This handy Sports-Portable model can be used in a "backless" chair. Works best in boats and bleachers and in similar backless sitting situations. Try it for meditation, yoga, sport events, camping, seminars, or stadium seating. Can also be used in many office chairs, dining chairs, and on couches. If used for driving, be sure to detach the straps.
Can also be used directly on the ground, but only if your hamstrings are flexible. If you have tight hamstrings, the support may tip backwards too far when you lean back.
