If your old mat is available and can be measured without spanning a hole, we prefer to receive your mat measurements. Please go to mat measuring instructions.
Please Note :
Collecting frame 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.
