I have wood floors so I went with this one...I love them and so does Harley, he goes right in when I call him
I have 2 of them I keep one 24x44 upstairs for bed time and I have a bigger one 24x57 I keep down stairs with his food/water/bed/toys in it for when I have to leave him for a few hours or if I'm busy and can't watch him.
I ordered both off Ebay
Easy to fold up and take with you for travel, and very easy to keep clean
24x44 was $45.00 and the 24x57 was $75.00
Hope this helps good luck with your search
