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.
Please Note :
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.
