base layer relieves pressure/pain around hip and shoulders by preventing you from sinking further down.

Signature Sleep Memoir 12 inch Memory Foam Mattress Review


Signature Sleep has a fairly simple two layer construction although this one is a 12 inch size mattress.

  • Top layer: 3.5 inches comfort memory foam
  • Base layer: 8.5 inches high density foam
  • Cover: Made from well knit breathable fabric

3.5 Inch Comfort Memory Foam 

The thicker this layer, the higher the comfort level

3.5 inch thick comfort layer is really on the higher side as other 12 inch mattresses have, at the maximum, just 2.5 inch thick comfort layer.

Initially, when you lie on the mattress it might carry a firm feel but after few minutes you will notice that the layer slowly starts conforming to your body shape, hugs you around critical pressure points. And this when you would really start experiencing the ultimate comfort associated with sleeping on a memory foam mattress. That’s the beauty of comfort foam.

8.5 inch High Density Foam Base Layer

High density foams have very closed cell structure and this makes the base layer quite firm in feel. And all memory mattresses embed high density foam as base layer. The only thing that varies is the thickness of the layer.

In this Signature Sleep 12 inch version, the base layer is really massive. It is 8.5 inch thick and there is absolutely no chance of the mattress bottoming out. Perhaps, this is why the 12 inch version of Signature Sleep is famous for pressure relief around critical points. No matter how hard you try pushing yourself down, but the 8.5 inch thick layer would surely prevent you from sinking deep into the mattress.

The thicker this layer, the higher the support and pressure/pain relief

Comfort & Pressure Relief

The sink that you might feel while lying on the mattress is mainly due to the top layer aligning with your body curvature but it’s not exactly that damaging sink that few might think. It is only the comfort and body conformation.

12 inch mattress with 3.5 inches top layer means it offers top notch comfort. It is designed to best suit both light weight as well as above average weight people.

If you sink for more than 3.5 inches and into the base layer as well, then you can surely say that the mattress is too plush. However, if your sink is well within 3.5 inches then that is absolutely normal and you really need not worry thinking that your mattress might be on the plush side.

And this is why some people think that the mattress is plush while others feel it is firm. As mentioned in the introduction, one needs to understand the dynamics and working style of memory foam mattresses. The top layer is always plush, the intermediary layers are medium firm while the base layer is always firm as they are made from high density foam.

Pressure Relief

Around critical pressure points like shoulders and hip, the foam quietly aligns with your body curvature offering you the comfort and soft cushion like feel while distributing the weight equally across the sleeping surface. In case of light weight people, the top layer might sink and align by 1 inch while for people on the heavier side it might sink up to 2 or 2.5 inches.

With the base layer is 8.5 inches in thickness, the mattress offers ultimate pressure relief, be it for side sleepers, back sleepers or stomach sleepers.

Motion Isolation

It is not fair to expect motion isolation feature from budget mattresses. But Signature Sleep although has a simple 2 layer construction is perhaps the only low price mattress that offers motion isolation.

CertiPUR-US Certification

Even though the mattress is made in China but the memory foam used in making this mattress is CertiPUR-US certified thus meeting all US safety regulations. It is environment friendly, free from free of ozone depleters, PBDEs, flame retardants, lead and heavy metals.

Shipping & Inflation Time

The mattress comes compressed, rolled and vacuum sealed in a single box. The mattress should be ready to use anywhere between 24 to 48 hours.

Although the mattress expands to its full size well within few hours but it is always advised to wait for 24 to 48 hours for it properly expand in every corner plus the typical yet mild new foam smell to disappear.


Never believe if someone tells you that low price mattress are also low on performance. That’s never the case at least with both Signature Sleep 12 inch version and Best Price mattress 10 inch version.

These two memory foam mattresses are low on price yet high on performance. Signature Sleep, especially is best budget mattress when it comes to offering comfort, pressure relief and motion isolation at relatively low cost.

Signature Sleep has 4+ rating drawn from 8000+ reviews on Amazon. The numbers speak for themselves.
