Make your own Home Dojo Spring Floor for judo or jiujitsu

I made a spring floor at home and thought others might find this useful
if judo dojos are far away and too expensive.
My total cost was $800 which is probably 8 months of monthly fees at a dojo.

For mats and foam, shipping costs will be high and can be avoided if you find a supplier nearby, or can drive to them and pick up.

There was a link for used tournament mats at a lower price, but I do not see it now. It is 2 inch tatami
I used Zebra mats

I used Wisconsin foam.
