If your old mat is available and has no holes over 4-inches long, we prefer to receive your mat measurements. Please go to mat measuring instructions.

Collecting these measurements requires two people.

Hold the measuring tape tight. Do not let the tape sag.

Do not lean against the frame while measuring.

When measuring frame, measure to and from where the spring hooks the frame. Usually springs hook into spring holes drilled into the frame, but some frames have pieces of zig-zag wire welded to the inside edge of the frame. Regardless, measure to and from where the spring hooks the frame.

Normal - Springs butt up on each side of corner. This is the most common corner configuration.

Normal with Diagonal - In addition to the springs on each side of the corner, there is an extra spring mounted diagonally. These extra corner springs are typically longer than other springs.

Diagonal Only - Each corner has only a diagonal spring with no additional springs on each side of the corner. These corner springs are typically longer than other springs.
