LianRou Technology attend the Fair of Furniture China 2025 in Shanghai

Even during the peak season of September, the summer heat persists. On September 10th, the Shanghai New International Expo Center hosted the grand opening of the 30th Furniture China Exhibition. Exhibitor Lianrou Technology's booth N8A01 was bustling with activity. This time, Lianrou Technology continued to innovate its high-tech pocket spring unit solutions, delivering unprecedented impact, expanding new horizons, and creating fresh business opportunities for industry professionals.

Lianrou Technology specializes in advanced research and development, as well as the exclusive manufacturing of specialized high-tech pocket spring units, committed to providing "light intelligent manufacturing" solutions for healthy sleep within the upholstered furniture sector. The exhibition showcased over 30 innovative high-tech furniture spring unit products. Notably, new derivatives of glue-free four-leaf clover designs made a striking debut, alongside the innovative "cotton box spring pad" material. The moisture-wicking, breathable cotton series of bed nets attracted continuous visitor engagement. Electric bed herringbone springs gained significant popularity, and mattress spring unit traceability technology drew considerable attention.

Eco-friendly, glue-free mattress manufacturing solutions

Lianrou's glue-free four-leaf clover spring unit and mini four-leaf clover spirng unit (minimum height of 4 cm) meet the production requirements of various soft furnishings, including mattress cores, pillow cores, sofa cushions, backrests, and automotive seat cushions. At this event, Lianrou introduced three kinds of new glue-free pocket spring units, all manufactured without adhesives, complying with environmental standards in the US, Japan, and Europe.

Edge-Threaded Glue-Free Cotton Fabric Pocket Spring Unit

These cotton fabric pocket spring units utilize sewing techniques instead of ultrasonic welding, with spring bars assembled through threading. Lianrou's cotton spring manufacturing machinery employs advanced mechanical sewing technology, resulting in fine, durable stitches that rival hand-sewn quality. The breathable cotton fabric ensures moisture management, enhancing durability compared to non-woven alternatives.

Glue-free Woven Fabric Pocket Spring Unit

A derivative of the glueless four-leaf clover design, the Glue-free Woven Fabric Pocket Spring Unit maintains the iconic four-leaf shape and is assembled using fully ultrasonic welding technology. It features independent spring support and uniform force distribution, resulting in a more stable core structure than heat-welded alternatives. The woven fabric offers a premium tactile experience—crisp, comfortable, durable, and aesthetically refined—culminating in a high-quality bed net.

Woven Fabric Box Pocket Spring Unit

Woven Fabric Box Pocket Spring Units serve as premium comfort layers for mattresses and cushions. The high toughness and deformation resistance of woven fabric provide superior pressure distribution, delivering unique cushioning support and enhanced comfort. The springs operate independently within the fabric pockets, reducing friction and noise for a quieter sleep experience.

Mattress Pocket Spring Units traceability technology

Lianrou also showcased innovative labeling technology, enabling bed cores to be branded with product names or logos, while also facilitating production tracking via QR codes. Each pocket spring unit is assigned a unique QR code that, when scanned via a dedicated app, reveals detailed information such as spring specifications, production date, fabric weight, and company data. Customizable information options further assist upholstered furniture suppliers in strengthening brand identity and enhancing after-sales service.
