Bests & Worsts Reviews from Amazon

Bought Oct 1. Delivered Oct 4. Noticed this split today. I have sat on the ball a handful of times and the seam is splitting? I weigh 210 pounds and 5'11. As you see, the return date closed Nov 3 and I can't seem to find company contact info for Safco. Guess I'll deflate it and sew it myself. 155 dollars my ass!
