Baby cot with wheels or raised bed or drop sides?

[BlackWhiteCircle]

Due to back issues, looking for a cot with a higher base and drop down sides and possibly wheels to move it in and out from the bedside. Don’t need something to last until they are 4, just to get from 6months until moving to a floor bed. Can’t seem to find something and something not huge! Currently have the snuzpod studio but will need to move out of this when they can sit up.

Most cots with drop down sides have different heights you put the base at. You start at the highest level and lower it as they get bigger.

Thanks, I think the needed thing is wheels and adjustable bed height but then drop down last. Maybe one that’s only 60cm by 120cm not the standard 70x140 seeming
