Knots per square inch (KPSI)
When it comes to picking textured rugs, there is more to it than just picking a rug that has a fluffy surface. Different textures mean different things, and can tell you about the pricing, function, durability and maintenance of the rug.
The pile of a rug refers to the way the fibres are finished. These are either trimmed or untrimmed (or sometimes a combination of the two) to create an array of visual and textural effects on a rug.
