Lifeboard Yoga Platform for Carpet/Outdoors

Do you like to do yoga at home, but have carpet at your house? I did (before I moved to an apartment with hardwood) so I bought this two-piece platform that perfectly fits a yoga mat and provides a stable, hard surface for doing yoga even on carpet or out in the grass. Easily deconstructs into two puzzle-like pieces that fit easily into a closet or under the couch.

Condition is basically new -- I didn't use it much before moving. Original price is $100 plus $20 shipping; I'm selling for $90.
