How to Measure for a Mattress
-
Measure the inside width and length of the bed frame, platform or opening—not the outside edges.
-
Measure the available height and clearance, especially for RV bunks, hide-a-beds and truck sleeping spaces.
-
Measure at several points because custom spaces may not be perfectly square.
-
Note any rounded corners, angled edges, cut-outs or folding requirements. A simple drawing or photo can help us confirm your custom mattress.
