No attached backing
Flatwoven and hand-knotted rugs have no separate backing layer. Nothing to delaminate, nothing to off-gas, and safe on finished wood with a proper pad.
Latex adhesive (tufted rugs)
Hand-tufted and machine-tufted rugs glue the pile to a scrim. The adhesive is the source of new-rug odor and eventually dries out and sheds.

Common in cheap washable rugs. It compresses permanently, can yellow, and often separates from the pile after several washes.
PVC and solid rubber
Grippy but capable of reacting with floor finishes over time. Use a felt-and-natural-rubber pad instead.
