1. Construction  - Materials & Quality

One of the main considerations, when you buy a memory foam mattress, is the construction.

You need to assess the materials that have gone into making your mattress, their durability and any technology inside.

For the​ Signature ​Sleep 12 ​Inch ​Memory ​Foam ​Mattress, the innovative and unique double foam layer construction gives the product an edge over similar products in the category.

The 12​ inch mattress features a top layer of comfortable Memoir Foam which gives the mattress its luxurious feel. This layer is crucial in guaranteeing a memorable night as it also distributes your weight to the lower firmer 8 inches high-density foam

This double layer makes it possible for the mattress to provide great motion transfer as the foam conforms to your body shape and gives a comfortable experience.

The unique construction is also crucial in reducing pressure points that would naturally cause pain to a sleeper.

The use of safe, eco-friendly CertiPUR-US certified foam makes this one of the most outstanding products in this category. These foams have no flame retardants, mercury, lead and heavy metals or ingredients harmful to the ozone such as Polybrominated diphenyl ethers (PBDEs), Trisphosphate (TDCPP) or TCEP (“Tris”).

2. Firmness - Support & Feel

When buying a memory foam mattress, you want to find a product that is plush/soft sleeping but still firm for adequate body support. ​It is not easy to find this combination, but luckily, the​ ​Signature ​Sleep 12 ​inch mattress changes all this.

​With the 4​ inch, 9 ILD memory foam, you now get a memory foam mattress that is firm enough to support your back and prevent back pains.

At the same time, the high-density foam used conforms to your body to give you a cushy feeling. You feel ensconced while sleeping and this sinking feeling is one you want to get in a memory mattress.​

In simple terms, you now have a mattress that molds to the shape of your body but still offers enough resistance to support your weight when sleeping. You will wake up every morning feeling refreshed and reinvigorated.

This mattress also boasts great weight distribution which adds to its impressive feel.

Whether you use the bed alone or with a partner, you will enjoy a comfortable night because the double-layer foam offers enough resistance and absorbs all your weight.

The unique two-layer construction is great for relieving pressure on your shoulders, hips and feet

3. Motion Transfer

Motion transfer is an important point to consider when buying your memory foam mattress. ​This is more so if you plan to share the bed. ​

With th​is ​Signature ​Sleep mattress, you enjoy great motion transfer owing to the isolating qualities of this innovatively built mattress.

There is minimal or no transfer of movements from one side of the bed to the other. If your partner is a restless sleeper, you will still enjoy your sleep throughout the night.

If you plan to share your bed with a partner, the ​​Signature ​Sleep 12 ​Inch ​Memory ​Foam ​Mattress will serve you right.

4. Edge Support

Edge support is another important consideration when buying any mattress. For memory mattresses, it is one of the drawbacks because the edges lack enough strength to offer good support.

Th​is 12 memory foam mattress is no doubt a great sleeping product, but when it comes to edge support, it does not score highly. 

If you sit on the edge of this mattress, you will notice a sharp slant which means the edges are weak and can’t support your weight when sleeping. Sleeping on the edge of the mattress is thus dangerous as you might tip over.
