The instructions to put this together were incredibly frustrating and difficult to understand. Some of the numbers don’t add up to the pieces you have laid in front of you. And the nuts and bolts aren’t included in the description of what’s needed at each step. The washers also.  The entire playground took us about 7 hours to complete. Some of the boards for the backing of the chalk wall wouldn’t screw in and stay. We had to put our own reinforcements on the back of it. Also the chalk wall is made up of a tarp type of material. It doesn’t feel very safe for the kids to be playing on the playground with a wall that isn’t very secure. Not very happy with this purchase. And just want to warn anyone who is interested in purchasing this. This was an entire day of frustration trying to set it up.  And  we had to guess at what the instructions were. Would I purchase again? No.
