GlueLess® Assembler Patents





Advantages of the GlueLess® Unit

The GlueLess® Innerspring Assembler is the first of its kind to produce an innerspring without the use of glue. The innerspring that is produced was initially independently tested and shown to have superior stability and longevity when compared to glued products.

Not only has the technology demonstrated excellent reliability with virtually no downtime, but the cost savings are significant—up to $10/innerspring by eliminating glue, reduced labor costs through automation, and lower shipping costs by reducing the weight by 5 pounds/innerspring. Modular engineering provides timely interchange of parts, and eliminating glue renders the innerspring totally recyclable. This whole process produces 25 Queen Size units an hour.

Great Feel

The welded bond is pliable and does not compromise the feel of the innerspring.

Adjustable Comfort

Changing the length of the weld can change the feel of the unit.


Temperature does not affect welded bond. (Units loaded in semi-trailer can reach temperatures that exceed 140 degrees Fahrenheit which can adversely affect hot melt glue). Temperatures below freezing make glue brittle, which can cause the units to break apart.

Lower Weight

The welded bond will reduce the unit weight.

More Permanent

The thermally welded bond is more permanent than a glue bond.


The welded bond makes a more environmentally friendly unit.

Coil diameter range from 2” to 3-1/8” (50mm – 80mm)

Patented Manufacturing Process

How do we make a superior pocket spring? Our patented system eliminates the need to turn the coil in its pocket, reducing stress on the non-woven fabric casing. It also creates a unique closing seam that eliminates the lean and false loft found in conventionally manufactured coils. The result: an exceptionally comfortable, durable pocket spring.

Custom Solutions For Your Supply Chain

At TPS, we go beyond manufacturing our exceptional pocket spring. We work closely with our valued customers to provide custom, pre-assembled mattress and furniture inner-springs that are bundled and shipped directly to the manufacturer on a just-in-time basis.

Quality Control

Our primary focus is to provide our valued customers with a quality product. Currently, we open and inspect fully 10% of the Pocket Springs that come off our line. Our Quality Control officer has the authority to stop the production at any point and make any adjustment necessary to insure the quality of our products.


TPS is committed to safety in both our work environment and our customers'. Through innovative packing and shipping techniques, our product is easy to handle without the need for tools, resulting in a smoother, safer manufacturing process.

Ultra-Efficient Production

Lowering Cost

Reducing the additional manual labor, glue, returns, shipping costs and increased efficiency returns a reduced cost for our partners and the customer.

Improving Delivery

The QuadCoil® is unique in that it can be compressed-and-rolled without compromising the integrity of the system's performance or life. This allows us to improve delivery speeds and save money!

Increased Flexibility

We are able to create any number of coil systems with varying heights, coil gauges, zoning, and more! With this increased flexibility, we can customize your coil system quickly & reliably. 


By reducing the glue, compressing the systems, and creating coil systems that last, we are able to produce some of the Earth's most eco-friendly mattress spring systems available.
