First-Rate Multiple Angle Toys R US Nabi / Nabi 2 Non-Skid Robust Table / Desk Tablet PC Portable Stand
I ordered 2 of these for my niece and nephew and it has been awesome.  Holds up the Nabi without any issues regardless of the grid on the back.  It is very sturdy...so much so that I ordered another one for my mom for her Nook.  It's also only $9.99 now.  I paid $12.95 each the first time.  Highly recommend...no need to purchase a more expensive stand and it folds up.  Great buy!
