Pipsissewa, RePete & sargevining, sorry, I didn't mean to come across with negativity. I am open to any new innovation and wish anyone sincere kudos for innovating. I didn't realize the new hammock was still undergoing design when I saw the one posted on WH's website, I just assumed that was it.
Good point about a regular mattress not being dead flat, but needing to conform to the shape of the body. Looking forward to WH's final design and figuring out the references to Adirondack chairs. It brings to mind the plywood leg splint Charles and Ray Eames created for the military that began their careers. Here's hoping that lightning strikes here too!
