Large Round Black Mat. Easy assemble design. Sorry no pix of it set up, were on my daughter's cell which got lost.
Internet pix is the same design, but the spring cover pads are green on mine, not blue,
I paid $300.00 last year, & the kids used 4 months, before moving to an apartment.
Don't wanna store it all winter under the drafting table in the den, so the first $150.00 takes it home.
