Congratulations on a great product and a professional staff. I incidentally had an opportunity to try an Adaptic chair in a physical therapist's waiting room. I had never seen a chair so healthy yet comfortable before. After a short phone consultation with your staff, I bought one for myself. It arrived in two days, as promised. I'm happy to recommend this chair to basically anyone, for home or office use. I like the dynamics of the thing. The omnidirectional tilting seat, and smoothly adjustable arm- and headrest make it more or less impossible to get a stiff neck, legs or feet. It's certainly one of those small things that make your day better, healthier and more fun.
