The Champion Sports M290 set of 3 foam base comes with 1 heavy-duty nylon web strap and 1 steel spike per base. Each base is foam filled with a heavy-duty nylon quilted cover and measures 14 in x 14 in x 2 in.
Comments about Champion Sports M290 Set of 3 Stake Down Foam Bases (14"x14"x2"):
The product only comes with 3 spikes, so you will have to be very creative as to how you will anchor these. Sports Authority sent 3 more after my complaint. Make sure you do not hammer the straps that hold the spikes as it rips quite easily. It does set up quickly and is sturdy once anchored properly.
Bottom Line No, I would not recommend this to a friend
