Where the cost change comes from

Mattresses

What the latest data shows: input costs for mattresses rose 1.1% over the 3 months to August 2026; general prices rose 0.8% over the same time. The biggest item is foam and plastics.

On a €1,000 item, the same change in costs is about €11; the change in general prices is about €8.

Corrected on October 21, 2026: the general-prices figure now covers the same 3 months as the cost figure, to August 2026; it was shown for the 3 months to September 2026.
