On the market, we often see these words: 3-zone, 5-zone, 7-zone, 9-zone spring mattresses, 7-zone latex mattresses, etc. What do these mean? What is a mattress partition? Below we will explain to you.
Mattress partitioning refers to the process of designing a mattress by dividing it into different areas based on the different focal points where people sleep on the mattress. Make corresponding designs for different areas to make the softness and hardness of the mattress more suitable for human sleep requirements.

Common partitions include:
Zone 1 Head and Neck Zone
Zone 1 provides a suitable level of stability for the head and neck to help prevent muscle tension and pain in the neck.
Zone 2 Shoulder and Upper Back Zone
Due to the fact that the shoulder is the widest part of the human body, it requires more "giving" than the buttocks and lower back. A hard mattress prevents the shoulders from fitting against the mattress, resulting in compressive needle pain and circulation problems. This area provides the necessary softness to the shoulders, making them feel even more comfortable. Two crescent shaped pressure relief channels cross the entire shoulder and back area, providing stronger elasticity during lateral sleep. Whether lying down or sleeping on one side, this 7-zone mattress has the effect of relaxing pressure, relieving acupuncture, and correcting the spine.
Zone 3 Lumbar Zone
This extremely important area is essential for the comfort of the lower back. It has the most stable characteristics to provide support for the natural curves of the back, prevent spinal sagging, and thus alleviate tension and lower back pain. Usually, 40% of the weight of the human body is compressed in the middle. If there is no additional stability in the lumbar region, a soft mattress will trap the spine in a hammock like bending state due to the inherent nature of gravity, causing muscles to become stiff and painful due to stretching and tension.
Zone 4 Pelvic Zone
A hard mattress can cause the buttocks to rest on the surface of the mattress, causing the lower spine to fall into an uncomfortable, downward curved position. A softer and more elastic pelvic area can fit the hips against the mattress, thereby relieving pressure and adjusting the spine correctly.

Zone 5 Knee Zone
This area has the same stability as the lumbar region. Latex has natural softness properties, so it can provide appropriate support for the knees, prevent allergies and fires.
Zone 6 Lower Leg Zone
This area has the same stability and pressure relief channels as the shoulder and back areas. It provides soft and smooth support for the calves, providing comfort and pressure relief for the feet and ankles when bending the knees.
Zone 7 Foot and Ankle Zone
Similar to the head and neck area, the soft and smooth ankle area provides comfort and pressure relief for your feet and ankles.

The nine zones are further subdivided into: head and neck, shoulders, back, lumbar spine, pelvis, thighs, knees, calves, ankles and other areas.
Xiyatu has a nine zone spine protection sleep system as one of the core patented technologies. Based on ergonomic principles, it uses different load-bearing and pressure data from nine different positions of the human body, including the head, neck, shoulder, back, waist, buttocks, thighs, calves, and feet, and uses various spring engineering techniques with different parameters to create a nine zone spine protection sleep system, providing perfect support for your body and allowing you to experience a cloud like comfortable sleep experience.
