As Slidel says, you're looking for a good double ladder stand.

I've had good luck with [color:#3333FF]Big Game[/color][/b] brand tree stands.

I own 4 or their hang-ons and 1 ladder. All have been overbuilt and hold my overweight carcass up in the air nicely.

I'd look at something like their [b]Partner Pro ladder stand where the foot platform attaches to the tree.

They're generally heavy and made of steel, but they feel very sturdy once properly secured.

The first thing I do when I get one of their stands is to cut off their attachment strap/buckle setup and buy a Heavy Duty ratchet strap.

Their setup will hold and is probably easier to put up, but I like the sense of security a big ratchet strap with a safety factor of 4 gives...
