for the price: unbeatable.
The pad is solid. For the money I challenge you to find a better pad -- because that would be the pad I would want. This pad will give you the largest surface area and thickness of any pad. Slim chance to bottom out in the middle but unless you want to pay for a high end pad the seam problem is something everyone has to deal with on every pad so one can't fairly hold that against the Hera. Buy it, use it, have fun.
