Childsafe Equipment Stands

A shared listening room with the family poses the challenge of an GOOD equipment stand that starts approx. 4 ft high to place amps & source equipment. Perhaps CD's/storage could be from ground to 4 ft before equipment shelfing starts. Anyone faces the same challenges and any recommendations? Many thanks.
Sorry, forgot to mention that I use tubes and want to get the little hands off the hot tubes! Current set up just high furniture shelfing.
I had one custom built (in oak), I have three young kids, if you'd like a pic, email me at
