If you get a 23x23 stand, the cage will hang over it.. and personally, that would make me nervous. We didn't really look to see if anyone made a stand. It was much cheaper to make our own, to be honest with you. You can check stores like Ikea, Best Buy, or someplace like that who sells entertainment units maybe? Or check where you got your cage from, maybe they have one or can steer you in the right direction?
I feel like almost everyone on here makes their own stands. They may not be as furniture looking as ours is, but look through some of the enclosure pictures people post in the enclosure section. I'm sure people would be willing to tell you exactly how they built them!
