Recommend a decent playpen for an active chunky 1 yo

[overcovermultitasker]

My DD is out of control in her exploring and I sometimes need to just keep her in one place so I can cook so I'm after a baby cage playpen, but needs to be robust as she's older. A lot look quite flimsy.---- Recommendations please?

We had the BabyDan hexagonal one. It opens out to a gate as well.

Ditto, to the above.
Only found it on our 3rd, although probably not about in 91
It was a life changer.
Plenty of room and brilliant for other stuff right up until they've finished making dens.

Oh great two recommendations for the same thing .. thanks @ExclamationPerfume @Devlesko
can they lean on it without it moving? My DD is such a strong baby. Looking online I just can't tell how things are.

Yes it's really strong. We only ever used it as a playpen. If you use it as a room divider I think you can attach it to the wall. We used it as a playpen for our puppy after. It's very well made.
