We have the hyper Eden play pen and absolutely love it! It’s not super massive but big enough for my girl, her toys and her dad to be in there comfortably
We got the Ickle bubba playpen from Aldi for £29.99 - very cheap and very easy to use! It opens like and umbrella and closes easily too! I have carpal tunnel and I could still do it with ease. Has mesh and a zipped door for you to enter. But needs to be placed on a carpet / mat as the floor needs padding.
I have a dripex 150x200cm playpen. I got it second hand but its brilliant and massive. But recommend looking on fb marketplace
