RV king mattresses for heavier people
Updated Oct 26, 2026 · 3 makers’ own size lists checked · findings from 7 independent testing sites · How we pick
Every mattress for heavier people we could find that’s sold in exactly 72 × 80 inches, the RV king size. Mattresses for heavier people are firmer and thicker, with stronger coils or denser foam, so they don’t sag or bottom out under more weight.
How we check: each size is checked against the maker’s own size list. Mattresses independent reviewers found supportive for people over about 230 lb, plus heavy-duty models the maker builds for heavier sleepers.
