Play pen advice and suggestions

Hi there I've been looking for a play pen for my rescued 6mo puppy. I've seen soooo many but I can't seem to find out which are the best ones to choose. It will be in my living room which is quite small but for her benefit I want it to be so that she can move around, play and nap. I've seen pop ups but they seem like they would just fall over if she jumps it leans on the side. Not really keen on the metal ones that look like a cage. Would really like your opinions about what you have and have experienced. My pup is 6kg at the moment but won't get bigger than 10kg (I believe, looking at the parents)

Thank you 💜
