Here is a kit that helps you get started with meditation. The Now Kit Meditation Kit comes with a meditation bench, mat, and instruction card. The Now Bench is a reversible, closed-cell foam block that you can sit on flat or roll forward to adjust your leg angle. The mat takes the pressure off your knees, legs, and feet.
The bench is made of 3 layers and keeps you comfortable while meditating. You also get a guide to get started. More information is available here.
