Yes, the answer could be just to count them… But hey, simple task can reveal themselves tricky sometimes. You may have loose the mat and disassembled your frame.
To count your spring, you should use both methods bellow to double check your result:
- Count the number of triangle on your old mat.
One easy way is to fold the mat in two so that you count only half of it.
- Count the spring holes in the framework.
One easy way is to count only the slot in one tube and multiple by the number of tube (the number of tube frame is always double the number of W shape leg base).
Your result should be a multiple of 8. Sometimes, it’s only a multiple of 4.
