If You Wanna Sit Like Champion, Ultimate is The one to Get
Best Seat Cushion I've tried. If you wanna absolute comfort & pain relief,  get the Ultimate One. I don't think other models of the line could do the same job as this thing. Ultimate one is thick plus you're getting 2 layers of hyper elastic polymer with two independent grids molded together. Price little steep at $149, but product advanced & it totally worth it. Overall 5-star product also made in Homeland Utah. Don't waste your time money alternative cheap  Chinese knock off ones. This thing also heavy with Cover almost 8.3 pounds. It says about quality lots of materials used in production.
