ahNah> for your info, my baby cot has rollers, can be detached and the cot can be rocked. the rollers are helpful if you intend to move the bed ard. in my case, my #1 was sleeping with the confinement lady in the study room. after that in my room, later moved to his own room. oh ya, during the day time, we pushed the cot out to living room, for his afternoon nap and play. so the cot has really been moving ard in our flat. the rollers has stopper to secure it in place when you don't want it to move.
