Your body hasn't decided yet.

ZONE-1
Most people evaluate a mattress within seconds.
But the body's true response reveals itself not in seconds, but in minutes.
Sleep Is Not a Product
It Is Nervous System Architecture.

How does the brain
test a mattress?

In the first 15 minutes, the nervous system:
Pressure Points

Detects
pressure points

Spinal Alignment

Checks
spinal alignment

Deep Sleep

Decides whether to trust
the surface and enter
deep sleep

This process doesn't happen in seconds — it occurs through the nervous system's adaptation.

That's why the real difference can only be understood through experience.

BAD HABITS

"You're testing the mattress wrong."

You try it for 20 seconds

You decide under store lighting

You don't wait for your body to adapt.

That's why many mattresses feel good at first…

but your body never truly adapts.

QUAREST SLEEP TECHNOLOGIES

Ideal Mattress System™

One structure.
A single system that adapts to different bodies.

4 different models.
The same nervous system architecture.

This structure shows the common system architecture of all models.

The first four layers are shared across all models.

Q7 Hybrid

Quarest's Unique Design

With the Quarest Luxe Touch™ washable cover and Skin+™ cell renewal technology, it offers a refreshing, hygienic sleep.

Adaptive Flex™ (Personalized Feel) technology provides maximum pressure distribution and extra lumbar-hip support.

The Qua Double Rest™ spring system and High Rest™ layer deliver perfect spinal support and long-lasting comfort for all body types.

Quarest Luxe Touch
With Skin Plus™

Quarest's exclusive design featuring an ultra-soft touch, wash-resistant fabric structure, YKK zipper detail, and the patented Skin+™ cell renewal technology in a washable cover system.

Note: Skin+ technology has been proven through test results to be absorbed by the body even through sheets or nightwear, up to 20 washes at 40°C.

3D Spacer Core Lining™ Layer

3D Spacer Core technology is an innovative solution that allows the mattress to be used comfortably even when the outer cover is being washed. In traditional mattresses, thin and non-functional inner covers cause the mattress to lose its supportive structure when the outer cover is removed. Additionally, air channels close, preventing the mattress from breathing and maintaining temperature balance. However, 3D Spacer technology eliminates this problem, allowing you to sleep comfortably on the mattress even while the outer cover is being washed. The inner cover's special design offers maximum air circulation, maintaining temperature balance and preventing overheating.

Airflex Zone™ Layer

The Airflex™ layer is equipped with the latest technology featuring a 7-zone supported, regionally ventilated filling system. This design is engineered to provide maximum pressure distribution in every sleeping position and for every body type. The fundamental purpose is to offer balanced support and comfort at every point, supporting the body ideally.

Quarest® Foam™ Layer

AdaptiveFlex™ Technology

The Quarest® Foam layer is a first in Turkey, featuring a 3-zone memory foam structure with regional ventilation holes and varying densities on the same surface. This innovative technology combines the sleep experience with personalized comfort in every sleeping position, offering a unique solution for individuals with high body mass index. The 3 different zones in the mattress layer are optimized in density and support levels according to the body's needs. It provides extra support especially for the lumbar and hip area, relieving pressure and perfectly conforming to body contours.

A revolution in comfort with Quarest®! Quarest's engineering marvel AdaptiveFlex™ offers personalized feel through the unique harmony of Airflex Zone and Quarest Foam™ technologies. Experience ideal comfort on the same surface in every sleeping position and body type. One mattress, limitless adaptation!

High Rest™ Layer

The High Rest layer is an innovative layer that combines high comfort lifespan with durability, thanks to its variable cell structure and excellent elasticity and resilience. It offers a comfort lifespan experience that will last for years in your mattress, even for individuals with high body mass or couples with contrasting body profiles.

5,000+ night comfort lifespan guarantee
(Increases average comfort lifespan by approximately 20% with its strong resilience and special comfort structure)

Qua Double Rest™ Pocket

The Qua Double Rest™ Pocket spring system is a spring technology designed exclusively for Q7 models, different from traditional 7-zone pocket spring systems. This smart spring system has been developed by reducing spring diameters and increasing the spring density per square meter. Thus, it provides both more support and higher comfort, delivering a sleep experience suitable for every body type.

Over 1,300 smart springs in an average double mattress, with high durability that extends comfort lifespan!
