So the grid makes a good condition. Stramm during assembly but that will not do so otherwise. Bigger problem is that it can be found only in beds using actually, what has no bed frame / frame. Which has no bed linen box or frame for the mattress? The fewest. So you can use the grid already, but then with flaps nothing. You just caught a grid frame and it is no longer flexible. So There are max. 3 points, especially this is not at all apparent from the description.
