got mine from ikea. standard size, easy to get required parts such as mattress, bed sheet, bumper pad. dont get the cheapest one though, it looks flimsy, don't get the most expensive one either, not worth the money in my opinion. Preferably buy those that can change height.

Ikea cots does not comes with wheels, as it follows some safety standard. There are cots from Ikea which are made from solid wood. It's true that Ikea cot is not suitable if you are quite tall. Anyway, the baby might not be sleeping there up to 1 year old. My big boy slept in cot for around 6 months until he is able to turn over and move around until he got stuck.. my younger boy is still sleeping in the cot, 6 months old now, noy moving around much yet at the moment.
