Is the Osasuna rug soft enough for a living room?

It is a flat woven cotton rug with a pile of about 3/16 inch, so it feels firm rather than plush. Most people use it as a base layer with a rug pad or a softer rug on top.

Does it need a rug pad?

It has no backing, so a pad is recommended to keep it from sliding and to add cushioning. A pad also helps protect the floor underneath.

Can it go under a dining table?

The low pile lets chairs slide easily, and the 6 by 9 foot size fits many dining sets. Cotton stains, so wipe spills promptly.

How do I clean a cotton flat-weave rug?

Vacuum regularly on a low setting and blot spills right away. For deeper cleaning, follow the care instructions for cotton, and avoid soaking it since cotton dries slowly.

It is hand woven with no backing, so both faces are cotton, but the finished face is the one meant to show. Rotating it periodically helps even out wear.
