Construction and Materials
The Nolah Signature is a 12-inch flippable all-foam mattress, built with four layers of proprietary and high-density foams.
Organic Cotton Cover
The mattress is wrapped in a GOTS-certified organic cotton cover, which is soft, breathable, and moisture-wicking. It enhances airflow and keeps the surface cool.
Comfort Layer – AirFoam™
On the softer side, the top layer features 2.5 inches of Nolah’s proprietary AirFoam™, which is designed to relieve pressure without trapping heat. It contours like memory foam but is more breathable and responsive.
Transition Layer – Deep Support Foam
Beneath the AirFoam™ is a 1.5-inch layer of high-resilience foam, which adds bounce and prevents excessive sinkage. It helps maintain spinal alignment and supports combination sleepers.
Support Core – High-Density Base Foam
The core of the mattress is a 7-inch high-density foam layer, which provides durability and stability. This layer also serves as the comfort layer when the mattress is flipped to the firmer side.
Flippable Design
The Signature is dual-sided:
Soft side (~5.5/10): Best for side sleepers and lightweight individuals.
Firm side (~7.5/10): Ideal for stomach sleepers and those who prefer a more supportive feel.
This flippable design extends the mattress’s lifespan and allows users to adjust firmness as their needs change.
Firmness and Feel
The Nolah Signature offers two firmness levels in one mattress:
Soft Side – ~5.5/10: Plush and pressure-relieving, ideal for side sleepers and those with joint pain.
Firm Side – ~7.5/10: More supportive, suitable for stomach sleepers and heavier individuals.
Side Sleepers – The soft side is a standout for side sleepers. The AirFoam™ cushions pressure points at the shoulders and hips, promoting proper spinal alignment.
Back Sleepers – Back sleepers under 230 lbs will find comfort on either side, depending on their preference for contouring or support.
Stomach Sleepers – The firm side is better suited for stomach sleepers, as it keeps the hips elevated and prevents lower back strain.
Combination Sleepers – The responsive transition foam makes it easy to switch positions. The Signature is a great choice for combination sleepers who want a soft yet supportive feel.
Cooling and Temperature Regulation
Despite being an all-foam mattress, the Signature performs well in temperature regulation:
- AirFoam™ is more breathable than traditional memory foam
- Organic cotton cover enhances airflow
- Open-cell structure in the foam promotes heat dissipation
In testing, the mattress maintained a neutral temperature throughout the night. It’s a solid choice for hot sleepers who want the contouring of foam without overheating.
Motion Isolation and Edge Support
Motion Isolation
The Signature excels in motion isolation. The dense foam layers absorb movement, making it ideal for couples who don’t want to feel each other tossing and turning. Sleep Foundation.
Edge Support
Edge support is decent for an all-foam mattress. While not as robust as hybrid models, the high-density base foam provides enough stability for sitting or sleeping near the edge.
Durability and Longevity
The Nolah Signature is built with high-quality foams and a flippable design, which extends its usable life. It’s expected to last 7–10 years with proper care. The mattress comes with a lifetime warranty, which reflects Nolah’s confidence in its construction and long-term performance.
