Continuous Coil 拉丝提丝/一线弹簧
An Innerspring Mattress coil design wherein each row of Coils is constructed from a single wire shaped into a series of S-shaped ringlets. The concept behind this design is that by attaching each coil to its neighbors, the Innerspring Unit will have improved strength, stability, and Durability. See our Coil Guide to learn more about the various types of mattress coils and how to compare them.

Offset Coil 开口弹簧
Type of Innerspring Mattress Coil that has an hourglass shape similar to a Bonnell Coil, but with flattened edges at the top and the bottom of the coil to create better hinging action. Relative to Bonnell coils, Offset coils conform more to your body, make less noise, and are typically found in more expensive mattresses.

Prorated Warranty 有限质保
Mattress Warranty that does not cover the full mattress purchase price or replacement value after a certain period of time, requiring the customer to pay a portion of the original price to have it replaced, typically depending on how long the mattress was used.
Quilting 间棉层
The top-most layer of padding inside the mattress, consisting of Foam and/or Fibers stitched to the underside of the Ticking. Can provide additional Comfort, as well as a way for the mattress to breathe, and may also include a separate layer of padding such as a Pillow-Top or Euro-Top. Also refers to the process by which the quilting layer is stitched to the ticking and other padding layers of the mattress.

Can also encompass other attributes such as the degree to which the mattress conforms to your body. See our Support Guide to determine the best level of support for you.
Synthetic Latex 人造乳胶
Type of Latex that shares many of the same physical properties as Natural Latex, but is made through a chemical process using petroleum-based materials. Generally considered slightly stiffer than natural latex, but also more consistent in quality, giving it slightly better Resiliency over a very long period of time.
Tack and Jump Quilting 跳针间棉
Quilting process that uses hundreds of needles but is not limited to a continuous pattern, allowing for more Loft and a softer-feeling surface. Typically found in more expensive mattresses.
Tape Edge 边带
The cord-like seam that runs along the edges of the mattress surface.
Tempering 回火/热处理
Process by which Coils are treated to ensure that they return to their original shape and height after compression, improving their Durability and Resiliency. In the tempering process, coils are heated (or electrified) and then cooled, realigning the molecules in such a way that enhances the coil's strength and resistance to Sagging. Also referred to as stress relief. See our Coil Guide to learn more about coil construction and what to look for in mattress coils.
Ticking棉布层/最外层
