After I wrote my review I received an email from these guys offering me 15 % off of my next order! Really? They should be offering a full refund on the bad mat that I ordered to begin with. Or at the very least, a replacement mat. I will not be making another order from here. 15% isn't much when the middle falls out of the mat after not even 2 summers and is not safe to jump on after only one. I'll spend the 15% elsewhere and save money in the end.
