Planning boundary

Useful geometry, not a purchase guarantee.

Results use the values you enter and the source-backed nominal mattress records in this site. Finished products, frames, elastic construction, room obstructions, and manufacturer tolerances can change real-world fit.

Bedroom layouts are planning guidance, not building-code, accessibility, fire-safety, or professional design determinations.
