Nolah Signature Mattress Review – Test Lab Ratings

Foam easily absorbs impact from movements. Since the Nolah Signature has an all-foam construction, it isolates motion as well as many foam models on the market. The medium surface is plush and conforms closely, resulting in a generous “body hug.” This allows the comfort layer to absorb motion fairly well and minimize transfer across the bed.

You may feel some movement when your partner gets in and out of bed or shifts positions throughout the night, especially if you are a light sleeper. However, the foam should absorb motion effectively enough to greatly reduce these types of disturbances.

Foam models are often sought after for their pressure-relieving properties, and the Nolah Signature is no exception. It is specifically crafted with AirFoam, a proprietary type of polyfoam that contours to the shape of the body and relieves pressure.

The thick layer of AirFoam in the Signature’s comfort system conforms closely to the body, resulting in a fair amount of pressure relief. This is beneficial for side sleepers, as the foam cushions the shoulders and hips while the transition layer prevents sinking in too deeply. Though polyfoam typically does not perform as well as memory foam when it comes to pressure relief, the AirFoam is engineered to provide pressure relief comparable to that of memory foam.

Most foam mattresses retain heat to some extent. Nolah crafted AirFoam to be more temperature neutral than viscoelastic memory foam. It includes microscopic air pockets that help the foam dissipate heat and regulate temperature. The cotton cover of the mattress also helps wick away moisture for added comfort.

That said, the surface conforms closely, which can restrict airflow around the body. Sleepers sink into the mattress and may feel it retains heat. The transition layer is meant to prevent excessive sinkage, which can help minimize the trapping of heat around the body.

Foam mattresses often lack edge support, as they do not have reinforced perimeters. However, the transition layer and high-density support core in the Nolah Signature provide better-than-average edge support compared to other all-foam models. Sleepers who weigh under 230 pounds are especially more likely to receive sufficient edge support.

The Nolah Signature does not provide the level of edge support offered by mattresses that are made with firmer materials. Due to the bed’s medium feel, sleepers may notice sagging on the edges when getting in and out of bed. This may be an issue especially for those who weigh more than 230 pounds, as sleepers in this weight group may not feel supported when sleeping or sitting near the edge of the bed.

Most foam mattresses lack bounce and some can restrict movement. Nolah’s AirFoam is not as restrictive as memory foam, as it returns to its original shape faster when pressure is removed. This helps when changing positions. The transition layer and higher-density foam in the support core also prevent sinking in excessively.

As with many beds, body type will affect ease of moment on this bed. Sleepers who weigh less than 130 pounds should be able to move across the bed with ease. The medium feel of the surface is most likely to inhibit movement in sleepers who weigh 130 pounds or more.

Off-gassing is to be expected with any foam mattress, and the Nolah Signature is similar in this regard to most all-foam models. Since the mattress is made with four layers of synthetic foam and is compressed and vacuum-sealed for shipment, there is an initial odor when the mattress is unboxed. However, unpleasant smells should dissipate in a matter of days.

Off-gassing is caused by volatile organic compounds (VOCs). These are not considered to be harmful, especially as the Nolah Signature is CertiPUR-US certified. This means it is low in VOCs and made without the use of harmful chemicals, formaldehyde, or heavy metals.

The initial odor of the Signature mattress should dissipate within a couple of days. Keeping the room well-ventilated will help expedite this process.
