My daughter sat on my SP3 while the stand was out. It's useable but warped If anyone is wondering about those black marks on the edge underneath the stand, they're not actually scratches. There are two plastic tabs with black tops that I had to reinsert after taking the screws off the hinges. The black must somehow rub off on the edge when the tabs bend with the stand. Anyway I don't have accident cover so stuck with it.
