Our replacement jumping mats proudly use a grade #1 black non-abrasive Permatron® type mat material and are constructed using only the finest heavy-duty thread and rust-less hardware connection v-rings available for added mat life. Measure your frame from one side to the other side. This is your frame size. Measure your old mat from edge to edge, not including v-rings. This is your mat size. Measure one of your springs, including both hooks. This is your spring length. Now, count all the springs holes in the frame and see if it matches the number of v-rings on the mat and number of springs you have for your trampoline. This is your spring count. REMEMBER: Measure & Count twice so you only have to order ONCE!
How to Measure for an Octagon Trampoline Mat
Measure the frame. You will measure the frame from outside frame to outside frame straight across from point to point, as shown in the diagram below. This will give you your frame measurement. To check your accuracy, you can measure from flat to flat straight across the middle, there should be about a foot difference between the two measurements. The point to point measurement will give you your frame size which you will then use to choose the correct mat.
Measure the springs. You will take a spring OFF the trampoline, make sure that it is fully recoiled and measure it from hook-end to hook-end. It is very important that you not use a stretched-out spring and that the spring NOT be attached to the trampoline to get an accurate measurement.
Count the springs. You will count the spring holes around the top of the trampoline frame. We suggest that you also count your springs to make sure that none are missing.
Measure the mat. If possible, it is best to measure the mat while still attached to the frame. You will measure the mat from hem to hem straight across from point to point as shown in the diagram to the right, DO NOT INCLUDE THE V-RINGS. Note the exact inches of the measurement.
