Flat weave rugs are easy to move. Not having a pile means that flat weave rugs use substantially less material, so they are lighter than other types of rugs.
The weave style means the rug tips are not constantly being crushed underfoot. While the rug can certainly wear over time, it will not develop flat areas or paths like you might see in loop pile or cut pile rugs.
Flat weave rugs are reversible and are easier to clean than many other oriental rugs.
