The clear plexiglas lets me keep an eye on the kids while they're playing in their own little corner, which is exactly what I needed. They're solid enough that the toddlers can't knock them over but light enough to shift around when I rearrange the room.
The 1" depth gives these panels a really solid feel, not flimsy like I worried. I can see the whole play area through the clear plexiglas while still keeping the space divided, which is exactly what I needed.
Setting these up in my toddler room finally let me separate play zones without losing sight of anyone. The plexiglas is genuinely clear, so I can watch the kids from across the room, and the 1" depth makes them feel sturdy rather than flimsy.
