Litoscope Recalculates the Mattress Industry
A French mattress guide that extracts product-sheet data and publishes comparisons based on cost per night, price per centimetre, and inferred density.
Field notes
Litoscope separates product-sheet transcription from interpretation: each recorded claim is dated, while derived figures are accompanied by a formula and sample size. Its stated metrics include price per centimetre and density inferred from weight and volume, with absent values left as “n.c.” The homepage lists 15 comparisons and three calculations per comparison, alongside tools for bedding height, product-sheet decoding, and cost per night. It also explicitly disclaims physical mattress testing and medical advice.
