Where do valuable rugs actually wear out?
At the edges and under furniture. An undersized pad leaves the perimeter unsupported, so every footstep flexes the foundation against a hard floor. On an antique that is where the warp gives out.
Does the pad matter more than the cleaning schedule?
For structural life, yes. Professional cleaning addresses soil and appearance. The pad addresses abrasion, flex, and compression, which are what physically destroy a foundation.
What should go under a valuable rug?
Dense recycled felt, latex free, cut to the rug's exact dimensions. Avoid anything with a tacky backing, which can transfer to an aged foundation and cannot be reversed.
