# Mattress firmness and pillow loft recommendations

All 32 combinations of sleep position, body-weight band, and sleeping temperature, with the firmness and pillow-loft target for each. Firmness is a range out of 10 where 1 is softest and 10 is firmest. Pillow loft is the pillow's height in centimetres under a loaded head.

Firmness has no industry standard — no ASTM or ISO specification exists, and each brand sets its own scale — so every value here is a recommendation target expressed as a range, never a point value to match against a product label.

The rule of thumb behind the table: side sleepers need a softer surface so the shoulder and hip can sink enough to keep the spine level, stomach sleepers need a firmer one so the hips do not sag, and heavier sleepers need more firmness to get the same effective support because they compress the comfort layer further.
