Download TimberLab and open Queen platform bed in the catalog to get every cut length and end-cut angle, all 6 assembly steps in 3D, and Timbo, the AI build helper. Catalog plans are free to open; some features, such as AI edits, require a subscription.
Check that your mattress fits the frame before you cut the slats, and follow your mattress maker’s slat spacing guidance. The rail-to-post joints carry the load, so fasten them with structural screws or bolts and glue.
