BKT Patented Ergonomic Lumbar Support Cushion - Large Size (Suitable for 75-150kg)
BKT Ergonomic Lumbar Support Cushion | The Ultimate Solution for Sitting Discomfort
Specially designed for office workers, students, and long-distance drivers! Awarded the German AGR ergonomic certification and holds multiple exclusive patents. Scientifically designed to support your back, it thoroughly solves the problems of lower back pain, muscle tension, and spinal pressure caused by prolonged sitting in the same posture, allowing you to enjoy a healthy and comfortable sitting experience whether at work, at home, or in your car.
Polyol Elastic Foam Core | No Sagging After Prolonged Sitting
The core features high-density "polyol elastic foam" (density up to 37.8kg/m³), perfectly balancing softness and support. Compared to traditional sponges or overly hard materials, it adaptively conforms to the curve of your waist and hips, providing flexible and enveloping support. It has passed SGS 80,000 load impact tests, guaranteeing pressure resistance and no deformation or sagging even after prolonged sitting.
5-Zone Ergonomic Patent | Comprehensive Wrap-Around Support
Awarded the national ergonomic patent (Patent No.: ZL202121590554.3). The cushion and backrest are integrally molded and precisely divided into 5 core support zones: strong lumbar support, lateral waist wrapping, gluteal gathering and rebound, and coccyx suspension for pressure relief. It encourages and guides you to maintain an upright posture, preventing slouching and achieving perfect three-in-one support for your waist, back, and hips.
Breathable and Anti-Muggy Design | Suitable for All Seasons and the Whole Family
The seat surface is specially designed with multiple ventilation holes to promote air micro-circulation, keeping it dry and sweat-free even during prolonged use in hot summer. The product has passed strict testing by the Guangzhou Customs Technology Center, ensuring it is free of harmful substances such as formaldehyde and heavy metals, making it safe and environmentally friendly. It is perfectly compatible with office chairs, gaming chairs, dining chairs, sofas, and tatamis.
Cleaning and Usage Instructions
- Cover Cleaning: Comes with a dedicated cushion cover that can be removed and washed for daily cleanliness and hygiene. (When installing, please ensure the side with the "B" letter tag faces upwards)
- Core Maintenance: The memory foam core is strictly prohibited from water washing and direct sun exposure. For daily maintenance, simply air dry the core in a cool, ventilated place.
