A glueless pocket spring is a type of pocket spring used in mattresses and upholstery that is assembled without the use of glue or adhesives. Instead, the springs are connected using mechanical or thermal bonding methods, such as ultrasonic welding or fabric sleeves.

Key Features of Glueless Pocket Springs:

1. No Chemical Adhesives – Unlike traditional pocket springs that may use glue to hold the springs together, glueless pocket springs rely on physical bonding techniques, making them more eco-friendly and reducing off-gassing.

2. Better Durability – Since glue can degrade over time, glueless systems often last longer without sagging or separation.

3. Improved Breathability – Without glue blocking airflow between springs, glueless pocket springs typically offer better ventilation, keeping the mattress cooler.

4. Hypoallergenic & Healthier – The absence of glue reduces potential allergens and harmful VOCs (volatile organic compounds), making it a healthier choice for sensitive sleepers.

5. Individual Spring Movement – Like traditional pocket springs, each coil moves independently, providing targeted support and motion isolation, which is great for couples.

Common Bonding Methods for Glueless Pocket Springs:

• Ultrasonic Welding – High-frequency sound waves fuse the fabric pockets together.

• Heat Bonding – Thermal techniques melt fabric layers to secure springs.

• Fabric Sleeve Interlocking – Springs are stitched or mechanically locked into fabric pockets.

• Benefits Over Traditional Glued Pocket Springs:

  ✔ More environmentally friendly
  ✔ Longer-lasting structure
  ✔ Better temperature regulation
  ✔ Reduced risk of allergic reactions

  Glueless pocket springs are often found in premium mattresses that emphasize sustainability, durability, and health-conscious materials.
