Specs & Features Demystified

High Breathable Material for Health

The top surface of the Amztree king size mattress is made from 3D knitted jacquard material, which is highly breathable and comfortable. This ensures the surface remains cool and dry, promoting a restful night's sleep.

CertiPUR-US & OEKO-TEX Certification

Amztree king size mattresses have passed CertiPUR-US and OEKO-TEX certifications. The materials are strictly tested and free from heavy metals and harmful chemicals, ensuring your health and safety. You can enjoy a fresh, non-odorous mattress.

Motion Isolation & Reduced Interference

The Inspring mattress uses hundreds of individually wrapped springs to provide personalized support for each person. The design reduces motion transfer, ensuring separate comfort levels for partners. This helps everyone enjoy a deeper, more restorative sleep.

Edge Support & Pressure Relief

The 12-inch king mattress features perimeter spring support, which prevents sagging or collapse. It keeps the spine curve natural, reducing pressure and providing a better sleeping posture. The spring gaps promote air circulation, reducing heat accumulation and keeping the mattress surface cool and dry, creating a more comfortable sleeping environment.
