I am moving apartments by myself and I got a convertible furniture/dolly to move my sofas and tvs and what not with ease but I have realized that my queen size mattress and boxspring is too wide to roll down a hallway width wise so I would have to carry it upright and I don't want to drag it on the floor as I'd probably get in trouble lol...so I need to somehow roll it....

Anyways, what would work better of these options...

I am thinking just put one of the 3 caster dolly's on the one end/corner of the mattress, then I can lift on the other end and just drag/push it that way? Or should I just be on the safe side and just get the floor dolly and put it under the middle of the mattress and drag it that way?

The 3 caster dolly is cheap but I am worried it will just slide out...
