How this bed is put together

The materials, described by King Koil in their own words.

iCool™ Sense Fabric

iCool™ Sense Fabric – Instantly Cool Fabric with Advanced Ventilation Technology

iCool™ Sense Fabric is an innovative mattress cover designed to enhance your sleep to be even cooler. It uses high-tech fibers with a structure that allows air to circulate freely throughout the night.

iCool™ Gel Memory Foam

iCool™ – King Koil’s exclusive for a deeper, cooler sleep

iCool™ is a memory foam technology developed by King Koil specifically to elevate your rest beyond ordinary mattresses. The process involves integrating special Cool Gel particles directly into the foam structure, which helps absorb and distribute body heat continuously as soon as you lie down.

X5CoilTech™ Spring 5 Zones

X5 Coil Tech is a 5-zone independent spring system designed according to ergonomic principles to support the body in balance in each important position: head, shoulders, back, hips, and legs.

Caregenic™ Technology

Caregenic™ is a sleep health technology that SleepCity offers as a standard with every mattress in the showroom, whether it’s Dreammaster or King Koil. You can be sure that every selection from SleepCity starts from the cleanest and safest foundation. This technology works by permanently embedding antibacterial and anti-dust mite agents (Anti-Dust Mite) into the fabric and materials. It doesn’t just coat the outside surface, but also penetrates deep into the mattress structure to inhibit the growth of germs, reduce the accumulation of bacteria, dust, moisture and dust mites, which are often the cause of bad odor or allergies. This technology is designed to be safe for the skin, even for those with sensitive skin, young children or the elderly, so you can sleep confidently every night without worrying about irritation or long-term health. Every touch you get from a SleepCity mattress is not just soft and comfortable, but also has a silent protection that is invisible… but felt.
