I, like the previously poster, love the massage chairs that you can try out for free here. This store is in a busy section of the high-end Plaza at the King of Prussia Mall. It is always quite crowded, but still, you can relax on the chairs, enjoy some gadgets, and not worry about being hassled by salespeople. I find this store has more items than the Sharper Image near me. Everything is on the pricey side, but that is to be expected, since the merchandise is unique and satisfies niches I never would have thought exist. The clerks are helpful, but when I asked for help getting back to where I entered, they too didn't know about the layout of this gargantuan mall.
